This European Standard specifies a field test method for evaluating the effectiveness of wood preservatives in a ground contact situation. Wood treated with a reference preservative is included for comparison.<\/p>\n
The protective effect of the test preservative is assessed in relation to the effect of a reference wood preservative applied by a specified treatment.<\/p>\n
