[Superseded]Plywood — Structural
Specifies requirements for the manufacture, grading, finishing and branding of structural plywood. It provides specifications for both stress and surface grades and specifies veneer qualities, bond quality, standard lay-up construction, dimensional tolerances, joints, moisture content and characteristic strength and stiffness values for the nominated stress grades. 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.
