Flexure tests on flat sandwich constructions may be conducted to determine the sandwich flexural stiffness, the core shear strength and shear modulus, or the facings compressive and tensile strengths. Tests to evaluate core shear strength may also be used to evaluate core-to-facing bonds. This practice provides a standard method of determining sandwich flexural and shear stiffness and core shear modulus using calculations involving measured deflections of sandwich flexure specimens. Tests can be conducted on short specimens and on long specimens (or on one specimen loaded in two ways), and the flexural stiffness, shear rigidity and core shear modulus can be determined by simultaneous solution of the complete deflection equations for each span or each loading. If the facing modulus values are known, a short span beam can be tested and the calculated bending deflection subtracted from the beamrsquo;total deflection. This gives the shear deflection from which the transverse shear modulus can be determined. Note 18212;Core shear strength and shear modulus are best determined in accordance with Test Method C 273 provided bare core material is available. Note 28212;For cores with high shear modulus, the shear deflection will be quite small and ordinary errors in deflection measurements will cause considerable variations in the calculated shear modulus. Note 38212;To insure that simple sandwich beam theory is valid, a good rule of thumb for a four-point bending test is the span length divided by the sandwich thickness should be greater than 20 (L1/d > 20) with the ratio of facing thickness to core thickness less than 0.1 (t/c < 0.1).1.1 This practice covers determination of the flexural and transverse shear stiffness properties of flat sandwich constructions subjected to flexure in such a manner that the applied moments produce curvature of the sandwich facing planes. Permissible core material forms include those with continuous bonding surfaces (such as balsa wood and foams) as well as those with discontinuous bonding surfaces (such as honeycomb). The calculation methods in this practice are limited to sandwich beams exhibiting linear force-deflection response. This practice uses test results obtained from Test Methods C 393/C 393M and/or D 7249/D 7249M.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

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 Prestandard 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 average 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.

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 load-bearing panel product, as defined in the Harmonised Standard for wood-based panels (EN 13986), it is necessary to determine characteristic values of mechanical properties to enable it to be used for structural purposes. This standard details the testing required to establish characteristic values. The tests need only be carried out once for each product, unless there is a reason to suspect a significant change has occurred in the properties of the product.#,,#

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. This standard can also be used for the testing of formaldehyde emissions of products other than wood-based panels.
