This International Standard specifies a method to establish the quality of injection-moulded unplasti-cized polyvinyl chloride) (PVC-U) fittings using an oven.
It applies both to pressure fittings and to non-pressure fittings used for drainage applications, as well as to flanged fittings and fittings incorporating elastomeric sealing rings and to fittings consisting of the assembly of a number of moulded parts (e.g. union connectors).
