1. Call to order
The Division Director, F. Hengstberger, opened the meeting and welcomed all
present. He introduced the Division officers present (Associate Directors,
Secretary, and Editor) and asked all present to briefly introduce
themselves.

2. Approval of agenda
The circulated agenda was approved with adding "Approval of 1995 Div.2
meeting minutes" and "Director's report".

3. Approval of 1995 Division 2 meeting minutes
The circulated minutes were approved with one correction: J. M. Coutin
(France) is added in the attendees list. (A letter was received later from
J. Gardner correcting that he was listed but not present.)

4. Director's report (F. Hengstberger)
The former Division Secretary, A. Bittar (New Zealand), had a
reorganization at his institute, and became unable to continue his CIE
work. This cast a serious urgent problem for the Division. The Division
Director, F. Hengstberger, carefully considered candidates for the new
secretary and requested Y. Ohno (USA) to fill in this responsibility.
After careful consideration, he accepted this request. The Director
expressed his thanks to Y. Ohno for accepting to be the new Division
Secretary.

The Director and the new Secretary compiled the minutes of the 1995
Division 2 meeting in New Delhi, without information from the former
Secretary. The minutes therefore may lack in accuracy.

5. Secretary's report (Y. Ohno)
Ohno accepted to be the new Secretary in June 1996. As soon as he was on
board, he worked with the Director to organize this 1996 Division 2 meeting
in Vienna. The Secretary expressed his thanks to Dr. Schanda and Ms.
Hermann for their kind arrangements at CIE CB for this meeting.

The minutes of the 1995 Division 2 meeting in New Delhi were compiled and
distributed in the Division 2 Circular dated June 20, 1996.

The Division 2 mailing list was succeeded from the former Secretary, and
was updated to include e-mail addresses and fax numbers. 14 more people
were added to make the total number of 92 persons in the list. The country
members now count 34. The current list contains 46 e-mail addresses and 70
valid fax numbers. The Secretary has access to fax-modem service which
allows to send information through e-mail system. Effort will be continued
to provide faster and easier communication between Division 2 members.

CIE Central Bureau has established a Web page on Internet:
http://www.cie.co.at/cie/home.html
This home page should be utilized further to disseminate updated
information such as status and members of Technical Committees,
announcement of Division meetings, etc.

6. Editor's report (J. Moore)
The Division Editor received and edited technical report drafts from TC2-10
and TC2-14, and CIE standards drafts from TC2-33 and TC2-35.

TC2-17, TC2-33, TC2-35, TC2-36, TC2-39, and TC2-40 are currently listed as
standards committees. However, the Editor found that TC2-17, TC2-36, and
TC2-39 were going to produce technical reports, not CIE standards. The
standards committee list will be corrected. Some of these TCs may be
producing CIE standards after finishing technical report, in which case, a
new TC should be established for writing CIE standards.

All the TC chairpersons working on standards should be aware of the
differences and should follow the Code of Procedure for Drafting and
Presentation of CIE Standards issuied by the CIE CB. This is based on
IEC/ISO Directives - Part 3."

Some mechanism is needed in the Division to oversee, on regular basis,
existing standards, activities of TCs writing standards, and needs for
future standards. The Division Officers will take measures.

7. Progress report of Technical Committees

7.1 Associate Director G. Vandermeersh

TC2-10 Photometry and Goniophotometry of Luminaires
CM: G. Vandermeersch (Belgium)
ML: Almasi (Hungary), Blaser (Switzlerland), Blochouse (Belgium), Corrons
(Spain), Price (Great Britain), Lewin (US), Rattunde (Germany), Soardo
(Italy), Claassens (NL)
TR: Prepare a report on the photometric characteristics of luminaires and
their measurement.
ST: The report was fully edited by Division Editor, and Division ballot
was done. There was one negative vote from Netherlands, one abstain from
Sweden, and three votes with comments. Glare from luminaires was an issue
in the negative vote. Lack of references (IEC documents) and lack of
preciseness of some of requirements (bare lamp ambient temp and position,
partial luminance of luminaires, etc.) were cited. Selection of
goniophotometers was dropped from its scope, and will be a future area to
work. Division 2 agreed to submit the document to Board Meeting after minor
modifications by the chairman. The new document (Pub.121) will replace
Pub. 24 and Pub.27. The Pub. 43 is kept current. The new document will be
presented at the next Division 4 meeting in October 96. (There was a
press release in Sep. 1997 on the publication of this document.)

Discussion on numbering of documents
J. Moore raised a concern about numbering of the CIE documents. If a new
document replaces an old document, the new document should have the same
number with additional edition number, like No.15.2. The document
numbering is now not consistent. There should be a written procedure for
numbering including cases for editorial changes and figure changes. Many
agreed, and the Director will raise this problem at the Board meeting.

(Germany)
TR: To rewrite CIE Standard S001 in terms of thermodynamic temperatures,
and in a manner such that the spectral distributions of the standard
illuminants are preserved, but are independent of international temperature
scales.
ST: The draft was balloted and approved by TC. National committee ballot
is in progress. In the process of German translation by H. Terstiege,
changes were suggested to remove the word "standard" before sources, and to
make clear the secondary status of Illuminant C and other D illuminants
relative to the International Standard sources A and D65. This suggestion
will be considered by Editor and CIECB.

TC2-35 CIE Standard for V(l) and V'(l)
CM: K. Mielenz (USA)

(Germany), Schanda (Hungary)
TR: To prepare a new CIE Standard on the present V(l) and V'(l) functions.
ST: The draft was edited by Division Editor which resulted in extensive
change of document format. The edited draft was circulated, and some major
questions and comments were raised (not necessarily due to change by
Editor). Ad-hoc meeting was held by Div.2 Secretary on 30 August in Vienna
to obtain more comments and opinions by other members. At Div.2 meeting,
change of the title of the documents was suggested, to make it similar to
the title of the TC. The next decision is left to the chairman.

ST: TC met in Sweden, in June 1996. The first draft was made. TC plans
to meet again in October 96 in order to involve some interested members
from Division 4. The current TC is producing a technical report. The
terms of reference (which refers to CIE standards) will be changed
accordingly. By his letter, the chairman urged the need for coordination
of meetings between Div. 2 and Div. 4.
(The TC met in Poitiers, France on Oct. 18, 1996 in conjunction with Div. 4
meeting. The chairman hopes to have a TC-approved draft at South Africa
meeting.)

TC2-37 Photometry Using Detectors as Transfer Standards
CM: Y. Ohno (USA)

The tolerances for such parameters as central axis, angular beam apertures,
size of sphere ports, illuminated sample area, sphere diameter,
detector-sample distances, angles etc. will be considered and their
influence on the accuracy of the measurements results relative to the
characteristics of the measured material will be analyzed. Depending on
the material to be measured, the outcome of the TC work may be the
specification of several geometric tolerance levels.
ST: TC met twice this year, in the US, and 30 August in Vienna. As the
TC is preparing a technical report rather than CIE standard, change of
Terms of Reference is proposed. Div.2 agreed on the change and will be
submitted for Board approval. The proposed TR is:
Compile a technical report and recommendations specifying the
geometric tolerances for the various geometries in colorimetry, including
0/45, 0/d and others. Parts of this technical report may be suitable for
inclusion in a CIE standard specifying several geometric tolerance levels.

other interested people. CIECB will do duplication and circulation to the
members. CIECB is working on the electronic form of the list for easier
circulation.

9. Liaison report

CCPR (A. Parr, USA)
Since no report was received from A. Parr, the Director requested R.
Kohler of BIPM to give a report. Five intercomparisons by CCPR are in
progress. There are 15 participants for the cryogenic radiometer
intercomparison. The illuminance responsivity intercomparison will start
with 16 participants and with BIPM as the central lab. Luminous intensity
and luminous flux intercomparison is now prepared by PTB. Intercomparisons
for aperture area (run by NIST) and Spectral radiance using strip lamps
(run by VNIIOFI) are also scheduled. The report of these intercomparisons
should be ready at the next CCPR meeting in 1998.

ISO/TC6 (J. Zwinkels)
The working group met 3 times in 1995 in Berlin, Montreal and Beijing.
J.Zwinkels attended the meeting in Montreal. The major issues discussed
were: ISO/TC6 standardizing and authorized laboratories; in particular, the
status of the current NRC-PTB intercomparison of diffuse reflectance
scales; liaison with ISO/TC42 and ISO/TC130 viewing conditions and the
application to paper of D50 Illuminant; and ISO draft standards for: CIE
Whiteness (D65/10¯ and Measurement of Specular Gloss at 75 and 20¯)

ICO (F. Hengstberger)
Watching the news letter. Looking for new liaison person.

IMEKO (J. Schanda)
There was a TC2 meeting, but Schanda could not attend. H. Kaase (Germany)
is the chairman of the TC.

10. Proposal for new TCs and reporterships

There was a proposal from G. Sauter (Germany) for a new TC: Determination
of measurement uncertainties in photometry. TR: To prepare a CIE
recommendation as basis for the determination of measurement uncertainties
valid for quantities used in photometry.
The Div. 2 agreed to establish this TC. R. Kohler, J. Moore, A. Corrons,
T. Goodman, and Y. Ohno expressed their wish to join this TC.
( This new TC was approved as TC2-43 by Board meeting in Sept. 1996)

T. Goodman proposed the establishment of a new reportership : Use of
detectors as absolute transfer standards for spectroradiometry; N. Fox
(Great Britain) to be appointed as the reporter. Div.2 agreed to establish
this reportership. (This reporter is assigned as R2-21)

11. Future meetings:
1997 CIE Div. 2 will meet in conjunction with the CIE Midterm Session in
the first week of September, Durban, South Africa. There will also be 3
day conference of lighting in developing countries. Division meetings
(Divs. 2, 3, 4, and 7) are planned for the same week. The Director will
raise at the Board meeting the need for coordination of the meeting
schedules between Div. 2 and Div. 4. Div.1 will meet in conjunction with
AIC97 in May in Kyoto, Japan. NEWRAD is planned for the first week of
October, at Univ. Arizona.

1997 J. Schanda announced that CIECB is planning a CIE Seminar on LED
Measurements in Nov. or Dec. at Central Bureau in Vienna. The Seminar is
supported by Div.2.
