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) |
