Provides a specification for preservative treatment of reconstituted wood-based products for protection against decay or insect attack. It covers preservative treatment of particleboard, oriented strand board (OSB), and combinations of these materials. It specifies preservative penetration patterns and the preservative retention requirements suitable for each of hazard classes H1 to H3.

This standard sets out a specification for preservative treatment of reconstituted wood-based products including particleboard and oriented strand board or combinations of these materials. It specifies the preservative penetration pattern and the preservative retention requirements suitable for each hazard class (see Table 1).Where the reconstituted wood-based products are engineered with other components such as solid wood or LVL in I-beams, or face-veneers on boards, the preservative treatment of these individual components shall be in accordance with the relevant Parts of the AS 1604 series.This Standard does not cover grade or seasoning condition.
