International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the In

28、om 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 information as t
29、o 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 force.Requi
30、rements and test methods for material and components of the piping systems are specified in ISO 15876-2 and ISO 15876-3. Characteristics for fitness for purpose (mainly for joints) are covered in ISO 15876-5. ISO/TS 15876-7 gives guidance for the assessment of conformity.This document specifies the
31、general aspects of the plastics piping system.At the 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、onveyance 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 Table 1).The designation polybutene is used together with the abbreviation PB throughout this document.This
34、document covers a range of service conditions (application classes) and design pressure and pipe dimension classes. Values of TD, Tmaxand Tmalin excess of those in Table 1 do not apply.NOTE It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects,
35、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, this document is applicable to PB pipe
