标准范围
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 compressionmoulded sheet or extruded pipes and injection moulded fittings of suitable thickness.This International Standard provides a method that is suitable for an accelerated fracture-mechanicscharacterization at ambient temperatures of 23 °C of different polyethylene grades, especially for PE 80and PE 100 types for pipe applications.NOTE This test method could be adapted for other thermoplastics materials by developing the procedureusing different test parameters.
