BS EN 14592:2008+A1:2012 EN 14592:2008+A1:2012 (E)5 1 Scope This European Standard specifies the requirements and test methods for materials, geometry, strength, stiffness and durability ascpects (i.e. corrosion protection) of dowel-type

23、 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

24、 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

25、 Standard covers fasteners that may be coated for the following purposes: 1 Corrosion protection (e.g. hot dip galvanization, epoxy coating); 2 Lubricants (to facilitate insertion); 3 Withdrawal enhancement and/or collation (adhesive coating).“ 2 Normative references The following referenced documen
