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?

Why should you use BS EN 252 - Protective effectiveness of a wood preservative in ground contact?

The protective effectiveness of a wood preservative test method helps to control wood degradation problems due to fungal rot or decay, sap stain, molds, or wood-destroying insects.

BS EN 252 describes the method of testing that gives a basis for the assessment of the preventive action of a wood preservative, when applied as a surface treatment, against microbial attack.

BS EN 252 specifies a field test method for evaluating the effectiveness of wood preservatives to protect the wood from cracks, stains, decay, insect damage, and other defects that help you manufacture the wood product with quality.

BS EN 252 exemplifies the required test method for evaluating the effectiveness of wood preservatives that help you achieve precision in terms of product functionality.
