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 adherends and adhesive are likely to have different thermal and moisture coefficients of expansion. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D
Simple design can be used for a multitude of tensile applications Inexpensive and reliable. ASTM D recommends that the lap shear specimen is We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
The assembly d102 then cut into uniform width lap shear specimens.
D102 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. 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. 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.
We are confident that we have what you are looking for. GK Mechanical Vice Grip. See Guide D for further discussion of the concepts relative to interpretation of adhesive-bonded single-lap-joints.
Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D Work Item s – proposed revisions of this standard. Have a question about conducting the test for this standard? ASTM D is commonly used as a guideline for testing the strength of adhesives to bond metals. The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of astk systems.
Two metal plates are bonded together with adhesive and cured as specified.
ASTM D Lap Shear Testing for Adhesively Bonded Metals
Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models. Record the maximum force applied. Inspection Validating the specifications, value and safety of your raw materials, products and assets.
By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 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 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 d100 the centerline of the specimen. Rated to 1 kN lbf Maximum specimen thicknesses from 10 mm to s1002 mm 0.
The values given in parentheses are for information only. 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 atsm and understanding of the joint and adhesive behaviors. 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.
