1.1 This test method is designed to evaluate adhesives for finger jointing lumber used in the manufacture of a variety of bonded structural wood products such as structural glued laminated timber. It tests the tensile strength of joints under the following treatments: dry with no treatment, wet after one vacuum-pressure soak treatment, and wet after cyclic boil-dry treatment.

1.2 This test method is intended neither for quality control as the test assemblies are selected for the absence of defects usually found in run-of-the-mill finger joints nor as a substitute for in-plant qualification of end joints, including full-scale joint tests.

Note 1:  This test method is specifically designed to evaluate adhesives for use in finger jointing lumber using small scale test specimens cut from carefully selected finger joint assemblies. In contrast, plant qualification and quality control require tests of full scale end joints selected randomly from production, designed to evaluate parameters beyond adhesive performance which affect the performance of the end use product.

1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.4  This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
