Provides minimum performance requirements and specifications for the manufacture and application of plywood for use in the specific application of concrete formwork in Australia.

This Standard specifies requirements for the manufacture, grading, finishing and branding of plywood used specifically in formwork, with a maximum length of 3100 mm and width of 1500 mm, intended to meet off-form surface finish requirements Classes 2, 3, 4 and 5 as specified in AS 3610. This Standard does not include specifications for formwork plywood intended to meet off-form surface finish Class 1.Specifications for stress and surface grades, overlays, veneer qualities, bond quality, standard lay-up construction, dimensional tolerances, joints, moisture content and characteristic strength and stiffness values for the nominated F-grades are provided.The following alternative methods for the determination of stress grades for formwork plywood are specified:(a) Veneer stiffness determination.(b) Mechanical F-grading of the finished sheet of formwork plywood.(c) In-grade testing of finished formwork plywood panels.Three outer veneer grades, based on the veneer quality of the face and back veneers, F, C and D are prescribed and four surface quality grades Class 2, Class 3, Class 4 and Class 5 are described.Three bond types A, B and C are specified.Formwork plywood is usually a multiple-use product. The physical and structural characteristics of formwork plywood products, as branded and specified in this Standard, are appropriate for the products as supplied. Inspection of the product is required between uses to ensure ongoing required performance across all characteristics. Structural adjustment factors for multiple uses are specified in AS 3610.
