Resistance of joint couplings to temperature cycles

Test methods

An assembly of pipes and accessories is subjected to temperature cycles by passing hot water under pressure, alternating between hot and cold for a set number of cycles. During this test the parts are kept under traction and/or flexure and inspections are made for possible signs of leaks.

Limitation: We are able to test up to DN63.

Products to test

Plastics piping systems for hot and cold water in buildings made of:

  • Polypropylene (PP) EN ISO 15874-1, -2, -3, -5
  • Cross-linked polyethylene (PE-X) EN ISO 15875-1, -2, -3, -5
  • Polybutylene (PP) EN ISO 15876-1, -2, -3, -5
  • Chlorinated poly (vinyl chloride) (PVC-C) EN ISO 15877-1, -2, -3, -5
  • Multilayer EN ISO 21003-1, -2, -3, -5
  • Raised temperature resistance (PE-RT) EN ISO 22391-1, -2, -3, -5
