ISO DIS 18489

Description / Abstract: This International Standard specifies a method to determine the resistance to slow crack growth (SCG) of polyethylene materials and pipes and fittings. The test is applicable to samples taken from compression moulded sheet or extruded pipes and injection moulded fittings in excess of 10 mm thickness.

This method is suitable for an accelerated fracture-mechanics characterization at ambient temperatures of 23 °C of different polyethylene grades, especially for PE 80 and PE 100 types for pipe applications, but can also be adapted for other thermoplastics materials using different test parameters, temperatures and applications.
