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 different polyethylene grades, especially for PE80 and PE100 types for pipe applications.
NOTE This test method could be adapted for other thermoplastics materials by developing the procedure using different test parameters.
