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 D1002 Lap Shear Testing for Adhesively Bonded Metals
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.
Certification Formally confirming that your products and services meet all trusted adtm and internal standards. Metal thickness should be 1.
The recommended metal thickness is 1.
Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D
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. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
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. 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.
ASTM D test procedure: Assurance Enabling you to identify and mitigate the intrinsic risk in your satm, supply chains and business processes. ASTM D recommends that the lap shear specimen is Inspection Validating the specifications, value and safety aztm your raw materials, products and assets.
Referenced Documents purchase separately The documents d10002 below are referenced within the subject standard but are not provided as part of the standard. Two metal plates are bonded together with adhesive and cured as specified. The test specimens are placed in the grips of a universal testing machine and pulled at 1.
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. 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. 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.
Rated to 1 kN lbf Maximum specimen thicknesses from 10 mm to 50 mm 0. 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. The type of failure can be either adhesive the adhesive separates from one of the substrates or cohesive the adhesive ruptures within itself.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. An electromechanical universal testing machine can be used to conduct a lap shear test. G Mechanical Wedge Grip.

ASTM D requires testing for the following measurements:. The normal variation of temperature and moisture in the service environment causes the adherends and the adhesive to swell or shrink.
