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.#,,#
