Paper and board. Determination of opacity (paper backing). Diffuse reflectance method Ingestion-build-82396 BS ISO 8528-5 defines terms1 Scope This International Standard specifies a method for the determination of the opacity (paper backing) of paper by diffuse reflectance. It can be used to determine the opacity of papers or boards which contain fluorescent whitening agents, provided the UV content of the radiation incident on the test piece has been adjusted to conform to that in the CIE illuminant C using a fluorescent reference standard provided by an ISO TC 6 authorized
