significance And Use:

scope:

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
