ANNEX IVWHITE OAK LOG IDENTIFICATION

Officials of the official plant protection organisation concerned shall have identified each log as belonging to the white oak group either by visual means, as far as possible, or by carrying out white oak log identification colour tests as specified in 2. This identification colour test shall be performed on at least 10 % of the logs per consignment.

The white oak log identification colour test shall be carried out by means of spraying or painting 10 % sodium nitrite solution to an area of clean superficially dried heartwood at least five centimetres in diameter. Evaluation of the test shall be done within 20 to 60 minutes of application. At temperatures below 2,5 °C, 20 % ethylene glycol can be added to the solution as an antifreeze agent. Samples of logs in which the natural colour initially turns reddish brown becoming black to grey blue in later stages are considered as belonging to the white oak group.
