Wood-based panels for use in construction - Characteristics, evaluation of conformity and marking
This European Standard defines wood-based panels for use in construction and specifies relevant characteristics and appropriate test methods to determine those characteristics for wood-based panels, whether unfaced, overlaid, veneered or coated:
a) for internal use as structural components in dry conditions );
b) for internal (or protected external) use as structural components in humid conditions );
c) for external use as structural components );
d) for internal use as non-structural components in dry conditions1);
e) for internal (or protected external) uses as non-structural components in humid conditions2);
f) for external use as non-structural components3);
g) for use as structural floor decking on joists in dry1) or humid2) or external3) conditions;
h) for use as structural roof decking on joists in dry1) or humid2) or external3) conditions;
i) for use as structural wall sheathing on studs in dry1) or humid2) or external3) conditions.
This European Standard covers wood-based panels in the form of solid wood panels, LVL ), plywood, OSB, particleboards (chipboards, flaxboards) either resin- or cement-bonded, wet process fibreboards (hardboards, medium boards, softboards) and dry process fibreboards (MDF) for use in construction.
This European Standard includes provisions for evaluation of conformity and marking of wood-based panels.
The wood-based panels may be treated during production with chemical agents to improve their reaction to fire performance and/or their resistance to biological attack, e.g. by fungi and insects. However, the processes of such treatments are outside the scope of this European standard.
This European Standard is not intended to be applicable to wood-based panels for use in non-constructional applications.

This document is currently submitted to the Unique Acceptance Procedure. This document will supersede EN 13986:2004. This document has been prepared under Mandate M/113, as amended, given to CEN by the European Commission and the European Free Trade association and supports essential requirements of EU Directives. Self-supporting building elements (without additional carrying system behind) are not covered by this standard. For relationship with Council Directive 89/106/EEC, see informative Annex ZA, which is an integral part of this document. Compared with EN 13986:2004 the following modifications have been made: a) in Clause 4, the requirements for the determination of performance characteristics are stated more clearly, and additional performance characteristics that may be required for some panel applications have been included; b) provisions for marking and documentation in Clause 7 are made consistent with the marking and documentary requirements for CE marking in informative Annex ZA; c) provisions of ZA.3 regarding the location of the CE marking and its accompanying information are amended; d) responsibilities of the consignees of wood-based panels are introduced into the document as Clause 8; e) flaxboards and extruded particleboards have been taken into account; f) Table 8 for classification of reaction to fire performance without further testing (CWFT) extended; g) frost resistance for cement bonded particleboards and embedment strength added as performance characteristics for certain applications in Clause 4; h) embedment strength and air permeability have been taken into account in accordance with amendment of Mandate M 113; i) in Annex B for formaldehyde gas analysis values for all board types introduced and upper limit E2-values added for chamber method and adapted for perforator method. kSIST FprEN 13986:2010
