European Standard EN 350 guides the methods used for determining and classifying the durability of wood and bamboo regarding biological, wood-destroying fungi. The natural durability of wood and bamboo classifications range from 1 (very durable) to 5 (not durable). Using the EN 350 standard, there are two laboratory methods for determining durability: CEN/TS 15083-2 for the application of products in direct ground contact and CEN/TS 15083-1 for the application of products without ground contact.
In both tests MOSO® Bamboo X-treme® products achieved the highest durability class attainable (Class 1, very durable), concluding that the products can be applied with or without ground contact. MOSO® Bamboo N-Finity products are currently tested following CEN/TS 15083-1, also meeting the highest durability class (Class 1, very durable), concluding that the product can be used in applications without ground contact.
