ASTM D3163 is a tensile test used to measure the adhesive lap-shear strength of bonded rigid plastics.This testing standard is very similar to ISO 4587 and EN 1465, with the difference being that ASTM D3163 is used specifically to test adhesives applied to rigid plastics. To perform this test, a shear stress is applied to the specimen at a rate of 8.3 to 9.7 MPa per minute and the breaking force and shear strength are reported.
