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
Adhesive is applied based on manufacturer recommendations. 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.
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 recommends that the lap shear specimen is Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Auditing Consulting Sourcing Training. 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.

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.
Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: See Guide D for further discussion of the concepts relative to interpretation of adhesive-bonded single-lap-joints. The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of tested systems.
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 is commonly used as a guideline for testing the strength of adhesives to bond metals. 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.
Send us a request Wilton UK: Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. The normal variation of temperature and moisture in the service environment causes the adherends and the adhesive to swell or shrink. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. ASTM D test procedure: 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.
