This Standard specifies requirements for the manufacture and grading of structural plywood. The Standard specifies veneer quality, bond quality, dimensional tolerances, joints, moisture content, visual grading rules and basic working stresses for the nominated stress grades as well as alternative methods for the determination of stress grades. Five surface grades, A, S, B, C and D, and one bond quality, Type bond, are prescribed.

This Standard specifies requirements for the manufacture and grading of structural plywood. Specifications for both stress and surface grades are also provided. The Standard also specifies veneer qualities, bond quality, standard lay-up construction, dimensional tolerances, joints, moisture content and basic working stresses for the nominated stress grades. The following alternative methods for the determination of stress grades for structural plywood, are also provided-(a) species identification;(b) density determination;(c) veneer stiffness determination;(d) mechanical stress grading of the finished sheet of plywood; or(e) in-grade testing of finished plywood panels.Five surface grades, based on the veneer quality of the face and back veneers, A, S, B, C and D and one bond quality, Type A bond, are prescribed.
