This document defines wood-based panels for use in construction and specifies the relevant characteristics and the appropriate test methods to determine these characteristics for wood-based panels, unfaced, overlaid, veneered or coated:
-   for internal use as structural components in dry conditions ) ;
-   for internal (or protected external) use as structural components in humid conditions ) ;
-   for external use as structural components ) ;
-   for internal use as non-structural components in dry conditions1);
-   for internal (or protected external) uses as non structural components in humid conditions2);
-   for external use as non-structural components3);
-   for use as structural floor decking on joists in dry1) or humid2) or external3) conditions;
-   for use as structural roof decking on joists in dry1) or humid2) or external3) conditions;
-   for use as structural wall sheathing on studs in dry1) or humid2) or external3) conditions.
   It provides for the evaluation of conformity and the requirements for marking these products.
This document covers wood-based panels in the form of solid wood panels, LVL ) , plywood, OSB, particleboards (chipboards) either resin- or cement-bonded, wet process fibreboards (hardboards, medium boards, softboards) and dry process fibreboards (MDF) for use in construction. They may contain chemical agents to improve their reaction to fire and their resistance to biological attack, e.g. by fungi and insects.
This document is not intended to be applicable to wood-based panels for use in non-constructional applications.

Wood-based panels - Sampling, cutting and inspection - Part 2: Initial type testing and factory production control
SIST EN 326-2:2011+A1:2014

This European Standard specifies methods for internal initial type testing (ITT) and internal factory production control (FPC) as well as external control of wood-based panels for their compliance with EN 13986 and other relevant product specifications. However, it may also apply, at the option of the manufacturer, to wood-based panels applied for non-construction purposes.
This European Standard is not applicable for the assessment of compliance with specifications of panels comprised in consignments. In such cases, EN 326-3 applies.
For internal factory production control, if required, methods for the assessment of conformity of batches and of production over longer periods are given.
For external control, if required, methods for the initial inspection of a factory and initial type testing of a product, and for the surveillance of the factory production control, are given.
In the factory production control small test pieces are used. The statistics of evaluation is based on normal distribution.

EN 12871:2013(Main)
Wood-based panels - Determination of performance characteristics for load bearing panels for use in floors, roofs and walls
SIST EN 12871:2013

This European Standard specifies:
-   concentrated load test and assessment methods for floor and roof decking;
-   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.
Annex C (informative) provides examples for a decking application in a floor and a roof.

Wood-based panels - Determination of duration of load and creep factors
SIST EN 1156:2013

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.
