Over deze norm
NEN-EN 636+A1 specifies the requirements for plywood, as defined in EN 313-2, for both 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. This standard can be appropriately applied for all plywood, including overlaid and coated plywood, but it does not cover materials or processes used for overlaying or coating. Neither does it cover any materials or processes applied in relation to enhancement of biological durability. The values listed under Clause 4 relate only to product properties; they are not 'characteristic values' and are not to be used in design calculations.
