Standard history

This document describes a method for assessing the durability of wood-based panels or analogue wood products to attack by wood-destroying basidiomycete fungi growing in pure culture.
The test method described in this document is intended to complement EN 113-2 with focus on specific aspects of wood-based panels or analogue wood products. This document is not intended to determine the effectiveness of wood preservatives used to prevent decay, which is covered by EN 113-1.
NOTE  This method can be used in conjunction with an appropriate ageing procedure, for example EN 73 or EN 84.
The method is applicable to uncoated, rigid wood-based panel products. It is applicable to the determination of the decay resistance of wood-based panel products:
-  made from naturally durable materials;
-  made from materials treated with preservatives prior to manufacture;
-  treated with a preservative which is introduced during manufacture, for example as an additive to the adhesive;
-  specific treatments to increase durability of wood-based panels, e.g. wood modification.
