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 .

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. The recommended lap shear specimen is Work Item s – proposed revisions of this standard. The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of tested systems. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

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. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Referenced Documents purchase separately The documents listed below are referenced within qstm subject standard but are not d102 as part of the standard.
Two metal plates are bonded together with adhesive and cured as specified. The adherends and adhesive are likely to have different thermal and moisture coefficients of expansion. This test method is primarily comparative. ASTM D requires testing for the following measurements:.
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. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.
