EVS-ENV 1099:1999

This European Pre-standard gives guidances on the selection of plywood for use in the different hazard classes of biological attack as defined in EN 335-1. The guidance given takes into account the natural durability classification for solid timber (see EN 350-2) together with other factors specific for plywood. It does not consider durability against chemico-physical factors, such as weathering, nor does it consider the biological durability of the adhesive.
