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 .

This test method is primarily comparative. We are confident that we have what you are looking for. The adherends and adhesive are likely to have different thermal and moisture coefficients of expansion. Related Polymer Shear Test Services: The test is applicable for determining adhesive strength, surface preparation parameters, and adhesive environmental durability.
Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D
Simple design can be used for a multitude of tensile applications Inexpensive and reliable. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Work Item s – proposed revisions of this standard.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Rated to 1 kN lbf Maximum specimen thicknesses from aetm mm to 50 mm 0. The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of tested systems.
GK Mechanical Vice Grip. The normal variation of temperature and moisture in the service environment causes the adherends and the adhesive to swell or shrink. By means of our adhesive testing expertise and modular product design, we will help find the testing asfm that is right for you.
Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D1002
Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: 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. The recommended lap shear specimen is ASTM D determines the shear strength of adhesives for bonding metals when tested on a single-lap-joint specimen. 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.
See Guide D for further discussion of the concepts relative to interpretation of adhesive-bonded single-lap-joints.
Need help or have a question? ASTM D is commonly used as a guideline for testing the strength of adhesives to bond metals. An electromechanical universal testing machine can be used to conduct a lap shear test. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, astmm and humidity chambers, furnaces, baths and custom solutions for unique applications. 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.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The test specimens are placed in the grips of a universal testing machine and pulled at 1.
The assembly is then cut into uniform width lap shear specimens. Inspection Validating the specifications, asfm and safety of your raw materials, products and assets.
The values given in parentheses are for information only. Metal thickness should be 1. 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. The misuse of strength values obtained from this test method as design-allowable stress d102 for structural joints could lead asmt product failure, property damage, and human injury.
Formally confirming that your products and services meet all trusted external and internal standards. The type of failure can be either adhesive the adhesive separates from one of the substrates or cohesive the adhesive ruptures within itself.

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. Historical Version s – view previous versions of 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.
