These conditions correspond with service class 2 according to ENV 199511. Boards of this type are suitable for use in biological hazard class 1 and 2 of EN 3353 NOTE This plywood is appropriate for protected external applications (. behind cladding or under roof coverings), but is also capable of resisting weather exposure for short periods (. when exposed during the construction). It is also suitable for interior situations where the service moisture condition is raised above humidity of dry conditions. plywood for use in exterior conditions (EN 6363) plywood to be used in climatic conditions leading to higher moisture contents than in service class 2. These condi tions correspond with service class 3 according to ENV 199511. Boards of this type are suitable for use in biological hazard class 1, 2 and 3 of EN 3353 NOTE It is capable of withstanding exposure to weathering conditions and liquid water, or water vapour in a damp but ven tilated location, under consideration of . 4 Classification system For the purpose of this standard, all types of plywood can be classified under a system independent of the po sition factors (species, number of plies, thickness of the plies etc.) and based on the bending properties. This classification system may be used to provide characteristic values for structural uses without testing semisize test pieces referring to prEN 123692. The values given in Tables 1 and 2 correspond to 5 percentile values based on the mean values, determined according
