This European Standard specifies a method of test for the determination of the protective effectiveness of a wood preservative, applied to the surface of the wood, against wood destroying basidiomycetes cultured on an agar medium.
The method is applicable to all products which are to be applied by superficial application processes. This includes:
— organic solvent-based wood preservatives; or
— organic water-dispersible formulations, as supplied or as prepared in the laboratory by dilution of concentrates; or
— water-soluble products; or
— chemicals which are being studied as active ingredients for application by superficial processes.
NOTE This method may be used in conjunction with an ageing procedure, for example EN 73.
This document specifies a method for the determination of the preventive action of a wood preservative against the Reticulitermes species of European termites1) when the preservative is applied as a surface treatment to wood.
This method is applicable to:
— water-insoluble chemicals which are being studied as active ingredients;
— organic formulations, as supplied or as prepared in the laboratory by dilution of concentrates;
— organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of concentrates, and
— water‑soluble materials, for example salts.
NOTE This method can be used in conjunction with an ageing procedure, for example EN 73 or EN 84.
1) This method can be applied not only to different species of Reticulitermes, but also to other species of the family Rhinotermitidae, where necessary adapting the temperature and humidity conditions and the assessment of attack to the specific behaviour of the species concerned.
