Standard Test Methods for Integrity of Adhesive Joints in Structural Laminated Wood Products for Exterior Use
4.1 The test is suitable for check testing properly selected samples from regular production or for determining the suitability of adhesives and bonding techniques for the production of joints for exterior service.
4.2 Vary the number of specimens taken from each member and the number of members selected for test depending on the total number of members involved and the purpose of the tests. It is advisable, however, to include at least three specimens in the test, with the specimens selected to represent the probable range of quality of the adhesive joints.
4.3 Adhesive joints at knots and knotty areas in general are not dependable under severe exposures. Disregard development of delamination at knots and do not include in the measurements or calculations.
1.1 These test methods cover an accelerated means of measuring the resistance to delamination of structural laminated wood members intended for exterior service.
1.2 These test methods are not intended as substitutes or replacements for the more severe test of resistance to delamination in Specification D2559.
1.3 Two test methods are included. Choice of test method depends on purpose of the test and available time to complete.
1.3.1 Test Method A—This test requires 3 days to complete and is a method for determining the suitability of adhesives and manufacturing techniques and equipment for production of joints adequate for exterior service.
1.3.2 Test Method B—This test requires approximately 121/2 h. (If excessive delamination occurs, the cycle is repeated). It is a quality-control type test for examining adhesive joint quality.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 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.
