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 .

Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Inspection Validating the specifications, value and safety of your raw materials, products and assets. ASTM D test procedure: We are confident that we have what you are looking for.
Load ratings of r1002 kN and 50 kN 4, lbf and 11, lbf Maximum specimen thickness of 16 mm 0. 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.
The assembly is then cut into uniform width lap shear specimens. 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.
This test method is primarily comparative.

ASTM D 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, wstm human injury. 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 recommended metal thickness is 1. Metal d102 should be 1. The recommended lap shear specimen is ASTM D determines the shear strength of adhesives for bonding metals when tested on a single-lap-joint specimen.

ASTM D1002 Lap Shear Testing for Adhesively Bonded Metals
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. Assurance Testing Inspection Certification.
Formally confirming that your products and services meet all trusted external and internal standards. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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 requires testing for the following measurements:. The test specimens are placed in the grips of a universal testing machine and pulled at 1. Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: Certification Formally confirming that your products and services meet all trusted external and internal standards.
The adherends and adhesive are likely to have different thermal and moisture coefficients of expansion.
Rated to 1 kN aetm Maximum specimen thicknesses from 10 mm to 50 mm 0. Historical Version s – view previous versions of standard.
The grips used astk secure the ends of the assembly must align so that the applied force is applied through the centerline of the specimen. An electromechanical universal testing machine can be used to conduct a lap shear test. The test is applicable for determining adhesive strength, surface preparation parameters, and adhesive environmental durability. D102, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability.
The normal variation of temperature and moisture satm the service environment causes the adherends and the adhesive to swell or shrink. The type of failure can be either adhesive the adhesive separates from one of the substrates or cohesive the adhesive ruptures within itself.
