Plywood—Structural
Part 0: Specifications
SECTION 1 SCOPE AND GENERAL
1.1 SCOPE
This Standard specifies requirements for the manufacture, grading, finishing and branding
of structural plywood. Specifications for both stress and surface grades are also provided.
The Standard also specifies veneer quality, bond quality, standard lay-up construction,
dimensional tolerances, joints, moisture content and characteristic strength and stiffness
values for the nominated F-grades.
The following alternative methods for the determination of stress grades for structural
plywood, are also provided:
(a) Veneer stiffness determination.
(b) Mechanical F-grading of the finished sheet of plywood.
(c) 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.
1.2 APPLICATION
The specification for any grade of structural plywood shall consist of the requirements
given in the following Sections:
(a) General requirements ………………………………………………………… Section 1.
(b) Requirements for veneers …………………………………………………… Section 2.
(c) Manufacturing requirements …………………………………………………. Section 3.
(d) Application of stress grades and mechanical properties …………………… Section 4.
Relevant requirements are also specified in the following normative Appendices:
(i) Section properties ………………………………………………………… Appendix B.
(ii) Method for mechanically F-grading structural plywood panels ……….. Appendix C.
NOTE: Further information and guidance can be found in the following informative Appendices:
(a) For recommendations for correct storage and handling structural plywood, see Appendix A.
(b) For means for demonstrating compliance with this Standard, see Appendix D.
(c) For information to be supplied with inquiries and orders for structural plywood, see
