What is BS EN 252 - Protective effectiveness of a wood preservative in ground contact about?
BS EN 252 is a European standard that discusses evaluating the effectiveness of wood preservatives.
BS EN 252 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.
The protective effect of the test preservative is assessed in relation to the effect of a reference wood preservative applied by a specified treatment.
Who is BS EN 252 - Protective effectiveness of a wood preservative in ground contact for?
BS EN 252 on protective effectiveness of a wood preservative in ground contact is useful for:
