PHYSICAL AND MECHANICAL PROPERTIES

These properties can vary significantly depending on the origin and growing conditions of the wood.

• Density *: 0.74
• Monnin hardness *: 3.7
• Coef. Volume shrinkage: 0.48%
• Stability in service: moderately stable to poorly stable
• Total radial shrinkage: 4.6%
• Fiber saturation point: 34%
• Total tangential shrinkage: 10.6%

(*: 12% humidity)

NATURAL DURABILITY AND IMPREGNABILITY OF WOOD

• Mushrooms: cl 4 – weakly durable
• Insects of dry wood: susceptible; sapwood little or not distinct (risk in all the wood
• Termites: class S – susceptible
• Impregnability: 3-4 little or no impregnation
• Biological risk class: 2 – out of contact with the ground, sheltered (risk of humidification)

Sensitive to bluing.

SAWING AND MACHINING

• Blunting effect: normal
• Teeth for sawing: ordinary or alloy steel
• Machining tools: ordinary

Tearing off or planing. Difficult finish. Filling is necessary.

ASSEMBLY

• Nailing – Screwing: good hold
• Gluing: correct

USES

• furniture
• interior carpentry
• paneling
• parquet

Main known uses to be validated by implementation in compliance with the rules of the art. Important note: some uses are mentioned for information.

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 timber, classified, with a minimum average density of 0.35 and a minimum thickness of 22 mm.
