标准范围
This part of ISO 12625 specifies the testing procedures for the instrumental determination of the opacityof tissue paper or tissue products by diffuse reflectance using a paper backing.This part of ISO 12625 contains specific instructions for the preparation of test pieces of single-ply andmulti-ply products, where special preparation/procedures might be necessary.It can be used to determine the opacity of tissue paper and tissue products containing fluorescentwhitening agents, provided the UV content of the radiation incident on the test piece has been adjusted toconform to that in the CIE illuminant C using a fluorescent reference standard provided by an authorizedlaboratory as described in ISO 2470-1.This part of ISO 12625 is not applicable to coloured tissue paper and tissue products which incorporatefluorescent dyes or pigments.
