Standards Development
This document specifies a method to determine the resistance to slow crack growth (SCG) of thermoplastic materials, pipes, and fittings. The test is applicable to samples taken from compression moulded sheets, extruded rods, sheets or pipes and injection moulded fittings of suitable thickness.
This document provides a method that is suitable for an accelerated fracture-mechanics characterization at ambient temperatures of 23 °C.
This document specifies test parameters for polyethylene (PE), polypropylene (PP) and unplasticized polyamide (PA-U).
Furthermore, this test can be applied to characterise the slow crack growth resistance of virgin, as well as non-virgin (reused, recycled) thermoplastic materials.
[5]This test method can be adapted for other thermoplastics materials by developing the procedure using different test parameters.
