Specimen thicknesses can range from 0. The results are expressed as shear strength and are given in the units of MPa or psi.

ASTM D732 Shear Punch Test Equipment for Plastics

However, a uniform shear stress state is not attained; severe stress concentrations occur at the edges of the punch. This test method is intended as a comparative test, and not as a quantitative measure of the shear strength of the material.

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 specifies constant rate of extension testing machine universal test machine. Link to Active This link asstm always route to the current Active version of the standard.

Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.

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.

Assurance Enabling you to identify and mitigate astmm intrinsic risk in your operations, supply chains and business processes. 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.

Related Polymer Shear Test Services: 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. 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.

The area of the sheared edge is equal to the circumference of the punch multiplied by the thickness of the specimen.

Shear Strength Test by ASTM D732

As a materials screening test it does have the advantages of requiring a simple specimen and utilizing a simple test procedure. It is intended for use as a materials screening and materials comparison test of plastics available in the form of sheets or molded disks.
