8. Progress Reports from Technical Committees, Reporters, and Liaison Persons
8.1. Associate Director Johnson and TC chairpersons
Reports on TCs 2- 17, 19, 25, 28, 32, 39, 42, 44, 51, 53, 56, 57 were given.
8.2. Associate Director Sauter and TC chairpersons
Reports on TCs 2-16, 29, 37, 40, 43, 45, 46, 47, 48, 58, 59, 60 were given.
8.3. Associate Director Vandermeersch and TC chairpersons
Reports on TCs 2-23, 49, 50, 52 were given.
The reports given for 8.1, 8.2 and 8.3 are summarized below in the numerical order of all
the TCs.
TC2-16 Characterization of the performance of tristimulus colorimeters
Chair: J. Schanda (Hungary) AD: Sauter
ML: Bittar (New Zealand), Denner (South Africa), Goodman (UK), Gundlach (Germany),
Hengstberger (South Africa), Moore (UK), Muray (USA), Ohno (USA), Oleari (Italy),
Pointer (UK), Rastello (Italy), Rattunde (Germany), Sakai (Japan), Sauter (Germany),
Sugiyama (Japan), Terstiege (Germany) † – revised Nov. 2005.
TR: To produce a report recommending methods for assessing the performance of
tristimulus colorimeter heads for measuring chromaticity coordinates.
ST: AD Sauter reported for the TCC. The TCC changed last year from Rastello to Schanda.
The 11 th draft was discussed chapter by chapter at the meeting on 16 May 2005 and
participants agreed on minor changes to be made in the final draft. The TC agreed that
Draft 12 will be sent for TC ballot, and if accepted, to Divisional and BA ballot.
TC2-17 Recommendation for integrated irradiance and spectral distribution of simulated
solar radiation
Chair: G. Zerlaut (USA) AD: Johnson
ML: Chomiczewski (USA), Cordo (USA), DePietro (USA), Ellersick (USA), Christiaens
(France), Grossman (USA), Gueymard (USA), Ketola (USA), Martin (USA), Myers
(USA), Riedl (Germany), Robbins III (USA), Schoenlein (Germany), Scott (USA),
Severon (Germany) – revised March 2006.
TR: Revise and update CIE Publication No.20 (1972)
ST: Bergman reported for the TCC. A key objective of the TC is to use the SMARTS2
solar radiation model (developed by Gueymard) to establish new tables of spectral
energy distributions which can be used as references for the simulation of solar
radiation for specific applications. A rationale for updating CIE 85 has been prepared,
based on a comparison of SMARTS2 and CIE 85. There was a meeting of US
interests on January 25, 2005 in Ft. Lauderdale, FL. The TCC proposes a meeting in
Europe in the third quarter of 2005.
Discussion: Schanda commented that this TC should be aware of the activity of TC1-66
(indoor daylight spectral distribution for colorimetry), which is focused on the effects
of window materials and requests from an ISO committee, and should make sure the
results of the two TCs are not in conflict. DD Goodman suggested that the TC should
also liaise with work in Div. 3 related to indoor daylight solar distribution.
Hengstberger commented that the international daylight measurement program is also
