This European Standard shall be gi

This document has been prepared under a mandate given to CEN by the European Commis

For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. According to the CEN/CENELEC Internal Regulations, the national standards organizations o

18、h structural bolts respectively are defined for instance in EN 1993-1-8 (Eurocode 3) and prEN 1090-2. The parts of this European Standard on structural bolting specify the general requirements which ensure that bolt/nut/washer assemblies are suitable for use in non preloaded structural bolting. They
19、 can be used in shear con-nections and/or in tension connections if no preload is required. Structural fasteners which meet the requirements of this part of this European Standard have been designed to allow tensile loading of at least fub Asas defined in EN 1993-1-8. Structural fasteners which meet
20、 the requirements of EN 14399-1 are suitable for use in preloaded and non-preloaded structural bolting. This European Standard deals with structural fasteners which are intended for use as non-preloaded assemblies. Since the tensile resistance of bolt/nut assemblies is very sensitive to differences
21、in manufacture, it is important that the assemblies are supplied by one manufacturer who is always responsible for the function of the assembly. For the same reason it is important that coating of the assemblies is under the control of one manufacturer. Beside the mechanical properties of the compon
22、ents the functionality of the assembly requires that the required tensile resistance is achieved. For this purpose the tensile test of assemblies is a means to check whether the func-tion of the assembly is fulfilled.

23、led Copy, (c) BSIEN 15048-1:2007 (E) 5 1 Scope This part of this European Standard specifies the general requirements for the components of bolt/nut/washer assemblies for non-preloaded structural bolting and for the assemblies themselves. It applies to bolts (including screws, studs and stud bolts)
24、and nuts made of carbon steel, alloy steel and stainless steel with the following property classes: bolts made of carbon steel and alloy steel: 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 10.9; nuts made of carbon steel and alloy steel: 4, 5, 6, 8, 10, 12; bolts made of austenitic stainless steel: 50, 70, 80; nut
25、s made of austenitic stainless steel: 50, 70, 80; if appropriate, washers according to hardness class HV 100 or HV 200. NOTE The property classes 4.8, 5.8 and 6.8 may be subjected to limitations of use, it is recommended to refer to prEN 1090-2. The standard applies to thread sizes from M12 to M36 a
26、nd to the associated washers but does not preclude the use of other sizes. Bolted connections with components according to this European Standard are able to be shear and/or tensile loaded. Bolts, nuts and washers according to this European Standard are not normally intended for welding. 2 Normative
