28、en made from polybutene (PB). The piping system is intended to be used for hot and cold water installations.In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by ISO 15876 (all parts): ISO 15876 (all parts) provides no inform
29、ation as to whether the product may be used without restriction in any of the Member States of the EU or EFTA; it should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in f
30、orce.Requirements and test methods for material and components of the piping system are specified in ISO 15876-1, ISO 15876-2 and ISO 15876-3. ISO/TS 15876-7 gives guidance for the assessment of conformity.This document specifies the characteristics of fitness for purpose of the piping systems.At th
31、e date of publication of this standard, System Standards for piping systems of other plastics materials used for the same application include ISO 15874, ISO 15875, ISO 15876, ISO 15877, ISO 21003 and ISO 22391.

33、e conveyance of water, whether or not intended for human consumption, (domestic systems) and for heating systems, under design pressures and temperatures according to the class of application (see ISO 15876-1).The designation polybutene is used together with the abbreviation PB throughout this docum
34、ent.This document covers a range of service conditions (application classes) and design pressure classes. For values of TD, Tmaxand Tmalin excess of those in ISO 15876-1:2016, Table 1, this document does not apply.NOTE It is the responsibility of the purchaser or specifier to make the appropriate se
35、lections 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 document.In conjunction with the other parts of ISO 15876, it is app
36、licable to PB pipes, 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.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content co
