specifications use a single lap joint (lap shear) specimen to determine the shear strength of adhesives. If you are going to perform this test, you should read the entire specification from ASTM. This is a quick summary to decide if this test is right for you, and to point out what equipment you need to perform the test.
These adhesives can have different properties depending on their volatile and non-volatile contents. The standards help to identify these properties which include viscosity, adhesion, shear strength, and shear modulus. The adhesives are utilized to form bonds or joints between adherend materials which can be metal, wood, or plastic.
This test is similar to ASTM D3163 which is for adhesives that bond rigid plastic substrates, and also ASTM D3164 which is for plastic adhesives that are used to bond both plastic and metal substrates. All three of these specifications use a single lap joint (lap shear) specimen to determine the shear strength of adhesives.
Shear adhesion, or holding power, is one of the most important pressure sensitive adhesives (PSA) performances. Shear adhesion is the ability of a tape to resist the static forces applied in the same plane as the backing.

Learn about adhesive testing and the material testing solutions we provide within adhesive testing.
These values include shear strength, compressive strength, flexural strength, and peel strength among others. Shear Strength. Shear strength, in regards to epoxy adhesives, are common values used to portray the strength of epoxy. The most common of the shear strength values is lap shear strength. Lap shear strength is tested using ASTM method ...
Lap Shear Testing of Adhesives Master Bond epoxies exhibit outstanding physical strength properties for high performance bonding, sealing, coating, potting and encapsulation. There are several key strength properties that may be incorporated in our epoxy adhesive formulations: cleavage, compressive, flexural, peel, tensile, and shear.
some cases the limited strength of the adhesive. Within a European CRAFT research project on “standards, measurements and testing”, a new shear test method was developed to characterize the mode and value of failure of thermally sprayed layers in a more reliable and less limited manner.
