This specification covers performance levels for adhesives to be used in laminate joints in nonstructural lumber products. Such products include, but are not limited to, interior and exterior mouldings, window and door components or parts, and bonded lumber panels. This specification is to be used to evaluate adhesives as well as the adhesive bonds in nonstructural-glued-lumber products. Dry test, soak test, elevated temperature test, boil test, and vacuum pressure test shall be performed to meet the requirements prescribed. The precision and bias of exposure condition shall be tested to meet the requirements prescribed.
