- Scope
5.1 This test method evaluates the performance of the adhesive in laminated wood as measured by resistance to creep under static load.
5.2 Test results from the evaluation of adhesive creep resistance, under designated environmental conditions of the test, provide a measure of the adhesive’s ability to withstand constant loading over a relatively long period of time.
5.3 Creep measured with this test method is normally used in conjunction with specifications such as, but not limited to Specification D2559 and CSA O112.9 to confirm suitability of an adhesive to resist creep under designed loads when subjected to specific levels of stress, load duration and environmental conditions.
1.1 This test method covers the determination of creep properties of structural adhesives in wood-to-wood bonds when a standardized specimen is subjected to shearing stresses at various levels of static load, constant temperature, and relative humidity. Apparatus and procedures are provided for shear deformation (creep) of adhesive bonds under static load. This test method is used under the indicated conditions to evaluate resistance to creep properties of a structural wood adhesive.
1.2 The test method is used to evaluate creep performance of adhesives suitable for the bonding of wood, including treated wood, into structural wood products for general construction, marine use, or for other uses where a high-strength general construction, creep-resistant, durable adhesive bond is required. Individual block shear specimens are prepared from adhesively bonded laminations, subjected to a constant load under various combinations of temperature and relative humidity, and the amount of creep measured.
1.3 Creep of structural wood adhesives as measured by this test method may not be comparative to other ASTM methods and is limited to the conditions of the test and procedures contained herein.
1.4 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.
1.5 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.
