This test method provides reasonably accurate information with regard to the ability of UV curing adhesives to withstand torsional shearing forces. It may be used to determine the effect of environment on torsional shear strength.
1.1 This test method covers the simplistic comparison of strengths of glass/metal joints when the adhesive is cured by ultraviolet (UV) radiation and standard specimens are used and tested under specified conditions of preparation, radiation, and load.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.
1.3 This test method involves torque loading UV-bonded hexagonal metal blocks to glass plates.
1.4 This test method may be used to obtain comparative torque strength-to-failure data for other bonded joint systems, radiation cured or not.
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.
