24、:2015EN 14399-1:2015 (E) 5 Introduction This document on structural bolting assemblies reflects the situation in Europe where two technical solutions exist to achieve the necessary ductility of bolting assemblies. These solutions utilize different bolting assemblies (system HR, HV and HRC). Both sys

25、tems are well proven and it is the responsibility of the experts for structural connections whether they use the one or the other system. It is however important for the performance of the bolting assembly to avoid mixing up the components of both systems. Therefore, the bolts and nuts for both syst

26、ems are standardized in one single part of this European Standard each and the marking of the components of the same system is consistent. BS EN 14399-1:2015EN 14399-1:2015 (E) 6 1 Scope This European Standard specifies the general requirements for bolt/nut/washer(s) assemblies for high-strength str

27、uctural bolting, which are suitable for preloading. The intended use of bolting assemblies in accordance with this European Standard is structural metallic works. NOTE 1 High-strength structural bolting assemblies in accordance with EN 14399-2 to EN 14399-10 are designed to fulfil the requirements o

28、f this European Standard. NOTE 2 High-strength structural bolting assemblies are suitable for preloading in accordance with EN 1090-2 in steel structures. High-strength structural bolting assemblies smaller than M12 are not designed to be preloaded. High-strength structural bolting assemblies are no

29、t designed to be welded. Railway rail fasteners are not covered by this standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

40、of this document, the terms and definitions given in EN 1090-2:2008+A1:2011 and the following apply. 3.1 bolting assembly matching bolt, nut, washer(s) and if relevant, direct tension indicator and nut face washer or bolt face washer 3.2 single bolting assembly lot bolting assembly lot containing: b

43、t having the main influence (either nut or direct tension indicator) is determined on the basis of test results. Note 2 to entry: An extended bolting assembly lot contains bolts, nuts and washers and, if relevant, direct tension indicators and nut face washers or bolt face washers. 3.4 manufacturing

44、 lot (for bolting assemblies components) quantity of components of a single designation including product grade, property class, type, and size, manufactured from bar, wire, rod or flat product from a single cast, processed through the same or similar steps at the same time or over a continuous time

45、 period, through the same heat treatment, coating and/or lubrication process, if any Note 1 to entry: Same process means: for a continuous process, the same treatment cycle without any setting modification; for a discontinuous process, the same treatment cycle for identical consecutive loads (batche

46、s). Note 2 to entry: The manufacturing lot may be split into a number of manufacturing batches for processing purposes and then re-assembled into the same manufacturing lot. 4 Product characteristics 4.1 General The performance of the high-strength structural bolting assemblies depends on the type o

47、f the bolting assemblies and on properties of their specific components (bolts, nuts, washers, and direct tension indicators if provided). Therefore, the requirements specified in 4.2 to 4.5 are assessed through the verification of the properties of the involved components and/or bolting assemblies,

48、 as applicable. 4.2 Type (bolting assemblies) 4.2.1 General Type covers the axial load expected from design and margin against overtightening. The Type is relevant for the ability of the bolting assembly to be tightened by different tightening methods given in EN 1090-2 in order to provide the decla

49、red performances of the bolting assemblies. There are two types of bolting assemblies: Type HR (systems HR with or without direct tension indicators, if provided, and HRC) designed to obtain ductility predominantly by plastic elongation of the bolt (minimum nut height 0,9 D and thread length of the bolt according to ISO 888); Type HV (system HV with or without direct tension indicators, if provided) designed to obtain ductility predominantly by plastic deformation of the engaged threads (nut height at approx
