PHYSICAL AND MECHANICAL PROPERTIES
These properties can vary significantly depending on the origin and growing conditions of the wood.
- Density *: 0.66
- Monnin hardness *: 3.8
- Coef. Volume shrinkage: 0.44%
- Stability in service: not very stable
- Total radial shrinkage: 4.6%
- Fiber saturation point: 28%
- Total tangential shrinkage: 7.4%
(*: 12% humidity)
NATURAL DURABILITY AND IMPREGNABILITY OF WOOD
- Mushrooms: cl 1 – very durable
- Dry wood insects: durable; distinct sapwood (risk limited to sapwood)
- Termites: class D – durable
- Impregnability: 4 – not impregnable
- Biological risk class: 3 – out of contact with the ground, not sheltered
Although BETE is listed in class 1 for natural durability with respect to fungi (very durable) in the NF EN 350-2 standard, it should be noted that it is sensitive to attacks by the fibrous rot fungus “Coriolus versicolor “; hence its classification in 2 (sustainable).

REACTION TO FIRE
- French conventional classification: thickness> 14 mm: M.3 (moderately flammable) thickness <14 mm: M.4 (easily flammable)
- classification according to euroclasses: D s2 d0 This default classification concerns solid woods meeting the requirements of standard NF EN 14081-1 appendix C (May 2006), used in vertical walls. Namely structural wood, classified, with a minimum average density of 0.35 and a minimum thickness of 22 mm.
