19、ments for a piping system when made from polypropylene (PP). The piping system is intended to be used for hot and cold water installations.Regarding potential adverse effects on the quality of water intended for human consumption, caused by the product covered by ISO 15874 no information is provided
20、 as to whether the product can be used without restriction; existing national regulations concerning the use and/or the characteristics of this product remain in force.Requirements and test methods for material and components, other than pipes, are specified in ISO 15874-1 and ISO 15874-3. Character
21、istics for fitness for purpose (mainly for joints) are covered in ISO 15874-5.
