ASTM C1277-97

Standard Specification for Shielded Couplings Joining Hubless Cast Iron Soil Pipe and Fittings

SCOPE
1.1 This specification covers the evaluating of the performance of shielded hubless couplings to join hubless cast iron soil pipe and fittings.
1.2 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only.
1.3 The following precautionary caveat pertains only to the test method portion, Section 7, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
