Long-term leaktightness under internal hydraulic pressure

Test methods

A sample (pipe and/or accessory) is subjected to an internal hydrostatic pressure test simulating the expansion of the joint when subjected to fatigue.

Products to test

Plastics piping systems for civil works for water in:

  • Plastics piping systems for water supply and for buried and above-ground drainage and sewerage under pressure - Unplasticized poly(vinyl chloride) (PVC-U) EN ISO 1452-1, -2, -3, -5.
  • Conveyance of water under pressure made of oriented unplasticized Poly (vinyl chloride) (PVC-O) ISO 16422
  • Water supply of buried and above ground drainage, sewerage and irrigation water under pressure - Oriented unplasticized poly(vinyl chloride) (PVC-O) UNE EN 17176-2, -5 / CEN/TS 17176-3.
