1.1 This specification establishes performance levels for adhesives to be used in finger joints in nonstructural bonded-lumber 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 , Significance and Use, for limitations when using this specification to evaluate industrially manufactured finger joints. Note 1This specification supersedes the finger-joint portion of the 1990 edition of Specification D 3110.
1.2 The following index is provided as a guide to the test methods in this specification:
The conditioning needed for various stages in the preparation of both types of specimens and for the exposure tests are given.Note 3
Specific guidelines for specimen size, exposure conditions, testing, calculation, and reporting are given for flexure specimens in Sections and , and for tension specimens in Sections and .
