Liaisons Report (June 2004)
 
Division 8 (A. Kravetz)
Technical Report of TC8-01 (Colour Appearance Modeling for Colour Management Applications) was balloted and passed. Also, Technical Report of TC8-03 (Gamut Mapping) was balloted and passed. TC8-04 report (Chromatic Adaptation Under Mixed Illumination Condition When Comparing Softcopy and Hardcopy Mixed Illumination Condition When Comparing Softcopy and Hardcopy) is under TC ballot. For the status of other TCs, see the full report by A. Kravetz (Attachment 3).
 
CCPR - Comité Consultatif de Photométrie et Radiométrie (Y. Ohno)
There were CCPR Working Group meetings at NIST in May 2004, in conjunction with CORM 2004. Working Group (WG) on Key Comparisons (WG-KC), WG on Calibration and Measurement Capability (WG-CMC), and WG on UV (WG-UV) met, as well as a few task group meetings on individual Key Comparisons. Currently seven Key Comparisons and two supplementary comparisons are in progress, as reported last year. WG-KC (Al Parr, Chair) discusses various common issues in running Key Comparisons as well as individual issues. Recently, the methods for calculation of the key comparison reference value were at issue. Currently, a guideline for preparation of key comparison reports is being developed (task group under Y. Ohno). WG-CMC (F. Hengstberger, Chair) was formed last year to establish and maintain lists of CMC service categories, and draw up rules for the preparation of CMC entries. At the last meeting, the service categories for Round 3 submission were discussed and agreed. WG-UV (E. Ikonen, Chair) discusses various issues in UV metrology (synchrotron radiation, cryogenic radiometry, transfer standards, etc.) and encourages coordination of the work among NMIs.

ISO TC6/WG3 Paper, board & pulps - optical properties (J. Zwinkels)
A report that Zwinkels prepared of the CIE meeting in San Diego was discussed at the last ISO TC6/WG3 meeting. The WG is satisfied that the CIE has agreed to retain the reference to the C-illuminant in the new Colorimetry document (CIE Publication 15.3), in order to meet the needs of ISO/TC6. The WG is also very interested in participating in the new CIE D1 Reportership on the need to define an indoor daylight illuminant. WG members, A. Bristow and B. Jordan have already been in contact with the CIE Reporter, Dr. Janós Schanda, to inform him of the needs of the paper industry. Dr. Byron Jordan (Canada) was appointed official liaison from ISO/WG3 to CIE.
 
IEC TC34 Lamps and related equipment (G. Vandermeersch)
No report received. Partially covered in TC2-52 report.
 
ISO on reflectance and transmittance issues (D. Rich)
No report received. AD Johnson will follow up on this.
 
IDA (J. Rennilson)
No report received. Johnson mentioned that Rennilson is mostly retired and a new liaison person may be needed if this function is to be kept. He will contact Rennilson for his recommendation.
 
OIML (G. Sauter)
Sauter reported. There are no issues to be reported this time. Keep this function open.
 
IALA (International Association of Lighthouse Authorities) (C. Andersen/ I. Tutt)
Tutt reported. The name of the organization changed to "International Association of Marine Aids to Navigation & Light House Authorities." IALA is considering using blue lights (LEDs) for warning lights. There is some evidence that LED lights (including white) are more conspicuous than incandescent lights. Blue and yellow lights (alternating) are being considered for wreck marker buoys.
 
IEC TC100 (Color measurement and management in multimedia systems) (D. Rich)
No report received.
