This document is currently submitted to the Unique Acceptance Procedure. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports basic work requirements of Regulation (EU) No 305/2011. For relationship with Regulation (EU) No 305/2011 see informative Annex ZA, which is an integral part of this document. NOTE Due to fact that the Framework Partnership Agreement between the Commission and CEN & CENELEC is not signed yet, there are currently no New Approach Consultants in place for 2014. Therefore the provisions of CEN-CENELEC Guide 15 cannot be met. This shall not prevent the processing of draft standards nor the offering of harmonized standards to the Commission. In particular, draft standards can be sent to vote without Consultant assessment. This note will be removed from the Foreword of the finalized publication.

This document will supersede EN 15048-1:2007. EN 15048 consists of the following parts, under the general title Non-preloaded structural bolting assemblies: — Part 1: General requirements; — Part 2: Fitness for purpose. kSIST FprEN 15048-1:2014

FprEN 15048-1:2014 (E) 4 Introduction Rules for design and execution of bolted connections with non-preloaded structural bolts are defined for instance in EN 1993-1-8 and EN 1090-2 for steel structures or EN 1999-1-1 and EN 1090-3 for aluminium or aluminium alloy structures. The parts of this European Standard on structural bolting assemblies specify the general requirements which ensure that bolting assemblies comprising bolts and nuts are suitable for use as non-preloaded structural bolting in structural metallic works. They can be used in shear connections and/or in tension connections if no preload is required. Structural bolting assemblies which meet the requirements of this part of this European Standard have been designed to allow tensile resistance of at least fub

× As. For this purpose the tensile test of bolting assemblies specified in EN 15048-2 is a mean to check whether the function of the assembly is fulfilled. kSIST FprEN 15048-1:2014

FprEN 15048-1:2014 (E) 5 1 Scope This part of this European Standard specifies the general requirements for bolting assemblies for non-preloaded structural bolting. Bolting assemblies in accordance with this European Standard are designed to be used in structural bolting connections for shear and/or tensile loading. The intended use of bolting assemblies in accordance with this European standard is structural metallic works. It applies to bolts (the term used when bolts partially threaded, screws, studs and stud-bolts are considered all together) and nuts made of carbon steel, alloy steel, stainless steel or aluminium or aluminium alloy 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 (in accordance with EN ISO 898-1); — nuts made of carbon steel and alloy steel: 5, 6, 8, 10, 12 (in accordance with EN ISO 898-2); — bolts made of austenitic stainless steel: 50, 70, 80 (in accordance with EN ISO 3506-1); — nuts made of austenitic stainless steel: 50, 70, 80 (in accordance with EN ISO 3506-2); — bolts made of aluminium or aluminium alloy: AL1 to AL6 (in accordance with EN 28839); — nuts made of aluminium or aluminium alloy: AL1 to AL6 (in accordance with EN 28839). This European Standard applies to bolting assemblies with ISO metric coarse pitch thread from sizes M12 to M39 for use in steel structures according to EN 1090-2, and from M5 to M39 for use in aluminium or aluminium alloy structures according to EN 1090-3. The use of thread sizes larger than M39 is not precluded provided all applicable requirements of this standard are met. WARNING — Only bolting assemblies are covered by this harmonized standard: separate bolts or nuts, not tested as part of an assembly lot of bolting assemblies in accordance with EN 15048-2, are not covered by this harmonized standard and cannot be CE marked. NOTE 1 The property classes 4.8, 5.8 and 6.8 may be subjected to limitations of use. NOTE 2 High-strength structural bolting assemblies for preloading which meet the requirements of EN 14399–1 are not within the scope of this European Standard but they are also suitable for use in non-preloaded structural bolting. NOTE 3 Bolts and nuts made of aluminium or aluminium alloys are not designed to be used in steel structures, see EN 1090–2. Bolting assemblies in accordance with this European Standard are not designed to be welded. Railway rail fasteners are not covered by this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
