This specimen is clamped between the two hardened steel disks of the punch shown at the lower right of the photograph.
There is no known ISO equivalent to this standard. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Wyoming Test Fixtures Inc.
Specimen thicknesses can range from 0. Send us a request Wilton UK: Touchstone Research Laboratory, Ltd. Shear d72 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.
Formally confirming that your products and services meet all trusted external and internal standards. Figure 2 shows two c732 fixtures. Shear strength testing is used to determine the load at which a plastic or film will yield when sheared between two metal edges. 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.
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. 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.
Certification Formally confirming that your products and services meet all trusted external and internal standards. Due to the very large number of astk offered, descriptions of astn most commonly requested have been gathered into the following groups:.

Auditing Consulting Sourcing Training. Historical Version s – view previous versions of standard.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The shear strength is calculated by dividing the force required to qstm the specimen by the area of the sheared edge. 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 atsm strength of the material. By means of our plastic testing expertise and modular product design, we will help find the testing solution that is right for you. 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 d7332 in place.
The test is performed by clamping a test sample attached to a 1-inch punch between two metal fixtures. It is intended for use as a materials screening and materials comparison test of plastics available in the form of sheets or molded disks.
Moreover, the fact that the shear strength is calculated by dividing the load by the area of the shear strength is calculated by dividing the load by the area of the sheared edge circumference X thickness should not be interpreted as indicating that the shear strength value so obtained is solely a material property, independent of thickness. ASTM D specifies constant rate of extension aetm machine universal test machine. 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.
Therefore, it is advisable to refer to that material specification before using this test method. Other non-standard, comparative-type punch shear test methods have also been developed. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: The area of the sheared edge is equal to the circumference of the punch multiplied by the thickness of the specimen.
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.
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. 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. 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.
However, a uniform shear stress state is not attained; severe stress concentrations occur at the edges of the punch. The shear force is simply calculated as the maximum force applied divided by asm 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.

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 qstm so obtained is solely a material property, independent of thickness.
The values given in parentheses are for information only. Dd732 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. Validating the specifications, value and safety of your raw materials, products and assets.

We are confident that we have what you are looking for. As a materials screening test it does have the advantages of requiring a simple specimen and utilizing a simple test procedure. 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 astk 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. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.
ASTM Aatm testing covers the punch-type shear test and is intended for use in determining the shear strength of test specimens of organic plastics in the form of sheets and molded disks in thicknesses from 0.
The results are expressed as shear strength and are given in the units of MPa or psi.
