Describes procedures for the sampling of expanding admixtures or premixed materials containing an expanding admixture.

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.
