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 .

NOTE 1

Determining the efficacy of wood preservatives used to prevent decay is the scope of EN 113‑1 .

NOTE 2

This method may be used in conjunction with an ageing procedure, for example EN 73 or EN 84 .

NOTE 3

Complementary to EN 113‑2 this part focusses on specific test procedure for wood-based panels or analogous wood products.

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

NOTE 4

This method can be used in conjunction with an appropriate ageing procedure, for example EN 73 or EN 84 .

Annex A (informative) contains a guidance on sampling.

Annex B (normative) contains some methods of sterilization.

Annex C (informative) contains information on the culture vessels.

Annex D (informative) contains an example of a test report.

Annex E (informative) contains information on the test fungi.

Annex F (informative) contains the assessment of the results.

Annex G (informative) contains extra info on moisture dynamics, coatings, composites and impact of dimensions
