The apparent shear strength of single-lap-joint adhesively bonded metal specimens may be tested by the tension loading procedure described in ASTM D1002-10. The apparent shear strength of an adhesive obtained from a given small single-lap specimen may differ from that obtained from a joint made with different adherends or by a different bonding process. The strength of the adhesives used in the bonding process depends greatly upon the curing process they underwent. Variations in this process will alter the strength of the adhesives. This test method is primarily comparative. However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability.
Applicable Testing Standards
