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 type of failure can be either adhesive the adhesive separates from one of the substrates or cohesive the adhesive ruptures within itself. Validating the specifications, value and safety of your raw materials, products and assets. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
The normal variation of temperature and moisture in the service environment causes the adherends and the adhesive to swell or shrink. ASTM D test procedure: Assurance Testing Inspection Certification. 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 recommended lap shear specimen is The adherends and adhesive are likely to have different thermal and moisture coefficients of expansion.

Link to Active This link will always route to the current Active version of the standard. Two metal plates are bonded together with adhesive and cured as e1002.
Simple design can be used for a multitude of tensile applications Inexpensive and reliable.
Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: The values given in parentheses are for information only. The recommended metal thickness is 1.
However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability. 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 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.

Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D1002
The specimen failure should occur in the adhesive, and not in the substrate — thus the metal thickness astmm the length of the overlap may be adjusted as necessary. The right testing machine and grips are important to consider due to the d1020 that the grips must align so that the applied force is sent through the centerline of the specimen. Historical Version s – view previous versions of standard. Auditing Consulting Sourcing Training. This testing standard can be used on single-lap-joint specimens and can be used to determine adhesive strength, surface asym parameters and adhesive environmental durability.
Inspection Validating the specifications, value and safety of your raw materials, products and assets. 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.
ASTM D1002 Lap Shear Testing for Adhesively Bonded Metals
The test is applicable for determining adhesive strength, surface preparation parameters, and adhesive environmental durability. 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 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.
G Mechanical Wedge Grip. ASTM D recommends that the lap shear specimen is This test method is primarily comparative. Single-lap tests may be used for comparing and selecting adhesives or satm 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.
