ÖNORM EN ISO 18489

Issue date: 2025 11 01

Thermoplastic materials for piping systems - Determination of resistance to slow crack growth under cyclic loading - Cracked Round Bar (CRB) test method (ISO/DIS 18489:2025)

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.

Frequently Asked Questions about ÖNORM EN ISO 18489

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.

Find out more about the benefits of multi-user licences

Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
