Copper and copper alloys - Plumbing fittings - Part 6: Push-fit fittings for use with metallic tubes, plastics and multilayer pipes; German version EN 1254-6:2021+A1:2025
Abstract
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
