15、pared by Technical Committee CEN/TC 133, Copper and copper alloys, the Secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 1998, and conflicting national stan
16、dards shall be withdrawn at the latest by July 1998. Within its programme of work, Technical Committee CEN/TC 133 requested CEN/TC 133/WG 8, Copper and copper alloy fittings, to prepare the following standard: EN 1254-3, Copper and copper alloys Plumbing fittings Part 3: Fittings with compression en
17、ds for use with plastics pipes. This standard is one of five parts for copper and copper alloy fittings for joining copper tubes or plastics pipes. The other four parts of the standard are: EN 1254-1, Copper and copper alloys Plumbing fittings Part 1: Fittings with ends for capillary soldering or ca
18、pillary brazing to copper tubes. EN 1254-2, Copper and copper alloys Plumbing fittings Part 2: Fittings with compression ends for use with copper tubes. EN 1254-4, Copper and copper alloys Plumbing fittings Part 4: Fittings combining other end connections with capillary or compression ends. EN 1254-
19、5, Copper and copper alloys Plumbing fittings Part 5: Fittings with short ends for capillary brazing to copper tubes. It is recommended that fittings manufactured to this standard are certified as conforming to the requirements of this standard, based on third party testing and continuing surveillan
20、ce, which should be coupled with an assessment of a suppliers quality system against the appropriate standard, i.e. EN ISO 9001 or EN ISO 9002. In respect of potential adverse effects on the quality of water intended for human consumption caused by the product covered by this standard: a) this stand
21、ard provides no information as to whether the product may be used without restriction in any of the Member States of the EU or EFTA; b) it should be noted that, while awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of
22、 this product remain in force. The attention of the user of this standard is drawn to the fact that national or local regulations or practices might restrict the choice of dimensions and threads in the application of products conforming to this standard. According to the CEN/CENELEC Internal Regulat
23、ions, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the Uni

This part of EN 1254 specifies connection end dimensions of compression ends for the purpose of joining plastics pipes for use in cold or combined hot and cold water systems or non-fuel gas systems. Fittings may comprise a combination of any of the end types s
30、pecified in EN 1254-1 to EN 1254-5 or other standards. The standard establishes a designation system for the fittings. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications.
