This European Standard specifies methods for the verification of compliance of one or more properties of an isolated lot of wood-based panels with the requirements of the relevant EN specification standards. Different sample sizes are given depending on wether or not the production is controlled according to EN 326-2.For panels, the production of which is controlled in accordance to EN 326-2 this European Standard can be used in case of a dispute. It is not applicable for the factory production control. For these purposes, EN 326-2 applies.In this standard, verification of compliance is based on the testing of small test pieces.
