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 .

ASTM D Lap Shear Testing for Adhesively Bonded Metals

Send us a request Wilton UK: 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. Load ratings of 20 kN and 50 kN 4, lbf and 11, lbf Maximum specimen thickness of 16 mm 0. 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.

Even in small specimens, short-term environmental changes may induce internal stresses or chemical changes in the adhesive that permanently affect the awtm strength and other mechanical properties of the adhesive.

Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D1002

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. Work Item s – proposed revisions of this standard.


The type of failure can be either adhesive the adhesive separates from one of the substrates or cohesive the adhesive ruptures within itself. The values given in parentheses are for information only. 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. ASTM D requires testing for the following measurements:.

ASTM D test procedure: G Mechanical Wedge Grip. The test specimens are placed in the grips of a universal testing machine and pulled at 1. Auditing Consulting Sourcing Training. Inspection Validating the specifications, value and safety of your raw materials, products and assets. Simple design can be used for a multitude of tensile applications Inexpensive and reliable.

Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D

The test method has found applications in controlling surface preparations, primer, and adhesive systems astj determining strength properties of tested systems. By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you.

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. Record the maximum force applied. Adhesive is applied based on manufacturer recommendations.

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. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

ASTM D1002 Lap Shear Testing for Adhesively Bonded Metals

The recommended metal thickness is 1. ASTM D determines the shear strength of adhesives for bonding metals when tested on a single-lap-joint specimen. 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.

We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, s1002, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

The assembly is then cut into uniform width lap shear specimens. We are confident that we have what you are looking for. ASTM D recommends that the lap shear specimen is Assurance Testing Inspection Certification.
