Anotace textu normy ASTM D4551-26 :

This specification covers poly(vinyl chloride) flexible sheeting which is used without mastic, bedding, or coating for construction of concealed water containment membranes that include fountains, pools, planters, shower and safe pans, tile tubs, or similar wet installations where the membrane is inaccessible once the construction is complete. The plastic materials shall meet the inherent viscosity and compound density requirements and shall be subjected to tests that have been selected to be conducted primarily with liquids that simulate the environment to which the membrane will be subjected during actual use. Qualification tests shall be performed wherein the sheeting shall conform to the following physical property requirements: thickness; stress-strain properties such as tensile strength, tensile stress at elongation, and elongation at break; tear resistance; pinholes; microorganism resistance; puncture resistance; indentation resistance; folding resistance; chemical resistance to distilled water, soapy water, or alkali; hydrostatic pressure resistance; shrinkage; and volatile loss.
