ASTM D1002 PDF

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 .

Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: 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. The test specimens are placed in the grips of a universal testing machine and pulled at 1.

The adherends and adhesive are likely to have different thermal and moisture coefficients of expansion.

ASTM D test procedure: Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of tested systems. However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability.

Assurance Testing Inspection Certification.

ASTM D Lap Shear Testing for Adhesively Bonded Metals

The recommended metal thickness is 1. 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 axtm adherends or by a different bonding process.

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. By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you. The assembly is then cut into uniform width lap shear specimens. Inspection Validating the specifications, astn and safety of your raw materials, satm and assets.

Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D

ASTM D determines the shear strength of adhesives for bonding metals when tested on a single-lap-joint specimen. An electromechanical universal testing machine can be used to conduct a lap shear test. 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.

Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D 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. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world.

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.

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.

Validating the specifications, value and safety of your raw materials, products and assets. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.

The test is applicable for determining adhesive strength, surface preparation parameters, and adhesive environmental durability. 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.

Have a question about conducting the test for this standard? Simple design can be used for a multitude of tensile applications Inexpensive and reliable. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. 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.
