Test items for PVC pipes

For PVC drain pipes


According to relative standard(ISO4435), Unplasticized polyvinyl chloride (PVC-U)pipes and fittings

For buried drainage and sewerage systems need taking the following test:

E.X. factory test:

1.Longitudinal reversion (Ventilated oven)

2.falling mass impact test(Falling mass impact testing machine+Low temperature thermostat)

3.Methylene chloride soak test (Methylene chloride soak tester)

Formal test:

1. Ring-stiffness test (universal testing machine)

2. Density (Density tester)

3. Vicat softening point test ((HDT&vicat softening point testing machine)

4.Connection seal performance test (Hydrostatic pressure testing machine)

 

For PVC pressure pipes

 

According to the standard of

ISO4422 :Pipes and fittings made of unplasticized poly(vinyl chloride) (PVC-U) for water supply

UPVC pipe for water supply need the following test
