15、cal 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 2006, and conflicting national standards shall be

16、 withdrawn at the latest by March 2006. EN 1515 “Flanges and their joints Bolting“ consists of three Parts: Part 1: Selection of bolting; Part 2: Classification of bolt materials for steel flanges, PN designated; Part 3: Classification of bolt materials for steel flanges, Class designated. According

17、 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, Den-mark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,

18、 Luxem-bourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 1515-3:2005 (E) 4 1 Scope This European Standard covers the classification of bolt materials used in combination with steel flanges ac-cording to EN 1759-1 (Class designa

19、ted). Bolt materials are listed in EN 1515-1; flange material groups are listed in EN 1759-1. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the l

All bolting materials are subject to the following limitat

23、ions: a) High strength bolting (allowable stress 170 N/mm2and above; see Table A.1) may be used in any flanged joint. During assembly however, care should be taken not to over-stress the flanges (e. g. by means of torque control). b) Intermediate strength bolting may be used in any flanged joint, pr

24、ovided the ability according to EN 1759-1:2004, 5.3.1 is verified. c) Low strength bolting (allowable stress 140 N/mm2and below; see Table A.1) is restricted to CL 150 and CL 300. The ability according to EN 1759-1:2004, 5.3.1 shall be verified, with special consideration of the gasket. EN 1515-3:20
