Thermoplastics pipes for the conveyance of fluids. Determination of the slow cracking resistance of pipes and fittings using the Notched Ring Test (NRT) Ingestion-build-111333 IEC 61853-3 describes the calculation1 Scope This Technical Specification determines the slow cracking resistance of pipes and fittings using the Notched Ring Test (NRT) which is a method for determining the slow crack resistance of thermoplastics resins and compounds in pipe form and or finished products (e. g. pipes and fittings) from which a ring specimen can be cut and notched. The test is performed under sustained constant loading in a test medium at a specified temperature and the
