This document specifies a method for determining the efficacy of wood preservatives applied to wood by penetration treatment against wood destroying basidiomycetes cultured on a malt extract agar medium.

The method is applicable to formulated products or to their active ingredients.

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

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

Annex B (informative) contains some methods of sterilization.

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

Annex D (informative) contains information on test fungi.

Annex E (informative) contains a recommended but non-comprehensive list of optional fungi.

This document specifies a method of test for determining the natural durability of a timber against wood-destroying basidiomycetes cultured on a malt extract agar medium. The method is applicable to all timber species.

Furthermore this method can be used to test modified or treated wood. The test method described in this part 2 of EN 113 can be applied to specific wood species, commercial supplies of sawn timber, wood-based materials, wood treated with preservatives and modified wood including heat-treated wood. However, this standard is not intended to determine the effectiveness of wood preservatives used to prevent decay.

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

NOTE 2       This method can be used in conjunction with an ageing procedure, for example EN 73 or EN 84.

Annex A (informative) contains a guidance on sampling.

Annex B (informative) contains some methods of sterilization.

Annex C (informative) contains information on the test 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.

This document specifies a method for the determination of the eradicant action of a surface application of a fast and a slow acting wood preservative product or a deferred acting wood preservative product on timber infested with larvae of Hylotrupes bajulus (Linnaeus).

This method is applicable to:

—    organic formulations, as supplied or as prepared in the laboratory by dilution of concentrates; or

—    organic water-dispersible formulations, as supplied or as prepared in the laboratory by dilution of concentrates; or

—    water-soluble products, for example, salts.

NOTE          An ageing procedure cannot be combined with this method.
