1 Scope
This document specifies product characteristics, assessment methods, compliance criteria
of test results and a designation system for push-fit fittings for the purpose of
joining tubes of copper, plated copper, multilayer pipes and plastics pipes. The fitting
ends have a nominal diameter from 6 mm to 63 mm. The fittings are designed for a service
lifetime up to fifty years.
This document is applicable to push-fit fittings for joining one or more of the following
tubes or pipes:
-
— copper tubes according to EN 1057.
-
— plastics and multilayer pipes.
The fittings are used up to the operating temperatures and corresponding maximum operating
pressures as indicated in Annex A.
This document applies to copper alloy fittings. A non-exhaustive list of these copper
alloys is given in CEN/TS 13388.
Adaptor fittings can combine push-fit ends with fitting ends defined in the other
parts of EN 1254.
Push-fit fittings for metallic tubes can also have flanged end connections according
to EN 1092‑3.
Push-fit fittings can also have a plated or other decorative surface coating.
Fittings can be produced by machining, metal forming, casting, or fabrication.
Products covered by this document are intended to be used in liquid applications:
-
— hot, cold or combined hot and cold water, including systems according to the EN 806 series;
-
— closed heating systems according to EN 12828;
-
— cooling systems;
-
— drainage systems;
-
— fire protection systems including sprinkler systems according to EN 12845.
