The work of preparing International Standards is normally carried out through ISO technical committees. Each me
20、mber body interested 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 E
21、lectrotechnical 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 type
22、s of ISO documents 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.

29、 (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 to whether the
30、 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.Requirements and t
31、est methods for material and components, other than pipes, are specified in ISO 15876-1 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 characteristics
32、of pipes.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、lastics piping systems for hot and cold water installations Polybutene (PB) Part 2: Pipes1 ScopeThis document specifies the characteristics of pipes for 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
34、 not intended for human consumption (domestic systems), and for heating systems, under design pressures and temperatures appropriate to the class of application (see ISO 15876-1).The designation polybutene is used together with the abbreviation PB throughout this document.This document covers a rang
35、e of service conditions (application classes), design pressures and pipe dimension classes. For values of TD, Tmaxand Tmalin excess of those in ISO 15876-1, this document does not apply.NOTE 1 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspect
36、s, 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 p
37、ipes, their joints and to joints with components of PB, other plastics and non-plastics materials intended to be used for hot and cold water installations.It is applicable to pipes with or without (a) barrier layer(s).NOTE 2 In the case of plastics pipes provided with a thin barrier layer, e.g. to p
38、revent or greatly diminish the diffusion of gases and the transmission of light into or through the pipe wall, the design stress requirements are totally met by the base polymer (PB).2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their con

46、hase transition (usually called ageing) before it develops its final properties. The minimum required transition time depends on temperature and product characteristics. The same final material performance is obtained once completion of crystalline phase transition is achieved, irrespective of trans
47、ition conditions. For quality control purposes, therefore, test specimens shall be taken immediately after processing and be conditioned in accordance with recommendations obtained from the compound supplier prior to testing.The crystalline phase transition is dependent on time and temperature. For
48、guidance a minimum time of five days for PB-H and one day for PB-R should be allowed at 23 C, unless accelerated ageing is performed.NOTE The crystalline phase transition can be considerably accelerated upon applying higher hydrostatic pressure of approx. 1 kbar to 2 kbar. Accelerated ageing at high
49、er pressure can be accepted if test results can be proven reproducible and equal to those obtained at atmospheric pressure.Because of the slow crystallization, transformation and shrinkage which takes places after PB-H and PB-R plastics are cooled from the melt, physical testing should be delayed after extrusion or moulding until this morphological transition is complete.4.2 Evaluation of LPL-curvesThe pipe material shall be evaluated in accordance with ISO 9080 or equivalent where internal pressure tests are mad
