Provides producers and users of large cross-section sawn hardwood engineering timbers with requirements for the visual grading and selection of species for such timbers intended for use in structures.

This Standard sets out the minimum requirements for visually graded large cross-section sawn hardwood engineering timbers greater than 0.016 m2 in cross-section. These minimum requirements apply at the time of grading.For structures using large section timber members, the sizes of members are calculated from the known or assumed loads on the members and dimensional requirements specified in the order.NOTES:1 A cross-section 200 mm ( 80 mm has an area of 0.016 m2.2 Purchasing guidelines are given in Appendix A.3 Stress grades for design (using AS 1720.1) of timbers graded to this Standard are given in Appendix B.
