ASTM A1056-12

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

SCOPE
1.1 This specification covers the materials and testing of cast iron couplings for joining hubless cast iron soil pipe and fittings for sizes 11/2 to 10 in.  
1.2 It is the purpose of this specification to furnish information as to the characteristics of a particular sleeve type coupling when applied to cast iron soil pipe and fittings manufactured in accordance with Specification A888, latest revision, and CISPI Designation 301, latest revision.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 The following precautionary caveat pertains only to the test method portion, Section 8, 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.
