ASTM International Standard Specification for Shielded Couplings Joining Hubless Cast Iron Soil Pipe and Fittings ASTM C1277-08

This specification covers the materials and testing of shield hubless couplings to join hubless cast iron soil pipe and fittings. Gaskets shall comply with the required physical and chemical properties, dimensions, and material specifications. The rubber gasket shall conform to the required physical requirements such as tensile strength, elongation, durometer, accelerated aging, compression set, oil immersion, ozone cracking, tear resistance, and water absorption. The shield and clamp assembly shall be made of material conforming to the requirements such as tensile strength and hardness. All parts shall be made of 300 series stainless steel, namely: Type 301; Type 304; Type 300; Type 301; and Type 305. The material shall also undergo physical tests like deflection, shear, and unstrained hydrostatic tests.
