16、This European Standard (EN 1515-3:2005) 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 th

17、e latest by March 2006, and conflicting national standards shall be withdrawn at the latest by March 2006.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

18、 of bolt materials for steel flanges, Class designated.

24、3506-1:1997). 3 Classification of bolt materials The classification of bolt materials as given in Table 1 is based on the rules given in ASME B16.5 (see also annex A). All bolting materials are subject to the following limitations: a) High strength bolting (allowable stress 170 N/mm2 and above; see

25、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, provided the ability according to EN 1759-1:2004, 5.3.1 is verified. c) Low

26、 strength bolting (allowable stress 140 N/mm2 and 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. Licensed Copy: Institute Of Technology Tallaght, Institute of Technology, Mon Apr 02

32、strength is classified with an allowable stress of 170 N/mm2 and higher, low strength with 140 N/mm2 and lower. If an EN-material has an equivalent ASTM material according to EN 1515-1, the classification according to B16.5 shall govern (see line 14, 21 and 23). Table A.1 Development of bolting clas
