This volume contains short Technical Reports, Research Notes and Reporters' Reports prepared by various Technical Committees and Reporters within Division 2. In part they were published in the CIE Journal between 1987 and 1988.-\n--\n-114/1 Survey of reference materials for testing the performance of spectrophotometers and colorimeters-\n-This Research Note was originally published in CIE-Journal, Vol. 6, No. 1, 23-31, 1987.-\n--\n-A list of reference materials for testing the performance of spectrophotometers and colorimeters are given. Particular attention is paid to materials for the measurement of regular transmittance and for regular (specular) and diffuse reflectance. Materials for the calibration of wavelength scales and the measurement of stray light are also included. No examples were found of reference materials for the measurement of diffuse transmittance. Information on type of materials, suppliers, sizes available and calibration details is supplied.-\n--\n-114/2 International intercomparison on transmittance measurement-\n-Report of results and conclusions. This Research Note was originally published in CIE-Journal, Vol. 7, No. 1, 21-28, 1988.-\n--\n-Between 1978 and 1982, CIE TC 2-09 conducted an international intercomparison to assess the accuracy of transmittance measurements. Sixteen laboratories, including eleven national standardizing laboratories, took part in the intercomparison. Twelve sets of filters were used, each consisting of nine glass filters. The filters were selected so that the repeatability, linearity, wavelength accuracy, and stray light of the measurements could be characterized.-\n--\n-114/3 Intercomparison of luminous flux measurements on HPMV lamps-\n--\n-The results are given of an intercomparison of measurements of the luminous flux of a group of HPMV lamps, carried out among 21 commercial and national laboratories located in 14 different countries. The results reported by 16 of the laboratories lay within approx. +/- 1,5% of the mean level and all but two of the laboratories were within +/- 3% of the mean level. The consistency of the measurements can be regarded as fully adequate for most lighting applications.
