Description of ASTM-D2919 2007ASTM D2919 - 01(2007)Standard Test Method for Determining Durability of Adhesive Joints Stressed in Shear by Tension LoadingActive Standard ASTM D2919 | Developed by Subcommittee: D14.80 Book of Standards Volume: 15.06 ASTM D2919Significance and Use The combination of stress and moisture decreases the durability of most adhesive joints. Stresses in the presence of water or water vapor may cause some adhesive joints to fail at some small fraction of the stress required to break the dry joint. The time to failure for a given adhesive joint generally decreases with increasing stress, temperature, and relative humidity. This test method may be used as an accelerated screening test for assessing the durability of adhesive joints. It may be used to measure durability of adhesive joints exposed outdoors or to environmental conditions experienced by adhesive joints in service. The tests may also be used to determine the effects of various surface preparations or substrates on durabilities of adhesive joints. The durability performance of various adhesives may be compared by using this test method under uniform sets of conditions. To assess the overall durability of a given adhesive, lap-shear joints should be tested under a range of stress, relative humidity, and temperature. For a specific end use it may be possible to obtain the needed durability data using only one set of test conditions. 1. Scope 1.1 This test method covers data for assessing the durability of adhesive lap-shear joints while stressed in contact with air, air in equilibrium with certain solutions, water, aqueous solutions, or other environments at various temperatures. 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. Specific precautionary statements are given in . 1.2 The values stated in SI units are considered to be the standard. The values in parentheses are for information only.
