Durability Notes: This species is listed in the NF EN 350 standard. Information regarding the natural durability and preservation treatment requirements correspond to phenomena observed in most species of the genus. Species of certain origins, in particular Dialium pachyphyllum and Dialium aubrevillei, show less durability (durability class 3 or 4). According to the European standard NF EN 335 of May 2013, performance length might be modified by conditions in which it is used.
