Describes a method for the determination of the toxic values of a wood preservative against the Reticulitermes species of European termites.

This European Standard specifies a method for the determination of the toxic values of a wood preservative against the Reticulitermes species of European termites¹⁾.

This method is applicable to:

• water-insoluble chemicals which are being studied as active insecticides;

• 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.
