Temperature Cycling Tester

The temperature cycling tester is designed to determine the resistance and stability of thermoplastic pipe systems when subjected to specified cycling times under specified internal pressure load. This applies to pipework systems intended to be used for conveying hot and cold pressurized water.


  • It establishes a classification system for common service conditions for pressurized hot and cold water systems. It gives a basis for evaluation and design of thermoplastics pipes and fittings in relation to the system performance requirements.
  • It applies to plastics piping systems used to carry water in distribution systems of hot and cold water, including potable water, and in transportation systems of hot water for heating, under design pressures according to the specifications according to the relevant Standards.
