Wood preservatives. Determination of preventive action against Reticulitermes species (European termites) (Laboratory method). | Status: Current

1 Scope This document specifies a method for the determination of the preventive action of a wood preservative against the Reticulitermes species of European termites when the preservative is applied as a surface treatment to wood.

NOTE 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.

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