21、O 15876-3:2017ISO 15876-3:2017(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body inter

22、ested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical

23、 Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO docume

24、nts should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsi

The piping system is intended to be used for hot and cold water instal

31、lations.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 to whether the product may be used without restriction in any of the Member States of the E

32、U 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.Requirements and test methods for materials and components, other than fittings, are specified

33、in ISO 15876-1 and ISO 15876-2. 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 characteristics of the fittings.At the date of publication of this standard, System Stand

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 selections from these aspects, taking into account their particular requirements and any relevan

38、t national regulations and installation practices or codes.It also specifies the parameters for the test methods referred to in this document.In conjunction with the other parts of ISO 15876, this document is applicable to fittings made from PB and to fittings made from other materials which are int

39、ended to be fitted to pipes conforming to ISO 15876-2 for hot and cold water installations, whereby the joints conform to the requirements of ISO 15876-5.This document is applicable to fittings of the following types: socket fusion fittings; electrofusion fittings; mechanical fittings; fittings with

40、 incorporated inserts.It is also applicable to fittings made from alternative materials which, when fitted to pipes conforming to ISO 15876-2, conform to the requirements of ISO 15876-5.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their
