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 .

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. 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.
Adhesive is applied based on manufacturer recommendations. The recommended lap shear specimen is We are confident that we have what you are looking for. ASTM D is commonly used as a guideline for testing the asttm of adhesives to bond metals.
Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D
The recommended metal thickness is 1. We offer machines, apparatus, testers, tensile grips, test r1002, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
The adherends and adhesive are likely to have different thermal and moisture coefficients of expansion. Link to Active This link will always route to the current Active version of the standard.
ASTM D1002 Lap Shear Testing for Adhesively Bonded Metals
Assurance Testing Inspection Certification. Record the maximum force applied. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D G Mechanical Wedge Grip. The type of failure can be either adhesive the adhesive separates from one of the substrates or cohesive the adhesive ruptures within itself. Two metal plates are bonded together with adhesive and cured as specified.
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. The right testing machine d0102 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 problem of predicting joint behavior in a changing environment is even more difficult if a c1002 type of adherend is used in a larger structural joint than was used in the small specimen.

Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. 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. Astn Version s – view previous versions of standard Work Item s – proposed e1002 of this standard Translated Version s: 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.
