Scope
1.1). These finger joints were prepared using previously certified adhesives in cooperation with a manufacturer or equipment supplier who had the necessary finger-joint cutter and assembly equipment. These finger joints may vary in geometry and length from manufacturer to manufacturer, and this variation could affect the performance of the bonded-finger-joint assembly.5 (See 12.1, 12.4, and 12.5.) Fig. 3 depicts a sample finger-joint configuration.

5.2.1 When changes are made in the design of the industrially manufactured finger joint, the new design should be compared to a control design that has been used successfully.

5.3 An industrially manufactured finger joint should be evaluated using the requirements for compliance with this specification, in accordance with 4.1. When this specification is used to evaluate specimens made from field-manufactured assemblies, the results may not compare favorably with those run on specimens made from laboratory-made assemblies.

5.4 Test requirements are provided to determine if the adhesive is suitable for dry use or wet use.

5.5 The dry test and exposure conditions and treatments are to evaluate adhesives used in nonstructural finger joints for typical service conditions.

5.5.1 The 220??F (104??C) test, a more severe test, is designed to evaluate the product after exposure to short-term elevated-temperature conditions. This test is intended to simulate conditions that might be experienced in transit, further processing, or in-service conditions.

Note 4???These typical service conditions could include stress and time under stress, as well as elevated temperature.
