Flexible sheets for waterproofing. Bitumen, plastic and rubber sheets for roof waterproofing. Determination of watertightness Ingestion-build-141043 they need refractory materials of1 Scope This European Standard applies to bitumen, plastic and rubber sheets for roof waterproofing and specifies procedures for determining the watertightness, i. e. the resistance to ponding water or to hydraulic pressure absorbed by a limited part of the surface, of factory made products. This standard may also be used in other waterproofing areas.
