The piping system is intended to be used for hot and cold water installations.Regarding potential undesirable effects on t

21、he quality 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.Require

22、ments and test methods for materials and components, other than fittings, are specified in ISO 15874-1 and ISO 15874-2. Characteristics for fitness for 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 specif

23、ies the characteristics of the fittings.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 are ISO 15875, Plastics piping systems for hot and cold water installations Crosslin
