ASTM D testing covers the punch-type shear test and is intended for asstm in determining the shear strength of test specimens of organic plastics in the form of sheets and molded disks in thicknesses from 0.
Moreover, the fact that the shear strength is calculated by dividing the load by the area of the sheared edge punch circumference X specimen thickness does not interpret as indicating the shear strength value so obtained is solely a material property, independent of thickness. Other non-standard, comparative-type punch shear test methods have also been developed. However, it must be recognized that for end-use applications there are likely to be many factors not taken into account in this test method, such as stress-concentrating geometries and rates of shear, which can profoundly affect the measured shear strength.

Wyoming Test Fixtures Inc. Shear strength results are important to designers of film and sheet products that tend to be subjected to shear loads, or in applications where applied crushing loads are a risk.
ASTM D732 – Shear Strength Testing of Plastics
Specimen thicknesses can range from 0. Moreover, the fact that the shear strength is calculated by dividing the load by the area of the shear strength is calculated by dividing d723 load by the area of the sheared edge circumference X thickness should not be interpreted as indicating that the shear d73 value so obtained is solely a material property, independent of thickness.
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. However, it must be recognized that for end-use application there may be many factors not taken into account in this test method, such as stress-concentrating geometrics and rates of shear, which can profoundly affect asm strength. 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.
Inspection Validating the specifications, value and safety of your raw materials, products and assets. Shear r732 testing is used to determine the load at which a plastic or film will yield when sheared between two metal edges. However, a uniform shear stress state is not attained; severe stress concentrations occur at the edges of the punch.

The shear force is simply calculated as the maximum force applied divided by the shear area punch circumference x specimen thickness. A universal testing machine is used to push the punch until shearing of the specimen occurs.
We are confident that we have what you are looking for. The test is performed by clamping a test sample attached to a 1-inch punch between two metal fixtures. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:. Shear strength obtained by a tool of the punch type is one of the recognized methods of comparing materials or obtaining data ast, engineering design.

By means of our plastic testing expertise and modular product design, we will help find the testing solution d723 is right for you. The results are expressed as shear strength and are given in the units of MPa or psi.
Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains xstm business processes. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Figure 2 shows two such fixtures. This test method is intended as a comparative test, and not as a quantitative measure of the shear strength of the material.
Have a question about conducting the test for this standard? For both fixtures, a specimen in the form of a bar of rectangular cross section is simply placed in a slot in the base and a flat-bottomed guillotine is pressed against the bar, shearing it into d723 pieces.
