This standard is issued under the fixed designation D ; the number immediately 1 This lest imethod is under the jurisdiction of ASTM Committee D- 14 on. ASTM D is commonly performed to measure the shear strength of adhesives that are used to bond metals. Shear joints impose uniform stresses across the bond area which results in the highest possible joint strength. ASTM D is commonly performed to measure .

An electromechanical universal testing machine can be used to conduct a lap shear test. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Simple design can be used for a asgm of tensile applications Inexpensive and reliable.
The right testing machine and grips are important to consider due to the fact that the grips must align so that the applied force is sent through the centerline of the specimen. ASTM D determines the shear strength of adhesives for bonding metals when tested on a single-lap-joint specimen.

This testing standard can be used on single-lap-joint specimens and can be used asgm determine adhesive strength, surface preparation parameters and adhesive environmental durability. Work Item s – proposed revisions of this standard.
The problem of predicting joint behavior in a changing environment is even more difficult if a different type of adherend is used in a larger structural joint than was used in the small specimen.
Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D1002
G Mechanical Wedge Grip. However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability.
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 assembly is then cut into uniform width lap shear specimens.

ASTM D is commonly used as a guideline for testing the strength of adhesives to bond metals. The normal variation of temperature and moisture in the service environment causes the adherends and the adhesive to swell or shrink.
This test method is primarily comparative.
The test is applicable for determining adhesive strength, surface preparation parameters, and adhesive environmental durability. Even in small specimens, short-term environmental changes may induce internal stresses or chemical changes in the adhesive that permanently affect the apparent strength and other mechanical properties of the adhesive.
ASTM D Lap Shear Testing for Adhesively Bonded Metals
The grips used to secure the ends of the assembly must align so that the applied force is applied through the centerline of the specimen. The specimen failure should occur d10002 the adhesive, and not in the substrate — thus the metal thickness and the length of the overlap may be adjusted as necessary.

The misuse of strength values obtained from this test method as design-allowable stress values for structural joints could lead to product failure, property damage, and human injury. The test specimens are placed in the grips of a universal testing machine and pulled at 1.
