NATURAL DURABILITY AND TREATABILITY
Funghi (according to E.N. standards): |
class 3 - moderately durable |
Dry wood borers: |
durable - sapwood demarcated (risk limited to sapwood) |
Termites (according to E.N. standards): |
class M - moderately durable |
Treatability (according to E.N. standards): |
class 3-4 - poorly or not permeable |
Use class ensured by natural durability: |
class 2 - inside or under cover (dampness possible) |
Species covering the use class 5: |
No |
Note: |
This species is listed in the European standard NF EN 350-2. Variable natural durability towards fungi. |
SAWING, MACHINING AND ASSEMBLING
Blunting effect: |
fairly high |
Sawteeth recommended: |
stellite-tipped |
Cutting tools: |
tungsten carbide |
Peeling: |
good |
Slicing: |
nood |
Note: | Requires power. Blunting effect due to hardness. Tends to clog sawteeth when green. Sometimes difficulties due to interlocked grain. |
Nailing / screwing: |
good |
