This European Standard describes a method for assessing the resistance of wood-based panel products to attack by wood-destroying basidiomycete fungi growing in pure culture. 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; — treated with preservative after manufacture. NOTE 1 This method can be used in conjunction with an appropriate ageing procedure, for example EN 73 or EN 84. NOTE 2 Wood-based panel products that have received a preservative treatment after manufacture can be susceptible to attack through the cut edges of the test specimens and the decay resistance indicated can be less than that of complete panels used in service. 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.
