EN 1254-6:2012 (E) 6 Introduction Products complying with this document may be used for the transport of water for human consumption if they comply with the relevant national, regional or local regulatory provisions applicable in the place of use. This European Standard provides the basis for the assessment of a manufacturer's production process for products manufactured in accordance with this European Standard. SIST EN 1254-6:2014
EN 1254-6:2012 (E) 7 1 Scope This European Standard specifies materials and test requirements for fittings of copper and copper alloys. This part of EN 1254 specifies push-fit end connections with or without plating or coating in the size range 6 mm to 54 mm for the purpose of joining tubes of copper, plated copper, multilayer pipes and plastics pipes, intended 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. Permissible operating temperatures and maximum operating pressures are also established. 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 being conveyed. The standard establishes a designation system for the fittings. This European Standard is applicable to push-fit fittings for joining one or more of the following tubes or pipes: Copper tubes to EN 1057; PE-X pipes to EN ISO 15875-2; PB pipes to EN ISO 15876-2; PP pipes to EN ISO 15874-2; PE-RT pipes to EN ISO 22391-2; Multilayer pipes to EN ISO 21003-2. Fittings may be suitable for joining other tubes and pipes provided the push-fit joint with the specified tube or pipe meets the requirements of this standard. Operating temperatures and pressures For joints with copper tubes It is essential that operating temperatures and maximum operating pressures for assembled joints do not exceed the values in Table 1. Table 1 — Operating temperatures and pressures for fittings assembled to tubes Operating temperature Maximum operating pressure (MOP) for nominal diameters from 6 mm up to and including 54 mm °C bar 30 16 95
6 Intermediate pressure ratings are determined by linear interpolation. Certain designs of push-fit fittings are suitable for use at temperature/pressure ratings outside those given in this table. For such applications, the advice of the manufacturer should be sought. To allow for system malfunctions, it is essential that fittings be capable of temporary excursions up to a temperature of 110 °C at a pressure of 6 bar. SIST EN 1254-6:2014
EN 1254-6:2012 (E) 8 For joints with multilayer and plastics pipes The operating temperatures and maximum operating pressures for the assembled joints should be determined in accordance with multilayer or plastics pipe material properties, details of which are specified in the relevant multilayer and plastics piping system standards. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
