BS EN ISO 15875-3:2003+A1:2020

This Part of ENISO15875 specifies the characteristics of fittings for crosslinked polyethylene (PE-X) piping systems intended to be used for hot and cold water installations within buildings for the conveyance of water, whether or not intended for human consumption, (domestic systems) and for heating systems, under design pressures and temperatures appropriate to the class of application (see Table1 of ENISO15875‑1:2003).

This standard covers a range of service conditions (application classes) and design pressure classes. For values of T_D, T_max and T_mal in excess of those in Table1 of Part1, this standard 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 relevant national regulations and installation practices or codes.

It also specifies the test parameters for the test methods referred to in this standard.

In conjunction with the other Parts of ENISO15875:2003 (see Foreword) it is applicable to fittings made from crosslinked polyethylene (PE-X) and to fittings made from other materials which are intended to be fitted to pipes conforming to ENISO15875‑2:2003 for hot and cold water installations and whereby the joints conform to the requirements of ENISO15875‑5.

This standard is applicable to fittings of the following types:

• mechanical fittings;

• electrofusion fittings;

• fittings with incorporated inserts.
