3、dThis British Standard is the official English language version of EN 14399-1:2005.EN 14339-1:2005 is a candidate “harmonized” European Standard and fully takes into account the requirements of the European Commission mandate M/120, Structural metallic products and ancillaries, given under the EU Co
4、nstruction Products Directive (89/106/EEC), and is intended to lead to CE marking. The date of applicability of EN 14399-1:2005 as a harmonized European Standard, i.e. the date after which this standard may be used for CE marking purposes, is subject to an announcement in the Official Journal of the
5、 European Communities.The Commission in consultation with Member States has agreed a transition period for the co-existence of harmonized European Standards and their corresponding national standard(s). It is intended that this period will comprise a period, usually nine months, after the date of av
6、ailability of the European Standard, during which any required changes to national regulations are to be made, followed by a further period, usually of 12 months, for the implementation of CE marking. In this instance an application has been made to CEN for a two-year extended co-existence period, f
7、rom September 2005 to September 20071). At the end of the co-existence period, the national standard(s) will be declared obsolescent, and will be withdrawn on publication of Eurocode 3.EN 14399-1:2005 is the subject of transitional arrangements agreed under the Commission mandate. In the UK, the cor
8、responding national standards are: BS 4395-1:1969, Specification for high strength friction grip bolts and associated nuts and washers for structural engineering Part 1: General grade; BS 4395-2:1969, Specification for high strength friction grip bolts and associated nuts and washers for structural
9、engineering Part 2: Higher grade bolts and nuts and general trade washers2);and based on the applied-for transition period, it is planned that BS 4395-1:1969 and BS 4395-2:1969 will be declared obsolescent in September 20071), and then, together with BS 449 and BS 5950, will be withdrawn upon public
10、ation of Eurocode 3. BS 4395-1:1969 and BS 4395-2:1969 currently support BS 449 and BS 5950.NOTE This date is approximate.

EN 14399-1:2005 (E) 4 Introduction This document on structural bolting reflects the situation in Europe where two technical solutions exist to achieve the necessary ductility of bolt/nut/washer assemblies. These solutions utilize different syst
30、ems (HR and HV) of bolt/nut/washer assemblies, see Table 1. Both systems are well proved and it is up to the experts responsible for structural bolting whether they use the one or the other system. It is, however, important for the performance of the assembly to avoid mixing up the components of bot
31、h systems. Therefore, the bolts and nuts for both systems are standardized in one single part of this European Standard each and the marking of the components of the same system is uniform.

33、tive to differences in manufacture and lubrication. Therefore it is important that the assembly is 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 assembly is under the control of one manufacturer. Besid
34、e the mechanical properties of the components the functionality of the assembly requires that the specified preload can be achieved if the assembly is tightened with a suitable procedure. For this purpose a test method for the suitability of the components for preloading was created which will demon
35、strate whether the function of the assembly is fulfilled. For the time being, the product standards EN 14399-3 to EN 14399-6 are the only European Standards which have regard to the general requirements of EN 14399-1. However, further product standards on fit bolts, countersunk head bolts, and load
36、indicating washers for the use in high strength structural bolting for preloading are under preparation. EN 14399-1:2005 (E) 5 1 Scope This document specifies the general requirements for the components of bolt/nut/washer(s) assemblies for high-strength structural bolting, which are suitable for pre
37、loading, and for the assemblies themselves. Examples for components which fulfil the requirements of this document are specified in EN 14399-3, EN 14399-4, EN 14399-5 and EN 14399-6. NOTE For clauses of this document addressing the provisions of the EU Construction Products Directive, see Annex ZA.
