(Test Method)Standard Test Method for Determining Durability of Adhesive Joints Stressed in Shear by Tension Loading
Standard Test Method for Determining Durability of Adhesive Joints Stressed in Shear by Tension Loading
SCOPE
1.1 This test method provides 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.
1.2 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 7.4. 1.3 The values stated in SI units are considered to be the standard. The values in parentheses ar for information only.
