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. Alternate Punch Shear Fixture Configurations.

Inspection Validating the specifications, value and safety of your raw materials, products and assets. This specimen is clamped between the two hardened steel disks of the punch shown at the lower right of the photograph.

Shear Properties – ASTM D732

The area of the sheared edge is equal to the circumference of the punch multiplied by the thickness of the specimen. ASTM D test procedure: The shear force is simply calculated as the maximum force applied divided by the shear area punch circumference x specimen thickness.

This test method is intended as a comparative test, and not as a quantitative measure of the shear strength of the material. The specimens are usually 2 inich diameter discs or 2 inch squared plates and thickness ranging between 0.

As a materials screening test it does have the advantages of requiring a simple specimen and utilizing a simple test procedure. Historical Version s – view previous versions of standard.

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, ashm can profoundly affect shear strength. The shear strength is calculated by dividing the force required to shear the specimen by the area of the sheared edge.

Auditing Consulting Sourcing Training. However, it must be recognized that for end-use applications there are likely to be many factors not taken astj account e732 this test method, such as stress-concentrating geometries and rates of shear, which can profoundly affect the measured shear strength.

The values given in parentheses are for information only. Shear strength testing is used to determine the load at which a plastic or film will yield when sheared between two metal edges. Moreover, the fact that the shear strength is calculated by dividing the load by the area f732 the shear strength is calculated by dividing the load by the area of the sheared edge circumference X thickness should d32 be interpreted as indicating that the shear strength value so obtained is solely a d7332 property, independent of thickness.

Specimen thicknesses can range from 0. Need help or have a question? Evaluating how your products and aatm meet and exceed quality, safety, sustainability and performance standards.

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.

A male punch is then forced through the hole in the metal fixture causing shear along the edge of the hole. It is intended for use as a materials screening and materials comparison test of plastics available in the form of sheets or molded disks.

However, a uniform shear stress state is not attained; severe stress concentrations occur at the edges of the punch. Therefore, it is advisable to refer to that material specification before using this test method.
