ASTM C1628-19(2024)

Anotace textu normy ASTM C1628-19(2024) :

This specification covers flexible leak resistant joints for concrete gravity flow sewer pipes using rubber gaskets for sealing the joints, where measurable or defined infiltration or exfiltration is a factor of the design. The gasket shall be fabricated from a rubber compound, the basic polymer of which shall be natural rubber, synthetic rubber, or a blend of both. Gaskets shall be manufactured in the specified design sizes and dimensions, conforming to both circular cross-section or "O-ring" gaskets, and non-circular cross-sections or "profile" gaskets. The joints shall also be made to meet design requirements as to confined circular cross-section and non-circular cross-section gasket joint designs. Volume, non-circular shape stretch height, and length of the manufactured gaskets shall be determined, while, the joints shall be evaluated according to their performances in hydrostatic and structural tests. The finished products shall be handled, stored, inspected, and marked appropriately.
