This International Standard specifies methods of test for fittings of any form, i.e. bends, branches, tapers,intended to be used in plastics piping systems for pressure and non-pressure drainage and sewerage or watersupply made of glass-reinforced thermosetting plastics (GRP). This International Standard is applicable tofittings, in order to test their structural design, but is not applicable to connecting joint systems. It assumesthat the fitting either is or is not intended to be subject to the effects of hydrostatic end thrust.The tests detailed in 8.1 to 8.4 are applicable to fittings intended to be used in buried or non-buriedapplications.These test procedures are applicable to fittings of all nominal sizes specified in the referring standard.The tests are for evaluating fittings intended for use in applications conveying liquids at temperaturesspecified in the referring standards.The test procedures in this International Standard are damaging to the test piece which will not besuitable for reuse after these tests. The test procedure is applicable to type testing.NOTE This International Standard is not intended to be used for the assessment of the performance of nonintegratedjoints as there are already international test methods for this purpose.
