| 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 M – moderately durable |
| Treatability (according to E.N. standards): |
class 4 – not permeable |
| Use class ensured by natural durability: |
class 3 – not in ground contact, outside |
| Species covering the use class 5: |
No |
| Note: |
This species is listed in the European standard NF EN 350-2. Durability is linked to the presence of water soluble tanins. It decreases with tanins washing in case of harsh exposition.
According to the European standard NF EN 335, performance length might be modified by the intensity of end-use exposition. |
