21/30433969 DC

This standard 21/30433969 DC BS EN 113-3. Durability of wood and wood-based products. Test method against wood destroying basidiomycetes is classified in these ICS categories:

• 79.060.01 Wood-based panels in general

This document describes a method for assessing the durability of wood-based panels or analogous 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 .

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:

1. made from naturally durable materials;

2. made from materials treated with preservatives prior to manufacture;

3. treated with a preservative which is introduced during manufacture, for example as an additive to the adhesive;

4. specific treatments to increase durability of wood-based panels, e.g. wood modification
