Test method for determining protective efficacy against lignivorous basidiomycete fungi - Determination of efficacy threshold/Determination of natural durability of wood and improved durability
03.022026
Standard NF EN 113-1 determines the effectiveness of wood treatment products against cubic and fibrous decay fungi (basidiomycetes). Standard NF EN 113-1 describes a laboratory test method that determines the effectiveness threshold of a product against wood-decaying fungi.
Standard EN 113-2 applies to specific species of raw wood and modified wood species (thermally and chemically). It determines the durability class of wood against basidiomycete fungi.
In EN113-1, samples of Scots pine and beech are treated with different concentrations of the product by impregnation. They are then subjected to accelerated ageing and exposed to wood-decaying fungi cultures over a period of several months. The effective concentration of the treatment product is assessed based on the loss of mass caused by the fungi, using the criteria set out in EN599-1.
In EN113-2, samples of wood (natural or modified) to be tested are exposed to cultures of wood-destroying fungi over a period of several months. The durability class of the wood is assessed based on the loss of mass caused by the fungi, in accordance with the criteria of EN350.
