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 .

The apparent shear strength measured with a single-lap specimen is not suitable for determining design-allowable stresses for designing structural joints that differ in any manner from the joints tested without thorough analysis and understanding of the joint and adhesive behaviors.

Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains asm business processes. The assembly is then cut into uniform width lap shear specimens. ASTM D determines the shear strength of adhesives for bonding metals when tested on a single-lap-joint specimen. Two metal plates are bonded together with adhesive and cured as specified. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.
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. ASTM D test procedure: Adhesive is applied based on manufacturer recommendations. Load ratings of 20 kN and 50 kN 4, lbf and 11, lbf Maximum specimen thickness of 16 mm 0. The recommended lap shear specimen is The right testing machine and grips are important d1020 consider due to the fact that the grips must align so that the applied force is sent through the centerline of the specimen.
Related Polymer Shear Test Services: See Guide D for further discussion astj the concepts relative to interpretation of adhesive-bonded single-lap-joints. This test method is primarily comparative.
Single-lap tests may be used for comparing and selecting adhesives or bonding processes for susceptibility to fatigue and environmental changes, but such comparisons must be made with great caution since different adhesives may respond differently in different joints.

Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. Simple design can be used for a multitude of tensile applications Inexpensive and reliable.
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. The recommended metal thickness is 1. However, 1d002 does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability.

Validating the specifications, value and safety of your raw materials, products and assets. The specimen failure should occur in the adhesive, and not in the substrate — thus the metal thickness and the length of the overlap may be adjusted as necessary. We are confident that we have what you are looking for. The values given in parentheses are for information only.
The test specimens are placed in the grips of a universal testing machine and pulled at 1.
