Standard Test Method for Evaluating Structural Adhesives for Finger Jointing Lumber

Importancia y uso:

4.1 This test method is specifically designed to measure the performance of adhesives in finger joints manufactured under production line conditions.

4.1.1 The test method can be adapted to evaluate the adhesive performance of laboratory produced finger joints using commercial finger joint cutting heads with finger joints produced following the adhesive manufacturers recommendations. The conditions under which the finger joints were produced, including any limitations, are to be reported in 9.1.2.2 (see Note 2).

Note 2: If laboratory prepared finger joints are to be produced, record details related to adhesive used, its preparation, application to the cut finger joint, appropriate bonding parameters and limitations in the production of the finger joint assemblies.

4.2 The results of the test method may be used to certify an adhesive as suitable for finger jointing lumber under production line conditions where the intended end use of the finger jointed lumber may be in a variety of bonded structural wood products.

4.2.1 When the test results are to be used for certification of an adhesive a standard wood species shall be used.

4.2.1.1 Standard species may be found in Table 1 of Specification D2559.
