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 grips used to secure the ends of the assembly must align so that the applied force is applied through the centerline of the specimen. 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.
Aztm to Active This link will always route to the current Active version of the standard.
The values given in parentheses are for information only. 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: Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. 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.
The test specimens are placed in the grips of a universal testing machine and pulled at 1. Auditing Consulting Sourcing Training.
Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D1002
The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of tested systems. See Guide D for further discussion of the concepts relative to interpretation of adhesive-bonded single-lap-joints. Load ratings of 20 kN and 50 kN 4, lbf and 11, lbf Maximum specimen thickness of 16 mm 0. GK Mechanical Vice Grip.
Validating the specifications, axtm and safety of d10022 raw materials, products and assets. The normal variation of temperature and moisture in the service environment causes the adherends and the adhesive to swell or shrink.
Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D
The type of failure can be either adhesive the adhesive separates from one of the substrates or cohesive the adhesive ruptures within itself. However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
The apparent shear strength measured with a single-lap specimen is not suitable for determining design-allowable stresses for designing atm joints that differ in any manner from the joints tested without thorough analysis and understanding of the joint and adhesive behaviors.
Metal thickness should be 1. Assurance Testing Inspection Certification. Historical Version s – view previous versions of standard. Two metal plates are bonded together with adhesive and cured as specified.
ASTM D determines the shear strength of adhesives for bonding metals when tested on a single-lap-joint specimen. 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. Adhesive is applied based on manufacturer recommendations.

Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
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. This test method is primarily comparative.
Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options aatm adjustable test space Affordable testing option for tension, compression, bend, peel and much more.
Give one of our application engineers a call today for help with creating the best budget and testing plan according to D102 D ASTM D recommends that the lap shear specimen is 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.
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. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths f1002 custom solutions for unique applications. The misuse of strength values obtained from this test method as design-allowable stress values for structural joints could lead to product d11002, property damage, and human injury.
Need help or have a question? By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you. The recommended lap shear specimen is ASTM D astn commonly used as a guideline for testing the strength of adhesives to bond metals.
Certification Formally confirming that your products and services meet all trusted external and internal standards. Related Polymer Shear Test Services: 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. The test is applicable for determining adhesive strength, surface preparation parameters, and adhesive environmental durability.
G Mechanical Wedge Grip. Send us a request Wilton UK: Inspection Validating the specifications, value and safety of your raw materials, products and assets. 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. Simple design can be used for a multitude of tensile applications Inexpensive and reliable.
