This specification covers the performance evaluation of heavy duty shielded couplings to join hubless cast iron soil pipe and fittings. Physical properties of all stainless steel and gaskets shall comply with the specified values. Requirements for the elastomeric gasket, clamp assembly, and couplings such as coupling width are detailed. The test apparatus for deflection test, shear test, and unrestrained hydrostatic joint test are illustrated.
