DIN EN 14592:2012-07

This European Standard specifies the requirements and test methods for materials, geometry, strength, stiffness and durability aspects (that is, corrosion protection) of dowel-type fasteners for use in load bearing timber structures. Only dowel-type fasteners manufactured from steel are covered by this European Standard. For the purpose of this standard, dowel-type fasteners for timber structures are taken to be nails, staples, screws, dowels, and bolts with nuts. Definitions of these items are given in clause 3. This European Standard specifies also the evaluation of conformity procedures and includes requirements for marking of these products. This European Standard does not cover fasteners treated with fire retardants to improve their fire performance. This European Standard covers fasteners that may be coated for the following purposes: 1 corrosion protection (for example, hot dip galvanization, epoxy coating); 2 lubricants (to facilitate insertion); 3 withdrawal enhancement and/or collation (adhesive coating). This document (EN 14592:2008+A1:2012) has been prepared by Technical Committee CEN/TC 124 "Timber structures", the secretariat of which is held by AFNOR (France). The responsible German committee is Working Committee NA 005-04-01 AA "Holzbau" (Spiegelausschuss von CEN/TC 124, CEN/TC 250/SC 5) ("Timber structures" (Mirror Committee of CEN/TC 124, CEN/TC 250/SC 5)) at DIN, the German Institute for Standardization e. V. This standard differs from DIN EN 14592:2009-02 as follows: a) the scope has been extended to cover coated or otherwise treated fasteners; b) normative references have been updated; c) the materials for nails, staples, screws and dowels have been changed; d) specifications relating to the geometry and corrosion protection of nails, staples, screws and dowels have been changed; e) specifications in Tables 2 to 11 have been expanded; f) Annex B has been deleted (specifications are now given in prEN 16351:2011); g) Annex ZA has been updated and specifications for fasteners with coating have been aligned.
