DANSK DSF/FPREN ISO 15876-2 PDF

This Part of EN ISO 15876 specifies the general aspects of polybutene-1 (PB-1) 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 EN ISO 15876-1). For the sake of simplicity the designation polybutene is used together with the abbreviation PB throughout this document. This standard covers a range of service conditions (application classes), design pressures and pipe dimension classes. For values of TD, Tmax and Tmal in excess of those in Table 1of Part 1, this standard 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 standard. ISO 15876 is a reference product standard. It is applicable to pipes, fittings, their joints, and also to joints with components made of other plastics and non-plastics materials intended to be used for hot and cold water installations. This part of ISO 15876 is intended for use only in conjunction with all the other parts of ISO 15876. It is applicable to pipes with or without (a) barrier layer(s).
