(*: at 12% moisture content, with 1 MPa = 1 N/mm²) Musical quality factor: 148,4 measured at 2658 Hz |
NATURAL DURABILITY AND TREATABILITY
Funghi (according to E.N. standards): |
class 1 - very durable |
Dry wood borers: |
durable - sapwood demarcated (risk limited to sapwood) |
Termites (according to E.N. standards): |
class D - durable |
Treatability (according to E.N. standards): |
class 2 - moderately permeable |
Use class ensured by natural durability: |
class 4 - in ground or fresh water contact |
Species covering the use class 5: |
Yes |
Note: |
This species is listed in the European standard NF EN 350-2. It naturally covers the use class 5 (end-uses in marine environment or in brackish water) only for end-uses under temperate and cold environment. According to the European Standard NF EN 335, performance length might be modified by the intensity of end-use exposition. |
SAWING, MACHINING AND ASSEMBLING
Blunting effect: |
fairly high |
Sawteeth recommended: |
stellite-tipped |
Cutting tools: |
tungsten carbide |
Peeling: |
not recommended or without interest |
Slicing: |
nood |
Note: | Sometimes, irritant sawdust. Requires power. Sometimes, difficulties, difficulties due to interlocked grain. |
Nailing / screwing: |
good but pre-boring necessary |
Gluing: |
correct |
Note: |
Pre-boring necessary: risks of splits especially with thin boards. Gluing requires care (dense wood) |
