Durability of wood and wood-based products. Efficacy of preventive wood preservatives as determined by biological tests - Specification according to use class Ingestion-build-225643 0 ng/l to 10 0001 Scope This part of EN 599 specifies for each of the five use classes defined in EN 3351, the biological tests required for evaluating the efficacy of wood preservatives for the preventive treatment of solid timber, together with the minimum ageing tests required for the respective use class. It provides the method for calculating the critical value of a preservative. The critical value is the value that shall be used to calculate the recommended
