Gives rules for the measurement of the spectral reflectance of plane surfaces and spectral transmittance of plane parallel elements using spectrophotometers over the spectral range 190 nm to 25 µm. Applies only to measurements of the regular transmittance and the diffuse reflectance;it does not apply to those of the diffuse transmittance and the diffuse reflectance. Is applicable to test specimens which are coated optical components without optical power.
