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 7d32 measured shear strength.
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. 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 test procedure: Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.
Shear Strength Test by ASTM D732
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. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The values given in parentheses are for information f732.
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. 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.
Other non-standard, comparative-type punch shear test methods have also been developed.
ASTM-D – Grip-Engineering
Shear 7d32 obtained by a tool of the punch type is one of the recognized methods of comparing materials or obtaining data for engineering design. Validating the specifications, value and safety of your raw materials, products and assets.
Shear strength obtained by a tool of the punch type is one of the recognized methods of comparing materials or obtaining data aastm engineering design. Need help or have a question?
The test is performed by clamping a test sample attached to a 1-inch punch between two metal fixtures. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.
Send us a request Need help ast have a question? Certification Formally confirming that your products and services meet all trusted external and internal standards. Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable testing option for tension, compression, bend, peel and much more. This test method is intended as a comparative test, and not as a quantitative measure of the shear strength of the material.
A universal testing machine is used to push the punch until shearing of the specimen occurs. This specimen asstm clamped between the two hardened steel disks of the punch shown at the lower right of the photograph.

Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: Figure 2 shows two such fixtures. The shear strength is calculated by dividing the force required to d7322 the specimen by the 7d32 of the sheared edge.

Shear strength testing is used to determine the load at which a plastic or film will yield when sheared between two metal edges. Related Polymer Shear Test Services: By means of our plastic testing expertise and modular product design, we will help find the testing solution that is right for you. Wyoming Test Fixtures Inc. As a materials screening test it does have the advantages of requiring a simple specimen and utilizing a simple test procedure.
A male punch is then forced through the hole in the metal fixture causing shear along the edge of the hole. The specimens are usually 2 inich diameter discs or 2 inch squared plates and thickness ranging between 0. 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.
