Attention is drawn to the possibility that some of the elements of this document may be the subject of patent righ
9、ts. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EC Directive(s). For relationshi
10、p with EC Directive(s), see informative Annex ZA, which is an integral part of this document.

12、an Standard specifies the requirements and test methods for materials, geometry, strength, stiffness and durability ascpects (i.e. 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 S
13、tandard. 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 requ
14、irements for marking of these products. This European Standard does not cover resin coated dowel-type fasteners and fasterners treated with fire retardants to improve their fire performance. It also does not cover resin coated fasteners. 2 Normative references The following referenced documents are
