This Standard specifies requirements for preservative-treated sawn and round timber for protection against decay, insect or marine borer attack. It incorporates borate treatment for hazard class 2, TBTN/permethrin treatment for hazard class 3, and ammoniacal copper quaternary (ACQ) for hazard classes 1 and 3 for hardwood and hazard classes 2 to 5 for softwood. This revision omits the equivalent retention levels of individual pieces expressed on a mass/volume basis. The description of the newly included preservatives is added into relevant clauses and Appendix B. Appendix C provides information on the allocation and registration of treatment plant numbers and preservative code numbers.

This Standard specifies requirements for preservative-treated sawn and round timber that is required to be protected against decay, insect or marine borer attack for all exposure conditions throughout Australia, with limitations described in Clause 3. This Standard does not cover grade or seasoning condition.
