New Specification for Draft title: Specification for alternative rubber gaskets used to seal joints in cast iron soil pipe and fittings, primarily in Drain, Waste, and Vent (DWV) systems.
1. Scope
Creation of a new standard that defines an alternative material and performance requirements for compression gaskets used in bell-and-spigot or no-hub cast iron pipes. For use if polychloroprene is no longer available for purchase for the use in ASTM C564 gaskets. first task is those that have a rubber compound to be reviewed by the committee submit to the collaboration room for review. Please provide any test results for performance test requirements of ASTM C564 for comparison.
Keywords
cast iron joining methods, cast iron joints, elastomer, neoprene
Rationale
In the event polychloroprene, the primary elastomer for ASTM C564 gaskets is no longer manufactured. The A04.75 group identified the need to begin creation of an alternative rubber compound that meets all performance requirements of ASTM C564.
