Difficulties arise in the measurement of the colour of luminescent surfaces because of the lack of suitable sources. In general a close simulation of standard daylight illuminant D65 is used, in combination with a spectrometer. A better procedure, but more expensive and time-consuming, is to irradiate the specimen through a first monochrometer and to analyse the reflected and luminesced radiation through a second monochrometer. A set of luminescent materials have been circulated to six European laboratories for measurement by different techniques. In this report the results of the intercomparison are presented and analysed in detail. The report also discusses the origin of discrepancies and the physical origin of the slight changes in the colour of the samples that have been observed to take place between the initial and final measurements at BAM. Comments are made concerning production of luminescent colour standards to be certified and used worldwide.
