This International Standard specifies a method of test for verification of the rupture strength under internal hydrostatic pressure of fittings of injection-moulded unplasticized polyvinyl chloride (PVC) with elastic sealing ring type joints for unplasticized polyvinyl chloride (PVC) pressure pipes, with no I imitation as to the type and design of fittings and joints used.
It provides specifications for minimal strength requirements of the tested fitting with a specified pressure much higher than the nominal pressure for which the pipes are designed.
It is only applicable to fittings designed for pipes having a nominal diameter less than or equal to 160 mm (6 in).
