Abstract
:1. Introduction
2. Materials and Methods
2.1. Preparation of Particleboards
2.2. Subterranean Termite Test
Item | Description |
---|---|
General | No-choice test |
Test termite species | Coptotermes curvignathus Holmgren |
Number of termites used per test unit | 200 workers |
Wood specimens | Species: Not specified for control wood Size: 2.5 cm (L) × 2.5 cm (T) × 0.5 cm (R) (dressed sawn) |
Pre- and post-conditioning of wood specimens | Oven-drying at 102 ± 3 °C until no weight change detected |
Weathering procedure | Not specified |
Test container | Round jam pot (450–500 mL capacity) with a wide-mouth and a bottom area of 25–30 cm2 |
Test assembly | An individual wood specimen buried in 200 g sand at 7% MC below water holding capacity of the sand (or moist sand) in the jam pot so that one of the largest areas of the sample (the widest part) allowed to contact inside vertical wall of the pot |
