NATURAL DURABILITY AND TREATABILITY
| Funghi (according to E.N. standards): |
class 2 - 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 3 - poorly permeable |
| Use class ensured by natural durability: |
class 4 - in ground or fresh water contact |
| Species covering the use class 5: |
No |
| Note: |
This species is listed in the European standard NF EN 350-2. 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: | Requires power. Some difficulties due to interlocked grain. Sometimes white efflorescence on sawnwoods; a wash with warm water can remove it. |
