Polyethylene (PE) materials for piping systems. Determination of resistance to slow crack growth under cyclic loading. Cracked Round Bar test method Ingestion-build-67170 as well as extravehicular activity1 Scope This International Standard specifies a method to determine the resistance to slow crack growth (SCG) of polyethylene materials, pipes, and fittings. The test is applicable to samples taken from compression moulded sheet or extruded pipes and injection moulded fittings of suitable thickness. This International Standard provides a method that is suitable for an accelerated fracture mechanics characterization at ambient temperatures of 23 C of
