This supplement applies to the testing of socket joints and is valid for heated tool socket and electrofusion fittings welded to pipes with a minimum wall thickness of 5 mm. The procedures are given in directive DVS 2203-4 except for the sampling, preparation of test specimens, recommended test stress and the evaluation of the test results. The test results can be used for comparative purposes and can be used to optimize e.g. the welding process or the construction of the fitting. The comparison between electrofusion and heated tool socket fitting systems is not possible without additional analysis.
