Scope

This standard applies to the requirements for suitable light sources used for sensitometer exposure of photographic materials. The light sources can be monochromatic or colored, that is, based on the spectral transmittance through a typical camera lens (see Table 3), the spectrum of the exposure radiant energy The properties must be consistent with the energy distribution of the general sunlight spectrum, except for infrared rays.
