A universal testing machine is used to push the punch until shearing of the specimen occurs. Sources of Additional Information: Alternate Punch Shear Fixture Configurations. aztm
The lower 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. 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.

ASTM D TESTING FIXTURE
What is Third Party Certification and Accreditation for the food industry? Historical Version s – view previous versions of standard. Select from list below: The area of the sheared edge is equal to the circumference of the punch multiplied by the thickness of the specimen. Other non-standard, comparative-type punch shear test methods have also been developed.
This test method is intended as a comparative test, and not as a quantitative measure of the shear strength of the material. 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 TESTING FIXTURE
Moreover, 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. A male punch is then forced through the hole in the metal fixture causing shear along the edge of the hole.
The values given in parentheses are for information only.
However, a uniform shear stress state is not attained; severe stress concentrations occur at the edges of the punch. Shear strength testing is used to determine the load at which a plastic or film will yield when sheared between two metal edges.
