This European Prestandard (ENV) was approved by CEN on 5 April 2002 as a prospective standard for provisional application.
The period of validity of this ENV is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the ENV can be converted into a European Standard.
CEN members are required to announce the existence of this ENV in the same way as for an EN and to make the ENV available promptly
at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the ENV) until the final
decision about the possible conversion of the ENV into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,
Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

EN 636:2012+A1:2015(Main)
Plywood - Specifications
SIST EN 636:2013+A1:2015

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.

EN 14272:2011(Main)
Plywood - Calculation method for some mechanical properties
SIST EN 14272:2012

This European Standard specifies, for plywood panels of any composition, symmetrical or not, a calculation method to derive some mechanical properties (strength and stiffness in bending, tension, compression, panel and planar shear) as well as density from the wood compounding the layers.
NOTE   Usually, the lay-up of the panels is symmetrical but, very often, the surface appearance of the face and the surface appearance of the back face differ, hence a difference between the mechanical properties of the respective veneers. Therefore, in this case, the composition is not mechanically symmetrical and a symmetry independent calculation method is needed.
Provided that structural characteristic values are taken for the layers, the resulting values for the panels can be used as characteristic values as required by EN 1995-1-1.
Conversely, Annex A defines the procedures to derive the veneer properties, in bending, tension and compression, either from testing panels according to EN 789 and EN 1058 or from timber testing according to EN 408 or from imposed values defined in EN 338.
Annex B provides practical spreadsheets, which are applications of the equations in the main part of this standard.
Annex C provide an example for the calculation of bending strength, in accordance with Annex B.

EN 12369-2:2011(Main)
Wood-based panels - Characteristic values for structural design - Part 2: Plywood
SIST EN 12369-2:2011

This European Standard provides information on the characteristic values for use in designing structures incorporating wood-based panels. The characteristic values given in this standard are to be used in accordance with  EN 1995-1-1.
When utilizing the classification system for derivation of plywood characteristic values, this part of this standard can only be applied with reference to EN 636.
This part of this standard includes the characteristic values of the mechanical properties for plywood complying with EN 636 in bending, tension, compression, panel shear and planar shear. EN 636 classifies bending properties into two sets of classes, one for stiffness and another for strength. Stiffness and strength in tension and compression are related to the same properties in bending.
For shear properties, fixed values determined by correlation to density are provided.
Where optimised values are needed, the characteristic values are determined directly by testing in accordance with EN 789 and EN 1058 or by combination of testing according to the latter two standards and calculation according to prEN 14272.
This part of this standard applies to panels complying with the three following conditions:
-   5 layers or more and 6 mm overall thickness and more;
-    the ratio of the cumulative thickness of veneers in alternate directions does not exceed 2,5;
-    wood species with a mean density greater than 350 kg/m3 and not exceeding 750 kg/m3.

Plywood - Biological durability - Guidance for the assessment of plywood for use in different use classes
SIST-TS CEN/TS 1099:2008

This document gives guidance on the selection of plywood for use in the different use classes as defined in EN 335 1.
The guidance given takes into account the natural durability classification for solid timber (see EN 350 2) together with other factors specific for plywood.
It does not consider durability against chemico-physical factors, such as weathering, nor does it consider the biological durability of the adhesive.
Guidance on precautionary measures for use is also given.
