Table 2 Natural durability classes of wood fungal attack using fungal culture decay testing, based on European standard EN350-1 (1994)
From: Variation in the wood properties of coast redwood trees in New Zealand
Durability class | Description | x value from fungal culture decay testing |
|---|---|---|
1 | Very durable | x ≤ 0.15 |
2 | Durable | x > 0.15 but ≤ 0.30 |
3 | Moderately durable | x > 0.30 but ≤ 0.60 |
4 | Slightly durable | x > 0.60 but ≤ 0.90 |
5 | Not durable | x > 0.90 |
