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.

41、 7 b) General reference to ETAs, c) General reference to published ISO standards, d) When none of these standards/ETAs exist, then reference to national standards is permitted. Any suitable head shape, shank dimension, thread length, etc. may be used provided that all requirements of EN 15048-1 and
42、EN 15048-2 are met. NOTE Additional requirements for design and/or execution are defined for instance in EN 19931-8, and EN 10902 for steel structures or EN 10903 for aluminium structures. If washers are specified for use with non-preloaded structural bolting assemblies, washers of product grade A o
