DIN EN 636:2012-12

This European Standard specifies the requirements for plywood for general purpose use (non-structural application) and structural application in dry, humid or exterior conditions. It also gives a classification system based on the bending properties. All plywood, independent of composition factors (for example, species, number of plies, thickness of plies) can be classified under this system. The classification system may be used as an alternative to the full-scale testing as required by EN 789, for the derivation of characteristic values for plywood. Compared to EN 636:2003, the classification system for bending strength and bending modulus completed with classes F 35 and E 35, the limit values in Table 2 have been changed. The letter indicating the intended application changed from "G" to "NS". Furthermore, the marking of formaldehyde release has been aligned with EN 13986. The responsible committee is NA 042-02-15 AA "Holzwerkstoffe - Spiegelausschuss zu CEN/TC 112 und ISO/TC 89" ("Wood-based panels - Mirror Committee of CEN/TC 112 and ISO/TC 89").
