Internal leaktightness with angular deviation

Test methods

A sample (pipe and/or accessory) is subjected to internal pressure for a set period of time, while also being subjected to angular deviation. The absence of any leakage is verified during the test.

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 in pipes made from unplasticized Poly (vinyl chloride) (PVC-O) ISO 16422
  • Water supply for buried and above ground drainage, sewerage and irrigation under pressure - Oriented unplasticized poly(vinyl chloride) (PVC-O) EN 17176-2, -5 ( CEN/TS 17176-3.
