Anotace textu normy ASTM D5926-25 :

This specification describes material and physical requirements for virgin nonrigid poly(vinyl chloride) (PVC) preformed molded and spliced gaskets used in mechanical couplings for gravity flow drain, waste, and vent (DWV), sewer, sanitary, and storm plumbing systems. They include couplings that join similar and dissimilar piping sizes and piping materials. Recycled materials may also be used in this product. Properly sampled specimens shall undergo tests, and shall conform accordingly to the following property requirements: durometer hardness; tensile strength; volatile loss; brittleness temperature; hardness increase, loss in tensile strength, and loss in elongation after heat aging; water absorption and weight increase; cracks and ozone resistance; volume increase and decrease after oil immersion; stress relaxation; and force retention.
