| Resumen: | 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. |
