BRITISH STANDARDWood-based panels for use in construction — Characteristics, evaluation of conformity and marking The European Standard EN 13986:2004 has the status of a British Standard ICS 83.140.99 12&23<,1*:,7+287%6,3(50,66,21(;&(37$63(50,77('%<&23<5,*+7/$: BS EN 13986:2004 BS EN 13986:2004 National foreword This British Standard is the official English language version of EN 13986:2004. It supersedes BS EN 13986:2002 which is withdrawn.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: — aid enquirers to understand the text; — present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; — monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references The British Standards which implement international or European publications referred to in this document may be found in the BSI Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Search” facility of the BSI Electronic Catalogue or of British Standards Online. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. This British Standard was published under the authority of the Standards Policy and Strategy Committee on 21 April 2005 Summary of pages This document comprises a front cover, an inside front cover, the EN title page, pages 2 to 57 and a back cover.
