DIN EN 15048-2:2016-09 EN 15048-2:2016 (E) 4 Introduction This Eu

24、ropean Standard specifies the requirements to ensure that non preloaded structural bolting assemblies (bolts + nuts) are fit for purpose in structural metallic works. Structural bolting assemblies which meet the requirements of this European Standard have been designed to allow tensile loading of at

25、 least fub As. Since the tensile resistance of bolting assemblies is very sensitive to differences in manufacture, it is important that the bolting assemblies are supplied by one manufacturer who is always responsible for the function of the bolting assembly. For the same reason it is important that

26、 the coating of the bolting assemblies is under the control of the manufacturer. DIN EN 15048-2:2016-09 EN 15048-2:2016 (E) 5 1 Scope This European Standard specifies the technical requirements for structural bolting assemblies in order to ensure the suitability for non-preloaded bolted connections

27、in steel structures or aluminium structures. A suitability test is specified to check the behaviour of the structural bolting assemblies. It applies to bolting assemblies specified in EN 15048-1. 2 Normative references The following documents, in whole or in part, are normatively referenced in this

28、document and are indispensable for its application. For dated references, only the edition cited applies.

37、ssemblies The performance of structural bolting assemblies depends on the properties of their specific components. Therefore, the essential characteristics listed in EN 15048-1 are assessed through the verification of the properties of the involved components and/or bolting assemblies, as applicable

38、. Other aspects dealing with marking and delivery conditions are assessed through inspection of the involved components and/or bolting assemblies, as applicable. 5.2 Product requirements Dimensions, tolerances on dimensions, form and position shall be in accordance with the relevant product standard

39、s. Components of structural bolting assemblies shall be selected by the manufacturer with the following priority order. a) General reference to published EN standards: For hexagon components, the following standards shall apply: 1) EN ISO 4014, EN ISO 4017, EN ISO 4032 and EN ISO 4033 for hexagon pr

40、oducts of product grades A and B; 2) EN ISO 4016, EN ISO 4018 and EN ISO 4034 for hexagon products of product grade C; 3) when required, prevailing torque nuts in accordance with EN ISO 2320 and EN ISO 7040, ISO 7041, EN ISO 7042 or EN ISO 7719 may be used.
