US TAG Annual Report for 2007

Prepared by

David M. Aikens, SC1 US Delegation Leader

General Comments

SC1 and its four active working groups met in Paris on June 26th to 28th, 2007. Representing the US were David Aikens of Savvy Optics, Allen Krisiloff of Triptar Lens, Ray Williamson of Ray Williamson Consulting, and Gene Kollenberg, Executive Director of OEOSC. The US delegation met by conference call two weeks prior to the meeting, and the day before the meeting, to review the comments that had been received and establish clear guidelines on the US positions and our presentation plans for the ISO meeting. This was very effective, and will be repeated before the next ISO meeting as well.

WG1 and WG2 have been focused on completing one major project this year; the reconciliation of ISO 14999-4 interferometric testing, with ISO 10110-5 and -14, the drawing notations for surface and wavefront error. Most of the technical time for both working groups during the Paris meeting was devoted to these activities. At this point, none of these standards are very good, having been arrived at as a compromise between vastly different objectives. The current version of ISO 10110-5 and -14 are useable, but no longer contain the very helpful table of Zernicke coefficients and equations. The fringe interpretation section of part 5 has been incorporated into ISO 14999-4 as an appendix. All three standards will now be released as ISO standards this year.

In addition to this work, WG1 and WG2 have several minor projects. One group of projects is associated with the measurement standards for OTF, MTF and other optical properties. As the result of a ruling by ISO General Secretariat, these standards need to be revised to replace the nomenclature in the equations for the optical functions (OTF, PSF, etc) With single letter functions. This work will continue over the next couple of years, with much disagreement from the technical attendees who object to this change. A second project is the final release of ISO 10110-12 for aspheric notation. It is now complete, and will be published in 2008.

In addition to these projects, there are several projects ongoing in WG1 and WG2, listed below. Most notable of these is the revision of ISO 10110-8, which will be led by the US delegation, and the completion of revision to ISO 10110-7. This last was the source of great consternation at the meeting in Paris, as the French and Russian delegations strove to re-instated Method II prior to revision of the standard. Their efforts were unsuccessful, and the standard will be published without Method II, due to the lack of clear documentation of the utility and effectiveness of the standard.

WG3 and WG4 were not attended by the US. As of the date of the meeting, no experts were available for either working group, even by correspondence. Since June, Gordon Boultbee has volunteered to serve on WG4 by correspondence, in addition to his current roles as SC3 Delegation leader and SC3/WG2 convener. Since neither session was attended by the US, not cogent comments can be made on their activities. Their active projects are listed below, however, for reference.

ISO/TC 172/SC 3 Optical Materials and Components


US TAG Annual Report for 2007


Prepared by


Gordon Boultbee, SC 3 US Delegation Leader


ISO/TC 172/SC 3 and its three working groups met in Kyoto, Japan on November 28-30, 2007. This was the first SC 3 meeting organized and hosted by JISC. The three experts from the US were Gordon Boultbee of JDSU and the WG 2 Convener; Leonard Hanssen of NIST; and Allen Krisiloff of Triptar Lens Co., Inc.


WG 1, Raw Optical Glass, is working on CD 12123, Specification of raw optical glass. It will advance to the DIS stage. The WG also is working on a round robin test of a method for classification of striae in optical glass. If the round robin is successful the PWI will be proposed as an AWI. Similarly, a round robin test is being developed pertaining to a test method and classification for the climate resistance of optical glass. A PWI ballot will be prepared to encourage participation in the round robin.


Three standards prepared by WG 1 that were up for systematic review were confirmed by SC 3.


WG 2, Coatings, has been revising three of the four parts of ISO 9211. Parts 1 and 2 will advance to the CD stage. Part 2 will incorporate an alternate method of specifying the cuton and cutoff slopes of optical filters, as requested by the US. Part 3, after much discussion of last minute changes proposed by the UK, was proposed to advance to publication as an ISO standard.


An omission was discovered in ISO 9211-4 shortly after its publication in 2006. The US will lead the effort to correct the omission via an amendment to the standard. While we are at it several other possible changes to the standard will be investigated.


The Japanese presented a conceptual approach to develop an instrument for very accurately measuring broadband high reflectance of optical elements. It will be 2009 before this concept is developed in enough detail to solicit suitable experts, etc.


WG 3, Characterization of IR Materials, began discussions on an AWI for characterization of optical materials used in the spectral range from 0.78 µm to 100 µm. Discussions were incomplete and will continue by e-mail correspondence with the intent of preparing a new WD.


The next meeting of SC 3 and its working groups is planned for Berlin in the 4th quarter of CY 2009.

December 2006

ISO/TC 172/SC 5 Microscopy and Endoscopes, Activity for 2007


SC 5 met in met in Xiamen China October 23-26.

Attending for the US Delegation was Lee Shuett, US TAG SC5 Leader; Osamu Joji, Olympus America and M J Cornelius FDA.


P-Members delegations represented were from Great Britain, Germany, Japan, China and Switzerland. P-Members not represented in the meeting: Austria (ON), Romania (ASRO), Russian Federation (GOST R), Republic of Korea.


Members of the first plenary meeting held October 23rd discussed the voting of the twelve systematic reviews. Six of them were voted "confirmation" unanimously by the P-member countries and are therewith automatically registered as confirmed. In detail these are ISO 12853, ISO 11883, ISO 8037-2, ISO 8577, ISO 8600-2 and ISO 8600-4.


The six remaining standards received in majority votes for a confirmation, but some P-members have voted for revision or amendment. Hence those reviews needed to be deliberated at the meeting for resolving the further processing:


ISO 8038-1:1997: "Screw threads for objectives and related nosepieces - Part 1: Screw thread type RMS (4/5 in x1/36 in)" (N 424)

Japan and USA have voted for revision/amendment, because it was decided last year that this standard shall be merged with ISO 8038-2, which is already undergoing a full revision. The secretary explained, that in this case the standard shall be confirmed and be withdrawn after the publication of the merger of ISO 8038-1 and -2 is available. All delegations agreed to this procedure.

Resolution Xiamen 113/2007

ISO 8255-2:1997: "Cover glasses - Part 2: Quality of materials, standards of finish and mode of packaging" (N 426)

Japan and USA have voted for revision/amendment, because it was decided last year that this standard shall be merged with ISO 8255-1, which is already undergoing a full revision. The secretary explained, that in this case the standard shall be confirmed and be withdrawn after the publication of the merger of ISO 8255-1 and -2 is available. All delegations agreed to this procedure.

Resolution Xiamen 114/2007

ISO 11882:1997: "Interfacing connection for 35 mm SLR photo cameras (T-thread adaptation)"(N 428)

USA has voted for withdrawal of this standard with the following argument: "T-thread adapters are no longer widely used in microscopy. They remain useful in astronomy however." After some debate and an enquiry among the delegations it appeared that these adapters are still in use worldwide. It was agreed that the standard shall be confirmed.

Resolution Xiamen 115/2007



ISO 8578:1997: "Marking of objectives and eyepieces" (N 427)

As a conclusion from the 2007 systematic review the Sub-committee decided that ISO 8578:1997 shall be revised. The new project was attributed to WG 9.


ISO 8039:1997, "Magnification" (N 425)

As a conclusion from the 2007 systematic review the Sub-committee decided that ISO 8039:1997 shall be revised. The new project was attributed to WG 3.


ISO 10934-1:2002 "Vocabulary for microscopy -- Part 1: Light microscopy" (N 429)

USA has voted for withdrawal of this standard with the following argument: "T-thread adapters are no longer widely used in microscopy. They remain useful in astronomy however" It was obvious that this vote was mistakenly doubled from ISO 11882:1997 (see above) and consistently the US delegation withdrew that comment and changed their vote to "confirmation". It was agreed that the standard shall be confirmed.

Resolution Xiamen 118/2007


Nomination of a new convenor for WG 3

The secretary informed the delegations, that after the retirement of Dr. Evennett (see N 417) BSI has relinquished the secretariat of WG 3, which subsequently was open for nominations. During the call for taking over the secretariat (see N 416) only one nomination (from DIN, Ralf Baur) was received. The secretariat nominated Mr. Shuett as new convenor. Since WG 3 is hosting the "Terms and Definitions" standards, it was seen as advantage, when the convenor is a native English speaker. SC 5 unanimously agreed to appoint Mr. Shuett as the new convenor of WG 3. It was acknowledged that DIN officially took the secretariat.

Resolution Xiamen 119/2007


Items to be addressed by the WGs and AHGs (e.g. nomination of experts)

The secretariat forceful reminded the delegations to check the current situation with their respective nominated experts in ISO Global Directory (for access to livelink). Each delegation urgently was requested to make any necessary changes via their officer in their national standards body. Some of the mailing lists are quite outdated and therefore not useful for documents distribution any more. Delegations were asked to fix the mailing lists and livelink accesses with their officers in the national standard bodies for the SC and all WGs by the end of this year.

Action: All delegations


The work program of WG 9 has increased considerably over the last years and it was noted that WG 9 needs more meeting time in the future. The secretary informed that except for the German and US delegation no country has nominated experts for the two AHGs. They will need more participation. After agreement of the work program the AHGs shall be elevated to a WG in order to be able to use Livelink as working tool.


Report on the working groups

These topics include "Terms and definitions of flexible endotherapy devices", "Terms and definitions of rigid endoscopic endotherapy devices" and "Reprocessing and maintenance requirements".


WG 9 "Optical performance of microscope components"

Report on the working group meeting and confirmation of results Kimiaki Yamamoto Convenor from Japan gave a verbal report on the WG 9 meeting in Xiamen The written document is a separate WG 3 document and is attached and made part of this report. The following conclusions and recommendations by the WG were adopted by the Subcommittee:


Revision of ISO 8038-1 and -2, "Screw threads for objectives and other related nosepieces"

The Japanese delegation is requested to draft a final manuscript for a NWIP which merges ISO 8038-1 and -2 after receiving the modified proposal from Germany. The deadline for submitting the draft to the Convener is 2008-01-08. SC 5 agreed to initiate a NWIP based on this final manuscript, and to complete the vote in time for discussion at the next SC 5 meeting.

Resolution Xiamen 121/2007


ISO 8578:1997: "Marking of objectives and eyepieces" (N 427)

The German delegation is requested to make a draft for a manuscript for revision of ISO 8578:1997. The deadline for submitting the draft to the Convener of WG 9 is 2008-07-01, which will then be presented to the WG 9 members for further discussion at the next meeting.

Resolution Xiamen 116/2007


Revision of ISO 9344, "Graticules"

The Japanese delegation is requested to draft a final manuscript for a NWIP for ISO 9344. The deadline for submitting the draft to the Convener is 2008-01-08. SC 5 agreed to initiate a NWIP based on this final manuscript and to complete the vote in time for discussion at the next SC 5 meeting.


Revision of ISO 8255-1 and -2, "Cover glasses"

Dr. Schadwinkel will revise and distribute the Project Leader proposal for ISO 8255-1, to be presented to the WG 9/PG members. The deadline for submitting the draft is 2008-01-08. The proposal will be then discussed with global manufacturers of coverglass by: Mr. Shuett/Mr. Joji in USA; Mr. Yamagishi/Mr. Shiihashi in Japan; Mr. Yeung in China; Dr. Schadwinkel/Mr. Euteneuer in Europe. The outcome of each of these discussions will be summarized by the WG 9/PG members and presented to Dr. Schadwinkel by 2008-04-01 at which time they will be used for inclusion in a final manuscript for a NWIP. SC 5 agreed on launching the NWIP with this manuscript.

Resolution Xiamen 123/2007

The chairman and secretary of SC 5 volunteered to investigate with the officers in ISO, Geneva, about the problem with marking with trade names or parts of trade names. The result of that research will be forwarded to the convenor of WG 9, which will distribute this to his WG. The WG 9 convenor will decide and take action about the next steps in due time before the next meeting.

Resolution Xiamen 125/2007


AHG 1 "Basic requirements for microscopes"

Report on activities

Thomas Bocher Convenor gave a verbal report on the AHG 1 meeting in Xiamen (a written report is available as a separate SC 5 document). More discussion and input from member delegations and end users concerning the requirements and scope of this new topic is needed. It is the request of AHG 1 to SC 5 to allow the AHG 1 to convene again at the next SC 5 meeting prior to moving this document to a NWIP.

Resolution Xiamen 126/2007


13 AHG 2 "Advanced methods of light microscopy"

Report on activities

Lee Shuett gave a verbal report on the AHG 2 meeting in Xiamen (a written report is available as a separate SC 5 document). More discussion and input from member delegations and end users concerning the requirements and scope of this new topic is needed. It is the request of AHG 2 to SC 5 to allow the AHG 2 to convene again at the next SC 5 meeting prior to moving this document to a NWIP.

Resolution Xiamen 127/2007


Other SC5 business

Report of liaison contact to IEC/SC 62D MT 16 "Electrical equipment in medical practice" (Roger Gray) Mr. Otani reported about the retirement of Roger Gray and therewith the loss of the liaison officer. He will contact Mr. David Barlow from USA if he accepts to take over the task as liaison officer between SC 5 and IEC/SC 62 D. If not, Mr. Otani will approach Mr. Paul Stevens from UK if he may accept this task.


ISO 10936-2:2001 "Operation microscopes – Part 2: Light hazard from operation microscopes used in ocular surgery" The secretary reported about the current status of that draft which is hosted by SC 7. The CD has received ten pages of comments and those will be resolved on a meeting of SC 7/WG 6 on 2007-11-01 in Tokyo. Outputs of this meeting will be reported by the secretary at the next meeting.


How to ensure/improve end customers input in the standardization work (Thomas Bocher)

The Japanese delegation does not see the necessity for customers/end users attending ISO meetings in principle, since those experts are invited to the national meetings. Customers input are collected that way. The German delegation questioned whether it is necessary to invite customers to the SC 5 meetings. Input is coming via the national meetings. Customers input are also here collected that way. The Chinese, Swiss, UK and US delegation argued the same way.


The secretary informed about the delegation principle for ISO meetings, where the countries are free to select and send the delegation from their national committee.


National committees were encouraged to get customers/end users interested in the standards work of the respective national committee, which then could delegate customers/end users to the ISO meetings. The chairman suggested to additionally using a second way to get customer/end users input via corresponding with those customers/end users not linked to any of the national committees. This applies for sure for all kinds of topics dealt within SC 5.


Approval of resolutions

The draft resolutions prepared by the drafting committee were displayed on screen during the meeting and the meeting carefully reviewed all of them. Adjustments or additions were incorporated, where necessary. All resolutions prepared during the meeting were unanimously adopted by the delegations present. All resolutions - with some finishing on their final wording by the secretary later - were approved by the meeting, are reproduced in Annex A to this report.


Requirements concerning a subsequent meeting

The UK delegation volunteered to investigate possibilities for a meeting in 2008 in England. Oxford as venue was focused, if possible at the Oxford University. There may be some restrictions with hotels etc., therefore as alternative Germany/Munich area was offered by the German delegation. As date 2008-09-22/26 was fixed. The next but one meeting in 2009 was planned, it was envisaged to be in Japan or in Germany/Munich area, if Oxford takes place in 2008

The following organizational proposals were made and confirmed by Sub-Committee 7 (SC7).


1) So that there may be continuity in the experts working within the various project groups the designation of experts will be formalized in the future so that both the secretariat of SC7 and the working group conveners will know who the designated participants are in each project group. In the past the participation in these groups was semi open to any person who happened to come to the SC7 meetings and as a result the project leader had no way of knowing if a given individual would continue to work on the project in the future. Now experts will be designated by their national bodies as experts to a stated project group and in addition, will be expected to participate in the work until it is finished. There is as also a guideline established for the number of experts per project group from each country. The resolution of SC7 on this issue in its entirety is:


Work programme management – Rules for participation in WG and PG


Noting the need of continuity in project work and hence in the composition of the responsible groups for them to be able to work in an effective manner, the Subcommittee resolved to lay down the following rules for working groups and project groups:


Working groups


The Subcommittee re-confirmed its decision taken at the 1997 meeting in Nagoya, on the general rule of a maximum of five experts per country per working group. Exceptions to this rule can be granted by the Subcommittee secretariat in case a valid justification be given.


The Subcommittee noted that ISO Global Directory currently allows member bodies to register more than 5 experts. The Subcommittee considers that this be on the understanding that these individuals are registered to have reading permission for the documents but only up to five experts will represent a country as the active members.


Project groups


The Subcommittee resolved to lay down the following rules for project groups:

  1. It is the understanding that there be one project group for each work item. This applies for both active work items and for preliminary work items.

  2. The project group comprises those experts that are nominated by the P-members when voting on the work item, either as a part of the Vote on NWIP or of the Systematic Review Ballot, or just after the new item has been approved and the work is to be started.

  3. The project group members are expected to make active participation and contribution over the lifetime of the project until its completion.

  4. The group is disbanded when the project is completed (i.e. at the time of publication of the standard).

  5. The number of experts per country per project group is limited to a maximum of two experts.

  6. The nomination to project groups shall be submitted from member bodies to the subcommittee secretariat.

  7. Observers (e.g. other WG experts) may attend in project group meetings but may not participate. Observers wishing to attend shall make contact with the project leader in due time before the meeting. Observers cannot attend if there is not enough space available in the meeting room.

  8. Any exception from these rules shall be subject to agreement between the project leader, convener and subcommittee secretariat.


2) A problem has arisen as a result of recent action by the ISO Central Secretariat to initiate very strict rules as to the time permitted for standards to be developed. If a work item is formally started and does not reach the various stages of development within the time limits imposed, the Central ISO Secretariat will unilaterally cancel the project and then, to complete the work, an entire new formal procedure must be done to reinitiate it. This is has already happened at least once to SC7 and it has the effect of slowing down an already very slow standard creation process. These development time problems arise due to the fact that there is often a good deal of negotiation and discussion at the early stages of the development of a new standard (or even when an existing standard is extensively revised), and as result it is very difficult to comply with the time limits imposed by the ISO Central Secretariat if the new work is started at the same time it is formally established as a new work item with the Central Secretariat. To deal with this problem SC7 has taken the following approach to the creation of standards as outlined in the resolution given below.


Work programme management – Prioritization of work items

The Subcommittee resolved that in order to adequately cope with its workload in an effective manner, an active approach shall be taken to prioritize work items. The preliminary stage will be typically used as a repository of work items which are either


3) To facilitate the effective development of a standard when a New Work Proposal is accepted and to prevent the revision of existing standard following a Systematic Review from expanding beyond the reasons given by the various member countries in their vote to revise the standard in question, the following resolution was adopted.


Work programme management – Scope of work item

The Subcommittee resolved that to work in an effective manner, it is of crucial importance that the scope of every project be clearly determined. An active work item may not be started unless the intended scope is sufficiently clear. During the lifetime of the project it shall be ensured that the work undertaken remains within the scope of the balloted work item. This shall apply for both work items resulting from circulation of a

New Work Item Proposal and for work items being started as a result of the Systematic Review Ballot.


4) It was also announced at the Tokyo meeting that the ISO policy for systematic review of issued standards has recently been slightly changed. Heretofore all issued standards were systematically reviewed at 5 year intervals. Now the first review of a newly created standard will occur 3 years after first issuance and then at 5 year intervals thereafter. This seems to have been done with the idea that at first no one knows if a new standard will cause problems until it has been used for a few years but that it is often found that needed changes come to light soon after an International Standard goes into general use. So by doing the first review 2 years earlier the initial changes can be quickly made and then not much change to the standard will be needed in the future. The effect of this new policy on SC7 will be to increase the work load slightly as the newer standards will need to be reviewed sooner than in the past. Realization of this was in part the reason that it was felt that resolution 3) above was needed so that we could efficiently deal with early revisions without getting into situations where complete standards were rewritten instead of just fixed.


Contentious issues that arose at the Tokyo meetings


1) There was one quite contentious issue that arose at the secondary plenary meeting having to with the definition of vertex power, the refractive power of ophthalmic lenses. This issue also caused quite a bit of contention at the working group meetings for spectacle lenses, WG3, and at the new working group for Devices for Dioptric Power Measurement of Lenses, WG10. As it turns out, the light path through the older, manual focusing focimeters is slightly different from the light path through automatic focimeters when lenses are measured at locations where there is a prism effect. This causes the light beams to be tilted slightly differently with respect the surfaces of the lens and so causes a slight change in the focusing of the light. Certain elements of the spectacle lens community would like to pick one or the other measurement method as the standard. However, were this to be done, it would put manufacturers of the other type of focimeter at a commercial disadvantage because the lens manufacturers could claim that a focimeter using the method that did not conform to the standard was invalid as a measuring instrument. There is no clinical reason to prefer one method of measurement to the other, as the differences in measured power are not clinically significant. There does not seem to be a compelling reason for the lens manufacturers to choose one or the other as far as we can tell. However these considerations do not seem to influence those who want a choice to be made. Over the objections of China, Japan and the United States, SC7 adopted a resolution to ask each member country to pick the method they prefer. The United States objected because it is our position that no choice need be made and that if one were to be made, that choice would violate the ISO policy that no standard shall put a company at a commercial disadvantage if their product can meet minimum performance standards for the task it is designed to accomplish.


2) In the spectacle lens area there is a standard being developed for finished spectacles. Heretofore only semi-finished and finished, but not mounted spectacle lenses, were standardized at the international level. On the other hand, the United States has for half a century had a standard on finished spectacle lenses, the standard being Z80.1, the first standard created by ACS Z80. The tolerances found in Z80.1 have been refined over the years by the joint work of the spectacle lens manufacturers, the optical laboratories, whose job it is to create finished lens to individual patient prescriptions from semi-finished blank lenses and other to create complete finished spectacle pairs, and the ophthalmic clinical practitioners – the optometrists, the ophthalmologists and the opticians. The Z80.1 standards allow spectacles to be created that are able to be economically produced with minimal waste but which also give good correction of vision in a clinical setting. However the project group creating the International Standard for finished spectacle pairs decided on tolerance tighter than the Z80.1 tolerance, primarily due to influence from the European Union spectacle lens manufacturers. The United States responded to this, when it was found that merely explaining why the United States had chosen the tolerances found in the Z80.1 did not change the minds of others, by running trials both in the United States and in Europe to see what the actual quality of finished spectacle pairs was when they were made in daily manufacture. These studies not only showed that the U.S. tolerance were reasonable but also refuted the European claim that spectacles in Europe were routinely made that conformed to the tighter tolerances. This factual evidence had no effect on the opinions of the project group members outside the United States and so a standard will be created that the United States will not accept.


It is situations of this type that make the United States unwilling to accept ISO standards in a blanket fashion, as has been requested of us by others in SC7 and by the central ISO organization. It must be remembered that the United States has only one vote within ISO/TC172/SC7, as do other large nations such as China and Japan, whereas each member of the European Union has an individual vote thus giving the EU a majority in almost all cases, as the EU members tend to vote as a block due to the fact that International Standards are mandatory standards within the EU. This situation has been long recognized by the United States and while we fully participate in the creation of ophthalmic standards, we judge each international standard on its own merit and compatibility with United States consensus standards before accepting it as a United States standard.


Other activity at the Tokyo meetings


Work at the Tokyo meeting by the Ophthalmic Instruments and Test Methods working group (WG6), by the Implants working group (WG7) and by the Contact Lens working group (WG9) went well from the point of view of the United States.


The active project within WG6 to revise the tonometer standard will be led by an expert from the United States.


Three preliminary projects were created within WG7 on various aspects of intraocular lenses. All three projects will be led by experts from the United States.


Two preliminary projects within WG9 were upgraded to active projects.

An expert from the United States will lead each of these projects, which deal with various aspects of contact lens care products.


One preliminary project on methods for the determination of shelf-life of contact lenses was created within WG9. It will be led by an expert from the United States.



Work of SC7 in 2007


During the course of the year the work of the various working groups, as represented by the documents prepared and voted on, was as follows;


NWIP (new work item proposals) – 4

WG2 – 1

WG3– 2

WG9 – 2


CD (committee drafts) - 4

WG3 agree with comment- 1

WG6 agree with comment - 1

WG7 disagree – 1

WG9 agree with comment -1


DIS (draft international standard) – 3

WG6 agree –3/2 with comment


FDIS (final draft international standard) - 1

WG7 agree – 1


Systematic 5-year review – 15

WG2 – 2 confirm

WG3 – 3 revise

WG6 – 4, confirm 2, revise 2

WG9 - 6, confirm 3, revise 3


Technical reports

WG2 –1

WG6 - 1


It can be seen that the work of SC7 in 2007 includes work at all stages of the standardization process but at a lower overall level than in the past. Quite a number of issued standards came up for systematic review in 2007. This will to be the trend in SC7 due to the large number of standards the subcommittee has created over that last 25 years.


Work by the various working groups within SC7


WG2 – A technical specification on a method for the simulation of wear and detection of nickel release from metal and combination spectacle frames was published in 2007. Work began in 2007 on a new work item to create a standard for a spectacle frames electronic catalog and identification. This work is being as a joint effort with WG8.


WG3 – The major issue being addressed by WG3 continued to be the standardization of finished spectacle lenses. The position of the United States on this work was discussed above. A Technical Report on parameters effecting lens power measurement was published in 2007. This report only covers spectacle lenses.


WG6 – The revision of existing standards was essentially finished in 2007 as all work items had, at year-end, progressed to the DIS stage. 2 revised standards were published in 2007 along with a new Technical Report on Light Hazards to the eye.


WG7 – One International Standard relating to intraocular lenses, which was created by WG7 was published in 2007. It was a revision of one of the 7 parts of the overall International intraocular lens standard, ISO 11979. Just before the Tokyo meeting the Food and Drug Administration raised an issue on level of endotoxins allowed to be present on intraocular lenses following manufacture. Based on some reported problems with endotoxins that inadvertently made their way in some IV fluids and subsequently caused some eye inflammation following their use in ophthalmic surgery, the FDA became concerned about the tolerances for endotoxins found on interocular lenses following manufacture. There was not time to submit a New Work Item proposal to form to project group to address this issue prior to the meeting in Tokyo but this issue will be addressed in the coming year.


WG8 – Data Interchange – A new work item was proposed and accepted to create a standard for an electronic catalog for spectacle frames and their identification. This work is being done as a joint effort with WG2.


WG9 – Contact Lenses has been addressing issue raised in the area of care solution compatibility with contact lens materials due to introduction into the business of silicon hydrogel materials. It is not clear exactly how to treat this new and very popular material. The United States has taken the lead in addressing this issue.

The following document-related resolutions were made at the June 2006 Boulder meeting (included for reference purposes – copied from SC 9 Annual Report for 2006):

    1. Item 11146 series, Lasers and laser-related equipment – Test methods for laser beam widths, divergence angles and beam propagation ratios: It was agreed to issue new work item proposals to start a revision of the three parts of the ISO 11146 series.

    2. Item 11254 series, Lasers and laser-related equipment – Determination of laser-induced damage threshold of optical surfaces: In consideration of resolution 347 (London 15) and the recommendations of WG 6, it was agreed to issue new work item proposals for the revision and restructure of the 11254 series for parts 1 to 3 as follows: Part 1: Definitions and general principles; Part 2: Threshold determination; Part 3: Assurance of laser power (energy) handling capabilities. The standards will be published under the ISO number 21254. Furthermore, it was decided to develop a part 4 as a Technical Report (English only): ISO/TR 21254-4 - Lasers and laser-related equipment – Determination of laser-induced damage threshold of optical surfaces – Part 4: Inspection, detection and measurement.

    3. Item 11553-1, Safety of machinery – Laser processing machines – Part 1: General safety requirements (Amendment 1 to ISO 11553-1:2005): It was decided that the approved NWIP for an Amendment 1 to ISO 11553-1:2000 shall result in a Part 3 of the dual logo ISO/IEC 11553 instead of an Amendment of Part 1, in order to allow a better accomplishment of the noise requirements of the EU and of the semiconductor industry. The title of ISO project 11553-3 shall read: Safety of machinery – Laser processing machines – Part 3: Requirements for noise hazards.

    4. Item 11553-2, Safety of machinery – Laser processing machines – Part 2: Safety requirements for hand-held and hand-operated machines: An amended FDIS manuscript (resolving the negative assessments of the CEN Consultants for machinery and noise) is to be submitted to SC 9 members for voting and comment.

    5. Item 11810-2, Lasers and laser-related equipment – Test method and classification for the laser resistance of surgical drapes and/or patient protective covers – Part 2: Secondary ignition: An FDIS manuscript is to be submitted to SC 9 members for voting and comment.

    6. Item 11990-2, Optics and photonics – Lasers and laser-related equipment – Part 2: Determination of laser resistance of tracheal tube cuffs: It was agreed to issue a new work item proposal for a part 2 of ISO 11990 in order to specify a test method for the determination of the laser resistance of tracheal tube cuffs.

    7. Item 12005, Lasers and laser-related equipment – Test methods for laser beam parameters – Polarization: It was agreed to issue a new work item proposal to investigate the need for a revision of ISO 12005:2000.

    8. Item 13694, Optics and optical instruments – Lasers and laser-related equipment – Test methods for laser beam power (energy) density distribution: It was agreed to refrain from revising ISO 13694:2000 and to keep the determination of 'goodness of fit' deleted from the document as per Technical Corrigendum 1:2005-11 to ISO 13694:2000.

    9. Item 14880-1, Optics and photonics – Microlens arrays – Part 1: Vocabulary: It was agreed to issue a new work item proposal for a revision of ISO 14880-1:2001 in order to deal with the comments from Japan and USA listed in document N 306 (Report of systematic review) and in order to incorporate Technical Corrections 1 and 2 into the standard. The work item shall be registered as a preliminary work item (stage 00.20) in the work program of SC 9 and a new work item proposal will be circulated for vote after availability of a working draft.

    10. Item 14880-5, Optics and photonics – Microlens arrays – Part 5: Guidance on testing: It was recognized that New Work Item Proposal N 299 for a part 5 of the ISO 14880 series was intended to introduce a project aiming to a Technical Report instead of an International Standard into the work program of SC 9. Further, due to the positive vote of a majority of the P-members (N 309), SC 9 is to request that the ISO Central Secretariat register work item ISO/TR 14880-5 Optics and photonics – Microlens arrays – Part 5: Guidance on testing.



SC 9 continues in its intention to contribute to the ISO/TC 172 Online Properties Dictionary (approved ISO/TC 172 Work Item 23584). Initially, the Secretariat will upload standardized terminology from ISO 11145 (Optics and optical instruments – Lasers and laser-related equipment – Vocabulary and symbols), ISO 11807-1 (Integrated optics – Vocabulary – Part 1: Basic terms and symbols) and -2 (Integrated optics – Vocabulary – Part 2: Terms used in classification), ISO 14880-1 (Optics and photonics – Microlens arrays – Part 1: Vocabulary), ISO 15367-1 (Lasers and laser-related equipment – Test methods for determination of the shape of a laser beam wavefront – Part 1: Terminology and fundamental aspects), and ISO 15902 (Optics and photonics – Diffractive optics – Vocabulary) to the ISO/TC 172 properties server. Additional terms, definitions and contributions will follow.



The next meeting of ISO/TC 172/SC 9 is tentatively scheduled to be held in Berlin, Germany on June 9-11, 2008.
