Use Class Covered by Natural Durability: Class 4 – in ground or fresh water contact Notes. This species is listed in the NF EN 350 standard. This species naturally covers the use class 5 (wood permanently MUHUHU
Durability Notes: This species is listed in the NF EN 350 standard. This species naturally covers the use class 5 (wood permanently MUHUHU Cross sections of Brachylaena huillensis or regularly submerged in salt water, sea water or brackish water) due to its pronounced hardness. According to the European standard NF EN 335 of May 2013, performance length might be modified by conditions in which it is used.
