ASTM C1185-23

Anotace textu normy ASTM C1185-23 :

These test methods cover sampling and testing of non-asbestos fiber-cement flat sheets, roofing shingles, siding shingles, and clapboards. These products may be smooth or surface textured. The following test methods shall be performed: acceptable quality level; flexural strength; density; dimensional measurements; moisture movement; water absorption; moisture content; water tightness; freeze/thaw for cladding products; warm water; heat/rain–wall structures; heat/rain–roof structures; and freeze/thaw–roofing products.
