1.1 This specification establishes performance levels for adhesives to be used in finger joints in nonstructural bondedlumber products. Such products include, but are not limited to, interior and exterior mouldings, window and door components or parts, and bonded-lumber panels. Adhesives that meet the requirements of the various performance classes are considered capable of providing an adequate bond for use under the conditions described for the class. This specification is to be used to evaluate adhesives as well as the adhesive bonds in the finger joints. See Section 5, Significance and Use, for limitations when using this specification to evaluate industrially manufactured finger joints. NOTE 1—This specification supersedes the finger-joint portion of the 1990 edition of Specification D3110.
