18、 15874-1:2013ISO 15874-1:2013(E)IntroductionThis part of ISO 15874 specifies the requirements for a piping system and its components when made from polypropylene (PP). The piping system is intended to be used for hot and cold water installations.Regarding potential undesirable effects on the quality
19、 of water intended for human consumption, caused by the product covered by ISO 15874 no information is provided as to whether the product can be used without restriction, and existing national regulations concerning the use and/or the characteristics of this product remain in force.Requirements and
20、test methods for components of the piping system are specified in ISO 15874-2 and ISO 15874-3. Characteristics for fitness of purpose (mainly for joints) are covered in ISO 15874-5. ISO/TS 15874-7 gives guidance for the assessment of conformity.This part of ISO 15874 specifies the general aspects of
21、 the plastics piping system.At the date of publication of this part of ISO 15874, the following system International Standards for piping systems of other plastics materials used for the same application areISO 15875, Plastics piping systems for hot and cold water installations Crosslinked polyethyl

27、 for hot and cold water installations Polypropylene (PP) Part 1: General1 ScopeThis part of ISO 15874 specifies the general aspects of polypropylene (PP) piping systems intended to be used for hot and cold water installations within buildings for the conveyance of water whether or not intended for h
28、uman consumption (domestic systems), and for heating systems, under design pressures and temperatures according to the class of application (see Table 1).It covers a range of service conditions (classes of application), design pressures and pipe dimension classes. Values of TD, Tmaxand Tmalin excess
29、 of those in Table 1 of this part of ISO 15874 do 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.I
30、t also specifies the test parameters for the test methods referred to in this part of ISO 15874.In conjunction with the other parts of ISO 15874, this part of ISO 15874 is applicable to PP pipes, fittings, their joints and to joints with components of other plastics and non-plastics materials intend
