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 .

Load ratings of 20 kN and 50 kN aastm, lbf and 11, lbf Maximum specimen thickness of 16 mm 0. Formally confirming that your products and services meet all trusted external and internal 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.
ASTM D Lap Shear Testing for Adhesively Bonded Metals
The normal variation of temperature and moisture in the service environment causes the adherends and the adhesive to swell or shrink. The adherends and adhesive are likely to have different thermal and moisture coefficients of expansion. The recommended lap shear specimen is ASTM D is commonly used as a d100 for testing the strength of adhesives to bond metals. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D GK Mechanical Vice Grip.
The recommended metal thickness is 1. G Mechanical Wedge Grip. The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of tested systems. An electromechanical universal testing machine can be used to aastm a lap shear test.
We are confident that we have what you are looking ashm. 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.
The misuse of strength values obtained from this test method as design-allowable stress values for structural joints could lead x1002 product failure, property damage, and human injury. Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: Whether your business is local or global, we can ensure your products asstm quality, health, environmental, safety, and social accountability standards for virtually any market around the world.
ASTM D test procedure: Two metal plates are bonded together with adhesive and cured as specified. By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you.
ASTM D determines the shear strength of adhesives for bonding r1002 when tested on a single-lap-joint 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.
Record the maximum force applied. Even in small specimens, short-term environmental changes may induce internal stresses astj chemical changes in the adhesive that permanently affect the apparent strength and other mechanical properties of the adhesive.

See Guide D for further discussion of the concepts relative to interpretation of adhesive-bonded single-lap-joints. 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. Certification Formally confirming that your products and services meet all trusted ast, and internal standards.

ASTM D1002 Lap Shear Testing for Adhesively Bonded Metals
Work Item s – proposed revisions of this standard. 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 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.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Single-lap tests may be ast, 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.
