Description

BS EN 113-3, 2023 Edition, February 28, 2023 - Durability of wood and wood-based products - Test method against wood destroying basidiomycetes Part 3: Assessment of durability of wood-based panels

Scope

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. 

This document describes a laboratory test method in which small samples of the wood-based panel product under test are exposed to attack by a range of wood-destroying basidiomycete fungi in pure culture. The thickness of the test specimens varies, since it is dictated by the thickness of the wood-based panel product under test. The effect of constituents giving temporary protection is avoided by testing after pre-conditioning of the cut specimens in a freely ventilated environment. The test method also includes a minimum moisture uptake requirement.
