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 part of ISO 15877 covers a range of service conditions (classes of application), design pressures and pipe dimension classes. For values of T_D, T_max and T_mal in excess of those in Table 1, this part of ISO 15877 does not apply.

NOTE It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.

It also specifies the test parameters for the test methods referred to in this part of ISO 15877.

In conjunction with the other parts of ISO 15877, it is applicable to PVC-C pipes and fittings, their joints and joints with components of other plastics and non-plastics materials intended to be used for hot and cold water installations.
