In the event that there is no information on the durability of a given  species, the final 
decision regarding its use for any particular purpose should be made by a specialist, taking 
into account the presence of biodegradation agents, the risks , the environmental 
conditions and other conditions that may arise. Timber used as construction material 
should be protected and maintained with products that prevent the action of 
biodegradation agents, based on the durability level established in the not ified standard. 
Accordingly, timber classed as non -durable should be preserved, and timber of a medium 
durability should be treated with protective products depending on the circumstances  and 
the specific biodegradation agent. The background information pr ovided in Annex A
