A universal testing machine is used to push the punch until shearing of the specimen occurs. 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 shear strength. Have a question about conducting the test for this standard?
ASTM D – Shear Punch Fixture
Formally confirming that your products and services meet all aetm external and internal standards. The results are expressed as shear strength and are given in the units of MPa or psi.
Certification Formally confirming that your products and services meet all trusted external and internal standards.

D7332, the fact that the shear strength is calculated by dividing the load by the area of the shear strength is calculated by dividing the load by the area of the sheared edge circumference X thickness should not be interpreted as indicating that the shear strength 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 asttm limitations prior to use.
Therefore, it is advisable to refer to that material d7732 before using this test method. This test method is intended as a comparative test, and not as a quantitative measure of the shear strength of the material. The shear force is simply calculated as the maximum force applied divided by the shear area punch circumference x specimen thickness. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:.
Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: ASTM D test procedure: Specimen thicknesses can range from 0.
Auditing Consulting Sourcing Training. Alternate Punch Shear Fixture Configurations. It is intended for use as a materials screening and materials comparison test of plastics available in the form of sheets or molded disks.
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 three pieces.
Shear strength obtained by a tool of the punch type is one of the recognized methods of comparing materials or obtaining data for engineering design. 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. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
The shear strength is calculated by dividing the force required to shear the specimen by the area of the sheared edge. The test is performed by clamping a test sample attached to a 1-inch punch between two metal fixtures. By means of our plastic testing expertise and modular product design, we will help find the testing solution that is right aetm you.
Shear Strength Test by ASTM D732
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. ASTM D testing covers the punch-type shear test and is intended for use in determining the shear strength of test specimens of organic plastics in the form of sheets and molded disks in thicknesses from 0. As a materials screening test it does have the advantages of requiring a simple specimen and utilizing a simple test procedure.
Inspection Validating the specifications, value and safety of your raw materials, products and assets.
ASTM D TESTING FIXTURE
Other non-standard, comparative-type punch shear test methods have also been developed. A male punch is then forced through the hole in the metal fixture causing shear along the edge of the hole. ASTM D specifies constant rate of extension testing machine universal test machine. However, a axtm shear stress state is not attained; severe stress concentrations occur at the edges of the punch.
Select from list below: Shear strength obtained by a tool of the punch type is one of the recognized methods of comparing materials or obtaining data for engineering design.

ASTM D732 – Shear Strength Testing of Plastics
Shear strength testing is used to determine the load at which asm plastic or film will yield when sheared between two metal edges. Wyoming Test Fixtures Inc. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.
