5 NEN-EN :2016 EN :2016 (E) European foreword This document (EN :2016) has been prepared by Technical Committee CEN/TC 185 "Fasteners", the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2017, and conflicting national standards shall be withdrawn at the latest by April Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN :2007. 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. EN consists of the following parts, under the general title Non-preloaded structural bolting assemblies: Part 1: General requirements; Part 2: Fitness for purpose. Compared to the previous version, the modifications are the following: the standard was revised to meet the new format for harmonized standards and in relation to the Regulation (EU) No. 305/2011 (CPR); the requirements of this standard only relate to the product characteristics of bolting assemblies which are necessary for CE marking; all clauses dealing with further technical or other requirements have been transferred to EN ; washers are not considered as part of the non-preloaded bolting assemblies, however they can be used as relevant; addition of bolting assemblies made in aluminum and aluminum alloys; addition of nominal diameters M5 to M10; Railway rail fasteners have been excluded. 3

6 EN :2016 (E) NEN-EN :2016 According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. 4

7 NEN-EN :2016 EN :2016 (E) Introduction Rules for design and execution of bolted connections with non-preloaded structural bolts are defined for instance in EN and EN for steel structures or EN and EN 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 f ub A s. For this purpose the tensile test of bolting assemblies specified in EN is a mean to check whether the function of the assembly is fulfilled. Washers or other elements can be used additionally if necessary. 5

8 EN :2016 (E) NEN-EN : Scope This part of this European Standard specifies the general requirements for bolting assemblies for nonpreloaded 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 or 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 or 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 ); nuts made of austenitic stainless steel: 50, 70, 80 (in accordance with EN ISO ); 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 , and from M5 to M39 for use in aluminium or aluminium alloy structures according to EN 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 , 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 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 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.
