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 .

Metal thickness should be 1.
The assembly is then cut into uniform width lap shear specimens. Assurance Asm you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
The grips used to secure the ends of the assembly must align so that the applied force is applied through the centerline of the 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.

Load ratings of 20 kN and 50 kN 4, lbf and 11, lbf Maximum specimen thickness of 16 mm 0. Global Reach Intertek is the industry leader with over 42, people in 1, asrm in over countries.
Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D
Have a question about conducting the test for this standard? Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. 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.
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
We are confident that we have what you are looking for. This test method is primarily comparative. 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. ASTM D determines the shear strength of adhesives for bonding metals when tested on a aatm specimen. Rated to 1 kN lbf Maximum specimen thicknesses from 10 mm to 50 mm 0.
See Guide D for further discussion of the s1002 relative to interpretation of adhesive-bonded single-lap-joints. ASTM D requires testing for the following measurements:. 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 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 test is applicable for determining adhesive strength, surface preparation parameters, and adhesive environmental durability. ASTM D recommends that the lap shear specimen is The values given in parentheses are for information only.
Force range of 5 asym 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.

Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D1002
The adherends and adhesive are likely to have different thermal and moisture coefficients of expansion. Auditing Consulting Sourcing Training. 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 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.
Two metal plates are bonded together with adhesive and cured as specified. 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.
Link to Active This link will always route to the current Active version of the standard. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Zstm, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability. The type of failure can be either adhesive the adhesive separates from one of the substrates or cohesive the adhesive ruptures within itself. Historical Version s – view previous versions of standard.
The misuse of strength values obtained r1002 this test method as design-allowable stress values for structural joints could lead to product failure, property damage, and human injury.
ASTM D Lap Shear Testing for Adhesively Bonded Metals
Send us a request Wilton UK: The specimen failure should occur in the adhesive, and d10002 in the substrate — thus the metal thickness and the length of the overlap may be adjusted as necessary. It is the responsibility of the user of this standard d002 establish appropriate safety and health practices and determine the applicability of regulatory limitations d002 to use.
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.
The test specimens are placed in the grips of a universal testing machine and pulled at 1. 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. The recommended lap shear specimen is The normal variation of temperature and moisture in the ashm environment causes the adherends and the adhesive to swell or shrink.
