EN 383:2007 (E) 3 Foreword This document (EN 383:2007) 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of an identical text or by endorsement, at the latest by July 2007, and conflicting national standards shall be withdrawn at the latest by July 2007. This document supersedes EN 383:1993. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, 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 383:2007 (E) 4 1 Scope This standard specifies laboratory methods to determine the embedding strength and foundation values of solid timber, glued laminated timber and wood based sheet products with dowel type fasteners.
2 Normative references Not applicable. 3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply.
3.1 dowel type fastener bolt, nail, dowel or the like with plain or patterned surfaces
3.2 embedment strength average compressive stress at maximum load in a piece of timber or wood based sheet product under the action of a stiff linear fastener. The fastener's axis is perpendicular to the surface of the timber. The fastener is loaded perpendicular to its axis
3.3 maximum load
maximum load measured before the deformation of the specimen has reached the deformation limit
3.4 fastener section dimension
1) Nominal diameter of round fasteners; or
2) Length of one side of the section of a square fastener; or
3) Minimum dimension of the section of an oval or rectangular fastener.
