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 .

Rated to 1 kN lbf Maximum specimen thicknesses from 10 mm to 50 mm 0. The test is applicable for determining adhesive strength, surface preparation parameters, and adhesive environmental durability. Related Polymer Shear Test Services: An electromechanical universal testing machine can be used to conduct astn lap shear test.

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.

ASTM D Lap Shear Testing for Adhesively Bonded Metals

Link to Active This link will always route to the current Active version of the standard. Adhesive is applied based on manufacturer recommendations. We are confident that we have what you are looking for. The problem of predicting joint r1002 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. Axtm D requires testing for the following measurements:.

Work Item s – proposed revisions of this standard. This test method is primarily comparative. 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. However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability. Formally confirming that your products and services meet all trusted external and internal standards.

Metal thickness should be 1.

Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D

Simple design can be used for a multitude of tensile applications Inexpensive and reliable. The adherends and adhesive are likely to have different thermal and moisture coefficients of expansion. The recommended metal thickness is 1. The recommended lap shear specimen is G Mechanical Wedge Grip. 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 values given in parentheses are for information only. By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for aatm. The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of tested systems. See Guide D for further discussion of the concepts relative to interpretation of adhesive-bonded single-lap-joints.

ASTM D1002 Lap Shear Testing for Adhesively Bonded Metals

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. The test specimens are placed in the grips of d1020 universal testing machine and pulled at 1.

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 d1002.

The type of failure can be either adhesive the adhesive separates from one of the substrates or cohesive the adhesive ruptures within itself. ASTM D is commonly d10002 as a guideline for testing the strength of adhesives to bond metals.
