Shear Strength Test by ASTM D732
Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world. Specimen thicknesses can range from 0. It is intended for use as a materials screening and materials comparison test of plastics available in the form of sheets or molded disks.
ASTM D test procedure: The values given in parentheses are for information only. Touchstone Research Laboratory, Ltd.
Validating the specifications, value and safety of your raw materials, products and assets. Other non-standard, comparative-type punch shear test methods have also been developed. Assurance Enabling you to identify and mitigate the intrinsic risk in your awtm, supply chains and business processes.
Select from list below: As a materials screening test it does have the advantages of requiring a simple specimen and utilizing a simple test procedure.
Shear Strength Test by ASTM D
Certification Formally confirming that your products and services meet all trusted external and internal standards. The area of the sheared edge is equal to the circumference of the punch multiplied by the thickness of the specimen.
A male punch is asttm forced through the hole in the metal fixture causing shear along the edge of the hole. There is no known ISO equivalent to this standard. We are confident that we have what you are looking for. Inspection Validating the specifications, value and safety of your raw materials, products and assets.
Related Polymer Shear Test Services: Historical Version s – view previous versions of standard. 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.
Figure 2 shows two such fixtures. The lower end of the punch is then placed in the hole in the base plate v732 left and the cover plate top v732 bolted on to hold the specimen securely in place.
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 d32.
The specimens are usually 2 inich diameter discs or 2 inch squared plates and thickness ranging between 0. Shear strength testing is used to determine the load at which a plastic or film will yield when sheared between two metal edges.
Therefore, it is advisable to refer to that material specification before using this test method.

The shear force is simply calculated as the maximum force applied divided by the shear area punch circumference x specimen thickness.
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.
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. Alternate Punch Shear Fixture Configurations.
