标准范围

This International Standard describes the general procedure for measuring the diffuse radiance factor ofall types of pulp, paper and board. More particularly, it specifies in detail in Annex A the characteristicsof the equipment to be used for such measurements, and in Annex B the procedures to be used forcalibrating that equipment.This International Standard may be used to measure the diffuse radiance factors and related propertiesof materials containing fluorescent whitening agents, provided that the UV-content of the instrumentillumination has been adjusted to give the same level of fluorescence as a fluorescent reference standardfor a selected CIE illuminant, in accordance with the specific International Standard describing themeasurement of the property in question.This International Standard describes in Annex C the preparation of fluorescent reference standards,although the procedures for using these standards are not included, since their use is described indetail in the specific International Standards describing the measurement of the properties of materialscontaining fluorescent whitening agents.
