标准范围
This International Standard describes the general procedure for measuring the diffuse radiance factor of alltypes of pulp, paper and board. More particularly, it specifies in detail in Annex A the characteristics of theequipment to be used for such measurements, and in Annex B the procedures to be used for calibrating thatequipment.This International Standard may be used to measure the radiance factors and related properties of materialscontaining fluorescent whitening agents, provided that the UV radiation content in the illumination has beenadjusted to the level specified in the specific International Standard describing the measurement of theproperty in question.This International Standard describes in Annex C the preparation of fluorescent reference standards, althoughthe procedures for using these standards are not included, since their use is described in detail in the specificInternational Standards describing the measurement of the properties of materials containing fluorescentwhitening agents.
