Plywood - Specifications

This European Standard specifies the requirements for plywood, as defined in EN 313 2, for both general purpose use (non-structural application) and structural application in dry, humid or exterior conditions. It also gives a classification system based on the bending properties.
NOTE 1   This European Standard is referenced in EN 13986 for construction applications.
This standard can be appropriately applied for all plywood, including overlaid and coated plywood, but it does not cover materials or processes used for overlaying or coating. Neither does it cover any materials or processes applied in relation to enhancement of biological durability.
NOTE 2   For additional guidance on biological durability and the potential need for preservative treatment, according to application and serviceability, reference can be made to CEN/TS 1099.
The values listed under Clause 4 relate only to product properties; they are not 'characteristic values' and are not to be used in design calculations.
NOTE 3   Characteristic values (i.e. for use in design calculation according to EN 1995–1-1) are given either in EN 12369–2 which is based on the classification system given in this standard 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.

Foreword
This document (EN 636:2012/FprA1:2014) has been prepared by Technical Committee CEN/TC 112 “Wood-
based panels”, the secretariat of which is held by DIN.
This document is currently submitted to the Unique Acceptance Procedure.
1 Modification to Clause 1, Scope
Replace the text of the scope by the following one:
This European Standard specifies the requirements for plywood, as defined in EN 313-2, for both general
purpose use (non-structural application) and structural application in dry, humid or exterior conditions. It also
gives a classification system based on the bending properties.
NOTE 1 This European Standard is referenced in EN 13986 for construction applications.
This standard can be appropriately applied for all plywood, including overlaid and coated plywood, but it does
not cover materials or processes used for overlaying or coating. Neither does it cover any materials or
processes applied in relation to enhancement of biological durability.
NOTE 2 For additional guidance on biological durability and the potential need for preservative treatment, according to
application and serviceability, reference can be made to CEN/TS 1099.
The values listed under Clause 4 relate only to product properties; they are not 'characteristic values' and are
not to be used in design calculations.
NOTE 3 Characteristic values (i.e. for use in design calculation according to EN 1995–1-1) are given either in
EN 12369–2 which is based on the classification system given in this standard 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 Modification in 12.1, Boards marketed within the European Economic area for
construction applications
Replace the existing text by the following one:
Boards produced in conformity with this European Standard and marketed in any of the territories of the EEA
for use in construction as defined in the Construction Products Regulation (n°305/2011) shall be marked
according to the requirements of EN 13986.
Complementary, each board or package shall be clearly marked by the manufacturer by indelible direct
printing with the following information:
- the number of this European standard (EN 636) and the conditions of use (−1 for use in dry conditions, −2
for use in humid conditions, −3 for use in exterior conditions)
- the letter corresponding to the intended application “S” for structural application or “NS” for general purpose
(non-structural application)
- the commercial name or botanic name of the wood species in the plywood.
3 Modification in 12.2, Other boards
Add as a new indent 3 in the first list:
- the commercial name or botanic name of the wood species in the plywood;
4 Add a New Annex B (informative), Durability of wood and wood-based products -
Definition of Use classes of biological attack- Application to plywood
Annex A
