Specifies requirements for the manufacture, grading and finishing of plywood intended for marine use. It specifies face veneer quality A, which matches with veneer quality A in AS/NZS 2269, and a minimum stress grade of F14. Tests are prescribed by reference to AS/NZS 2098.

This Standard specifies requirements for the manufacture, grading and finishing of plywood intended for marine use. It describes the basic marine plywood product. Particular applications may require additional processing, preservative treatment or surface finishing. The species from which marine plywood is manufactured have limited natural resistance to decay and it should be noted that although bonded with a durable Type A bond in accordance with AS 2754.1 -1985, this bond durability does not impart additional durability to the wood.This Standard also specifies species of timber, veneer qualities, bond quality, joints, veneer construction, moisture content, dimensions and tolerances, finishing and branding. A series of performance requirements relating to species, and a procedure for evaluating and admitting new species are included.One bond type, Type A bond, is prescribed.The specification for any grade of marine plywood shall consist of the general requirements given in this section together with the relevant requirements for veneer given in Section 2 and the manufacturing requirements given in Section 3.
