European Standard EN 350 gives guidance on methods for determining and classifying the durability of wood/bamboo against biological wood-destroying fungi. The natural durability of wood/bamboo can be classified ranging from 1 (very durable) to 5 (not durable). As given in EN 350 standard there are two laboratory methods for determining the 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 reach the highest durability class (class 1, very durable), which means the product can be used in applications in direct or without ground contact. MOSO® Bamboo N-Finity products are (at present) only tested following CEN/TS 15083-1 and reach the highest durability class (class 1, very durable), which means the product can be used in applications without ground contact.
