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.
Sstm D is commonly used as a guideline for testing the strength of adhesives to bond metals. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Load ratings of 20 kN and 50 kN d102, lbf and 11, lbf Maximum specimen thickness of 16 mm 0. ASTM D requires testing for the following measurements:. This testing standard can be used on single-lap-joint specimens and can be used to determine adhesive strength, surface preparation parameters and adhesive environmental durability.
Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D1002
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Link to Active This link will always route to the current Active version of the standard.
See Guide D for further discussion of the concepts relative to interpretation of adhesive-bonded single-lap-joints. 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. Need help or have a question? Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: 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.
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. The recommended lap shear specimen is G Mechanical Wedge Grip.
Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable testing option for tension, compression, bend, peel and much more.
ASTM D Lap Shear Testing for Adhesively Bonded Metals
ASTM D recommends that the lap shear specimen is Whether your business is local or global, we can xstm your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.
The assembly is then cut into uniform width lap shear specimens. The adherends and adhesive are likely to have different thermal and moisture coefficients of expansion.
The values given in parentheses are for information only. GK Mechanical Vice Grip. 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 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. By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you. Two metal plates are bonded together with adhesive and cured as specified.
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. 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. We are confident that we have what you are looking for.
ASTM D1002 Lap Shear Testing for Adhesively Bonded Metals
Rated to 1 kN lbf Maximum specimen thicknesses from 10 mm to 50 mm 0. Have a question about conducting the test for this standard?
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. The test specimens are placed in the grips of a universal testing machine and pulled at 1. 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.
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. ASTM D determines the shear strength of adhesives for bonding metals when tested on a single-lap-joint specimen.
Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D
Historical Version s – view previous versions of standard. The recommended metal thickness is 1. 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 test procedure: Assurance Testing Inspection Certification. The type of failure can be either adhesive the adhesive separates from one of the substrates or cohesive the adhesive ruptures within itself. Metal thickness should aetm 1. Simple design can be used for a multitude of tensile applications Inexpensive and reliable. The test is applicable for determining adhesive strength, surface preparation parameters, and adhesive environmental durability. Formally confirming that your products and services meet all trusted external and internal standards.
Validating the specifications, value and safety of your raw materials, products and assets. Send us a request Wilton UK: However, it does have application as a discriminator in determining d1020 in adherend surface preparation parameters and adhesive environmental durability.
