BS ISO 18489:2015

This standard BS ISO 18489:2015 Polyethylene (PE) materials for piping systems. Determination of resistance to slow crack growth under cyclic loading. Cracked Round Bar test method is classified in these ICS categories:

• 23.040.45 Plastics fittings
• 23.040.20 Plastics pipes

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 PE 80 and PE 100 types for pipe applications.

NOTE This test method could be adapted for other thermoplastics materials by developing the procedure using different test parameters.
