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of an identical text or by endorsement, at the latest by December 2020, and conflicting national standards shall be withdrawn at the latest by December 2020. This document supersedes EN 6361:1996, EN 6362:1996 and EN 6363:1996. Compared to EN 6361:1996, EN 6362:1996 and EN 6363:1996 the following modifications have been made: a) a classification system for bending strength and bending modulus has been added. b) the classification of formaldehyde release has been revised in accordance with EN 13986. Annex A is normative. According to the CEN/CENELEC Internal Regulations, the national standards anizations of the following coun tries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom. 1 Scope This European Standard specifies the requirements for plywood for general purposes or structural application in dry, humid or exterior conditions. It also gives a classification system based on the bending properties. NOTE 1 This standard will be called up in EN 13986 for construction applications. The values listed in this standard relate to product properties but they are not characteristic values to be used in design calculations. NOTE 2 Such characteristic values (e. g. for use in design calculation in ENV 199511) are given either in prEN 123692 or by the manufacturer, based on testing according to EN 789, EN 1058 and ENV 1156. Additional information on supplementary properties for certain applications is also given. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).
