AS/NZS 6669 is an Australian/New Zealand Standard that typically covers the specifications and requirements for a specific type of plywood known as Formply.
Formply, or formwork plywood, is designed for use in concrete formwork applications. It is used as a facing material for formwork to create the mold into which concrete is poured.

Formply, or formwork plywood, is designed for use in concrete formwork applications. It is used as a facing material for formwork to create the mold into which concrete is poured.
Key considerations in the AS/NZS 6669 standard for Formply may include:
Veneer Quality: The standard may specify the quality of veneers used in the plywood, including the characteristics of individual veneer sheets and their assembly.
Adhesive Type: The type of adhesive used in the plywood construction may be addressed in the standard. Adhesives play a crucial role in ensuring the bond strength and durability of the plywood.
Bonding Quality: The standard may include requirements for the bonding quality between layers of veneer. This is important to ensure the structural integrity of the plywood.
Thickness Tolerances: Standards often specify the allowable thickness tolerances for different plywood grades to ensure consistency in the manufactured product.
Moisture Resistance: Given the application in concrete formwork, standards may address the moisture resistance properties of Formply to prevent swelling or delamination during use.
Surface Finish: The standard may specify the surface finish and quality, considering factors such as smoothness and appearance.
Durability and Structural Properties: AS/NZS 6669 may include requirements related to the durability and structural properties of Formply, ensuring that it meets the necessary performance standards for formwork applications.
