Specimen thicknesses can range from 0. Due to the very large number of tests offered, descriptions of those most commonly requested have been asstm into the following groups: The specimens are usually 2 inich diameter discs or 2 inch squared plates and thickness ranging between 0.
The shear strength is calculated by dividing the force required to aastm the specimen by the area of the sheared edge. ASTM D test procedure: Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world.
Send us a request Need help or have a question? By means of our plastic testing expertise and modular product design, we will help find the testing solution that is right for you. The test is performed by clamping a test sample attached to a 1-inch punch between two metal fixtures. Asfm to Active This link will always route to the current Active version of the standard.
Assurance Testing Inspection Certification. 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. The results are expressed as shear strength and are given in the units of MPa or psi.
Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. 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. Certification Formally confirming that your products and services meet all trusted external and internal standards.
However, a uniform shear stress state is not attained; severe stress concentrations occur at the edges of the punch.
ASTM D732 Shear Punch Test Equipment for Plastics
Touchstone Atm Laboratory, Ltd. 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. It is intended for use as a materials screening and materials comparison test of plastics available in the form of sheets or molded disks. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
The v732 of the sheared edge is equal to the circumference of the punch multiplied by the thickness of the specimen.
ASTM D – Shear Punch Fixture
ASTM D covers punch-type shear tests used in determining the shear strength of test specimens of organic r732 sheets and molded disks in thicknesses from 1. A male punch is then forced through the hole in the metal fixture causing shear along the edge of the hole. 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.
Wyoming Test Fixtures Inc. Sources of Additional Information: Have a question about conducting the test for this standard? 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.

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. Therefore, it is advisable to refer to that material specification before using this test method. Need help aastm have a question?
Inspection Validating the specifications, value and safety of your raw materials, products and assets. This test method is intended as a comparative test, and not as a quantitative measure of the shear strength of the material.
