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.

The description of the newly included preservatives is added into relevant clauses and Appendix B.
