This part of ISO 9393 specifies the test parameters and conditions for hydrostatic-pressure tests on valves made of the following thermoplastic materials:
-- ABS, as defined in ISO 15493
-- PE 80, as defined in ISO 15494
-- PE 100, as defined in ISO 15494
-- PP-H, as defined in ISO 15494
-- PP-B, as defined in ISO 15494
-- PP-R, as defined in ISO 15494
-- PP-R-GF
-- PVC-C, as defined in ISO 15493
-- PVC-U, as defined in ISO 15493
-- PVDF, as defined in ISO 10931
NOTE Materials designation according to ISO 1043-1 and ISO 1043-2 for reinforcing materials.
The tests cover the following aspects:
-- the material used for manufacturing valves;
-- the pressurized valve components;
-- the complete valve.
