EN 1380:2009 (E) 3 Foreword This document (EN 1380:2009) has been prepared by Technical Committee CEN/TC 124 “Timber structures”, the secretariat of which is held by SFS. 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of an identical text or by endorsement, at the latest by October 2009, and conflicting national standards shall be withdrawn at the latest by October 2009. This document supersedes EN 1380:1999. The first version of this European Standard was published in September 1999 and considered only connections with nails. When the product standard for dowel type fasteners EN 14592 became available the scope of EN 1380 was expanded. Therefore, this revised version covers dowel type fasteners as nails, screws, dowels and bolts. Connections with load bearing staples are considered in EN 1381:1999. 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, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

EN 1380:2009 (E) 4 1 Scope This European Standard specifies test methods for determining the strength and deformation characteristics of laterally loaded connections with nail, screws, dowels and bolts in load-bearing timber structures. The methods assess connections with members of timber (solid timber or glued laminated timber) or wood-based products or metal plates (but not punched metal plate fasteners) in the combination proposed for use in service. The methods are used to determine load-slip characteristics and maximum load of connections where various angles between the applied force and the timber grain direction, or the main direction of the wood-based products, respectively, are possible. 2 Normative references The following referenced documents are indispensable for the application of this document.

3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 deformation of the connection mean value of the measurements of the relative displacements of the members 3.2 dowel type fasteners elements such as nails, screws, dowels and bolts as defined by EN 14592 4 Symbols and abbreviations For the purposes of this document, the following symbols and abbreviations apply. b
width of member cross-section, in millimetres F load, in newtons t member thickness, in millimetres 5 Requirements 5.1 Timber The timber (solid timber or glued laminated timber) shall satisfy the requirements of EN 14080, EN 14081-1 and shall be selected in accordance with either of the methods given in EN 28970. For each test piece, the individual members to be joined shall be selected to ensure a test piece of balanced density. For a group of similar test pieces, separate planks shall be used for each test piece. NOTE The members should be free from major defects, which could lead to premature failure in the area away from the fasteners. 5.2 Wood-based products The specification of the wood based products shall be established.
