Specifies requirements for adhesives suitable for use in the plywood manufacturing industry. Classification of the adhesives, product information and requirements for pH of the mixed adhesive and bond quality of assemblies when tested dry and wet are laid down. Actual service conditions under which plywoods possessing various bond types can be used are defined.

This standard specifies requirements for adhesives suitable for use in the plywood manufacturing industry, the criterion for suitability being the ability of an adhesive to produce bonded plywood panels of defined types and quality.The standard sets out in tabular form (see Table l) the relationship between the recognized plywood bond types (A, B, C and D), the chemical types of adhesives normally used to produce these bond types, and the service conditions and performance test requirements applicable to the four types of bond.
