-   soft body impact assessment methods and classification system for floors, roofs and walls.
This European Standard does not include racking testing or uniformly distributed loads as these are covered by testing according to EN 594 or calculation according to EN 1995-1-1 respectively.
This European Standard specifies the procedure for determining the performance characteristics through type testing, of load-bearing wood-based panels fitted on:
a)   structural joists for decking:
1)   in flooring applications in load categories A, B, C and D;
2)   in roof applications in load categories H and I;
for which type testing involves:
i)   punching shear under concentrated loading;
ii)   vertical soft body impact;
b)   studs for walling application for which type testing involves:
1)   pendular soft body impact.
Annex A (normative) lists modifications to EN 1195, particularly the contact area of the loading head that may be used for concentrated loading.
Annex B (informative) provides proposals for national performance requirements.

This European Standard specifies a method of determining in a constant climate both a duration of load factor and a creep factor for wood-based panels stressed in flatwise bending with and without a shear component. Details of an alternative but provisional method employing medium sized test pieces are given in Annex A; this method can also be used for test pieces loaded under varying climates.
NOTE   The duration of load factor is necessary to modify the characteristic strength values obtained in short-term structural tests in order to derive long-term values. The creep factor obtained in the test is used to predict a long-term deflection from the initial elastic deflection.

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.

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.

This Technical Specification specifies small-scale test methods for estimating the following mechanical properties of wood-based panels:
-   indicative planar shear strength (sometimes referred to as block shear);
-   indicative panel shear strength;
-   indicative strength and modulus of elasticity in tension in the plane of the panel;
-   indicative strength in compression in the plane of the panel.
Reference should be made to EN 310 for bending properties. For plywood, EN 314 1 may also be used as an indicator of planar shear strength.
These test methods are intended for indicative purposes only and should not be used as a means of determining structural design values. They may not be suitable for all panel types. They may be used as a means of supporting quality control procedures for structural panels, if correlations with EN 789 test results can be established (CEN Technical Report in preparation).
