21、the latest by April 2013, and conflicting national standards shall be withdrawn at the latest by April 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or a

22、ll such patent rights. Within its programme of work, Technical Committee CEN/TC 133 requested CEN/TC 133/WG 8 “Fittings“ to prepare the following European Standard: EN 1254-8, Copper and copper alloys Plumbing fittings Part 8: Fittings with press ends for use with plastics and multilayer pipes EN 12

This European Standard provides the basis for the assessment of a man

28、ufacturers production process for products manufactured in accordance with this European Standard. DIN EN 1254-8:2012-12 EN 1254-8:2012 (E) 6 1 Scope This European Standard specifies materials and test requirements for fittings of copper and copper alloys. This part of EN 1254 specifies press end co

29、nnections with or without plating or coating in the size range 10 mm to 110 mm for the purpose of joining plastics and multilayer pipes for use in hot and cold water systems according to EN 806, which are designed for service lifetime up to fifty years, as well as heating and cooling systems or gas

30、systems, including fuel gas systems. Fittings may comprise a combination of end types, specified in this European Standard, EN 1254, or other standards, providing they are suitable for the fluid / gas being conveyed. The European Standard establishes a designation system for the fittings. This Europ

31、ean Standard is applicable to press fittings for joining the following plastics and multilayer pipes: EN ISO 15874, Plastics piping systems for hot and cold water installations Polypropylene (PP); EN ISO 15875, Plastics piping systems for hot and cold water installations Crosslinked polyethylene (PE

32、-X); EN ISO 15876, Plastics piping systems for hot and cold water installations Polybutylene (PB); EN ISO 15877, Plastics piping systems for hot and cold water installations Chlorinated poly (vinyl chloride) (PVC-C); EN ISO 21003, Multilayer piping systems for hot and cold water installations inside

33、 buildings; EN ISO 22391, Plastics piping systems for hot and cold water installations Polyethylene of raised temperature resistance (PE-RT); ISO 17484, Plastics piping systems Multilayer pipe systems for indoor gas installations with a maximum operating pressure up to and including 5 bar (500 kPa).

34、 Fittings may be suitable for joining other pipes provided the fitting joint with the specified pipe meets the requirements of this European Standard and the relevant pipe standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and a
