Determination of thickness and mass per unit area - Bitumen sheets for roof waterproofing Ingestion-build-177197 ISO/IEC 17021-1 specifies requirements for1 Scope This European Standard specifies a method for the determination of thickness and mass per unit area of bitumen sheets for roof waterproofing. The measurement of thickness is appropriate for most bitumen sheets including sheets with a factory applied mineral finish The determination of thickness is not applicable to sheets with pronounced surface texture or to sheets with a substantial fibrous backing.
