ASTM D covers punch-type shear tests used in determining the shear strength of test specimens of organic plastic sheets and molded disks in thicknesses from 1.
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. The results are expressed as shear strength and are given in the units of MPa or psi.
Other non-standard, comparative-type punch shear test methods have also been developed. The wstm end of the punch is then placed in the hole in the base plate lower left and the cover plate top is bolted on to hold the specimen securely in place. The area of the sheared edge is equal to the circumference of the punch multiplied by the thickness of the specimen.
Give one of d7322 application engineers a call today for help with creating the best budget and testing plan according to ASTM D The values given in parentheses are for information only. A universal testing machine is used to push the punch until shearing of the specimen occurs. Assurance Testing Inspection Certification.

ASTM D732 TESTING FIXTURE
There is no known ISO equivalent to this standard. It is intended for use as a materials screening and materials comparison test of plastics available in the form of sheets or molded disks.
Shear strength testing is used to determine the load at which a plastic or film will yield when sheared between two metal edges. Specimen thicknesses can range from 0. Wyoming Test Fixtures Inc. This specimen is clamped between the two hardened steel disks of the punch shown at the lower right of the photograph. Select from list below: Certification Formally confirming that your products and services meet all trusted external and internal standards.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
A male punch is then forced through the hole in the metal fixture causing shear along the edge of the hole. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Therefore, it is advisable to refer to that material specification before using this test method. Formally confirming that your products and services meet all trusted external and internal standards. However, it must be recognized that for d72 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.
We are confident that we have what you are looking for.

However, a uniform shear stress state is not attained; severe stress concentrations occur at the edges of the punch.
