figures were replaced. This document EN 1759-32003 has been prepared by Technical Committee CEN /TC 74, “Flanges and their joints“ 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of an identical text or by endorsement, at the latest by March 2004, and conflicting national standards shall be withdrawn at the latest by March 2004. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of the Pressure Equipment Directive PED1. For relationship with EU Directives, see inative annex ZA, which is an integral part of this standard. EN 1759 consists of the following parts  Part 1 Steel flanges draft stage;  Part 3 Copper alloy flanges draft stage;  Part 4 Aluminium alloy flanges draft stage. The anns A, B, C, D and ZA are inative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom. Introduction This standard is related, but not identical, to IS0 7005-3 in respect of flanges having designations Class 150 and Class 300. Outside diameters and mating dimensions are in accordance with ANSI B16.24. Ination on the use of metric bolting in lieu of imperial bolting which can be used with these flanges is given in an inative annex. The mating dimensions of the flanges of this standard are compatible with Class designated flanges of other materials in accordance with the other parts of EN 1759. 1 Directive 97/23 EC of the European Parliament and of the Council of 29 May 1997 on the approximation of the Laws of the Member States concerning pressure equipment; OIEC L 181.

This standard also specifies dimensions and tolerances, materials and their associated pressure/temperature p/T ratings, flange facings and related surface finish, weld repairs and marking together with ination on bolting, gaskets, application and installation and approximate flange masses. The flanges specified, with the exception of integral type 21 flanges, are for attachment to copper or copper alloy tubes in accordance with EN 12449. NOTE 1The size of copper and copper alloy tubes is designated by reference to the outside diameter in millimetres. NOTE 2See also annex B. NOTE 3Non-gasketed pipe joints are outside the scope of this standard.
