This specification covers preformed thermoset rubber gaskets used to join hubless cast iron pipes and fittings.
Hubless cast iron soil pipe and fittings, shielded couplings, gasket sleeves,
Currently hubless cast iron soil pipe and fittings are joined by stainless steel shielded couplings requiring a polychloroprene gasket sleeve covered by ASTM C564. At a recent ASTM A04.75 subcommittee meeting the subcommittee discussed supply problems with polychloroprene and the need to investigate other types of elastomers. ASTM C564 is found in all the shielded coupling standards for shielded stainless steel shielded couplings. The users would be the coupling manufacturers who currently are using ASTM C564.
The title and scope are in draft form and are under development within this ASTM Committee.
