Wood preservatives. Determination of the relative protective effectiveness of a wood preservative for use under a coating and exposed out-of-ground contact. Field test: L-joint method Ingestion-build-83346 operating from a1 Scope This European Standard specifies a method for determining the relative protective effectiveness against fungal decay of a wood preservative applied to wood in combination with a subsequent surface coating, exposed to the weather and out of contact with the ground. The effectiveness is evaluated relative to a reference wood preservative. The method is applicable to the testing of commercial or experimental preservatives applied to non durable
