It supersedes BS EN 13986:2002 which is withdrawn. EN 13986 is a “ harmonized” European Standard and fully takes into account the requirements of the European Commission mandate M/113, Wood-based panels, given under the EU Construction Products Directive (89/106/EEC), and is intended to lead to CE marking. The UK participation in its preparation was entrusted to Technical Committee B/541, Wood-based panels, which has the responsibility to: A list of organizations represented on this committee can be obtained on request to its secretary.

EN 13986:2004 (E) 4 Foreword This document (EN 13986:2004) has been prepared by Technical Committee CEN/TC 112 “Wood-based panels”, the secretariat of which is held by DIN. 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of an identical text or by endorsement, at the latest by April 2005, and conflicting national standards shall be withdrawn at the latest by April 2005. This document has been prepared under Mandate M/113 given to CEN by the European Commission and the European Free Trade Association, as revised by the Standing Committee on Construction on 14 May 2003 and supports essential requirements of EU Directives. For relationship with Council Directive 89/106/EEC, see the informative Annex ZA, which is an integral part of this document. This document supersedes EN 13986:2002. Compared to EN 13986:2002 the following modifications have been made: a) Addendum to Mandate M 113 concerning release of formaldehyde for external use has been taken into account in Tables 3 and 6. b) Revisions of specifications for particleboard in EN 312, for plywood in EN 636 and for MDF in prEN 622-5 have been taken into account. c) Laminated Veneer Lumber (LVL) has been included in Tables 1 to 7. d) Additional clarification has been added in 6.2 for factory production control and in 6.3 for initial type testing. e) Provisions for marking in Clause 7 are described more clearly. f) Annex ZA has been revised in accordance with the new format of presentation. 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, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. ? EN 13986:2004 (E) 5 1 Scope This document defines wood-based panels for use in construction and specifies the relevant characteristics and the appropriate test methods to determine these characteristics for wood-based panels, unfaced, overlaid, veneered or coated: for internal use as structural components in dry conditions1) ; for internal (or protected external) use as structural components in humid conditions2) ; for external use as structural components3) ; for internal use as non-structural components in dry conditions1); for internal (or protected external) uses as non structural components in humid conditions2); for external use as non-structural components3); for use as structural floor decking on joists in dry1) or humid2) or external3)conditions; for use as structural roof decking on joists in dry1) or humid2) or external3)conditions; for use as structural wall sheathing on studs in dry1) or humid2) or external3)conditions. It provides for the evaluation of conformity and the requirements for marking these products. This document covers wood-based panels in the form of solid wood panels, LVL4) , plywood, OSB, particleboards (chipboards) either resin- or cement-bonded, wet process fibreboards (hardboards, medium boards, softboards) and dry process fibreboards (MDF) for use in construction. They may contain chemical agents to improve their reaction to fire and their resistance to biological attack, e.g. by fungi and insects. This document is not intended to be applicable to wood-based panels for use in non-constructional applications. 2 Normative references The following referenced documents are indispensable for the application of this document.
