scope:

This Part of ISO 15877 specifies the general requirements of chlorinated poly(vinyl chloride) (PVC-C) piping systems intended to be used for hot and cold water installations within buildings for the conveyance of water, whether or not intended for human consumption (domestic systems) and for heating systems, under design pressures and temperatures appropriate to the class of application (see Table 1). This standard covers a range of service conditions (classes of application), design pressures and pipe dimension classes. For values of TD, Tmax and Tmal in excess of those in Table 1, this standard does not apply. It also specifies the test parameters for the test methods referred to in this standard. In conjunction with the other Parts of ISO 15877 (see Foreword) it is applicable to PVC-C pipes and fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for hot and cold water installations.
