Abstract
This European Standard specifies a method for the determination of thickness and mass per unit area of bitumen sheetsfor roof waterproofing. The measurement of thickness is appropriate for most bitumen sheets including sheets with afactory applied mineral finishThe determination of thickness is not applicable to sheets with pronounced surface texture or to sheets with a substantialfibrous backing. Where it is required to characterize these products, mass per unit area should be used instead.The determination of mass per unit area serves to verify the value stated by the manufacturer for information and isnot applicable to perforated materials.
