This document specifies a test method to measure the formaldehyde concentrations in air from wood products under defined test conditions of temperature and relative humidity. Results obtained from this small-scale chamber test method are often used for quality assurance and can be comparable to, or can provide useful correlations to, results obtained from testing larger product samples in larger chamber test methods for wood products, such as the 1 m3 chamber method specified in ISO 12460-1. NOTE 1 This document is based on the general principles and methods of ASTM D 6007. NOTE 2 ISO 12460-1 for the 1 m3 chamber is the reference method for the determination of formaldehyde release. For factory production control the derived test methods according to this document, ISO 12460-3, ISO 12460-4 and ISO 12460-5 are used.

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).

This European Standard specifes principle material requirements for timber and wood-based products in internal windows, doors and doorframes (with or without fixed parts), including appearance, biological durability and other physical characteristics.
This European Standard applies to factory assembled internal windows, door leaves and doorframes uncoated or intended to be coated.
If doors are covered by other decorative veneers or films the respective veneer or film Product Standard shall apply.
EXAMPLE   Timber veneers may be graded to EN 635: Parts 1, 2, 3 and 5, and ENV 635 4.

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).

This standard specifies test methods for determining some mechanical properties of commercial wood-based panel products for use in load-bearing timber structures. These properties are intended for the calculation of characteristic values for use in obtaining material design values. For each type and grade of panel product, as defined for example in an EN wood based panel standard, it is necessary to determine characteristic values of mechanical properties to enable it to be used for structural purposes.

This European Standard specifies a chamber method with three options of test chambers for the determination of the formaldehyde emission from wood-based panels in terms of the steady-state concentration in a climate chamber under defined conditions, which relate to typical conditions in real-life. This chamber method can also be applied to the estimation of formaldehyde concentrations under various conditions in practice, by the use of mathematical models.
