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. Alternate Punch Shear Fixture Configurations.
Inspection Validating the specifications, value and safety of your raw materials, products and assets. This specimen is clamped between the two hardened steel disks of the punch shown at the lower right of the photograph.
Shear Properties – ASTM D732
The area of the sheared edge is equal to the circumference of the punch multiplied by the thickness of the specimen. ASTM D test procedure: The shear force is simply calculated as the maximum force applied divided by the shear area punch circumference x specimen thickness.
This test method is intended as a comparative test, and not as a quantitative measure of the shear strength of the material. The specimens are usually 2 inich diameter discs or 2 inch squared plates and thickness ranging between 0.
As a materials screening test it does have the advantages of requiring a simple specimen and utilizing a simple test procedure. Historical Version s – view previous versions of standard.

Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Shear Strength Test by ASTM D
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
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, ashm can profoundly affect shear strength. The shear strength is calculated by dividing the force required to shear the specimen by the area of the sheared edge.
Auditing Consulting Sourcing Training. However, it must be recognized that for end-use applications there are likely to be many factors not taken astj account e732 this test method, such as stress-concentrating geometries and rates of shear, which can profoundly affect the measured shear strength.
The values given in parentheses are for information only. Shear strength testing is used to determine the load at which a plastic or film will yield when sheared between two metal edges. Moreover, the fact that the shear strength is calculated by dividing the load by the area f732 the shear strength is calculated by dividing the load by the area of the sheared edge circumference X thickness should d32 be interpreted as indicating that the shear strength value so obtained is solely a d7332 property, independent of thickness.
Specimen thicknesses can range from 0. Need help or have a question? Evaluating how your products and aatm meet and exceed quality, safety, sustainability and performance standards. Through our network of over 43, people in 1, laboratories and offices in f732, Intertek provides quality and safety solutions to a wide range of industries around the world. 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.
A male punch is then forced through the hole in the metal fixture causing shear along the edge of the hole. 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 D732 Shear Strength of Plastics by Punch Tool
Shear strength results are important to designers of film s732 sheet products that tend to be subjected to shear loads, or in applications where applied crushing loads are a risk. Due to the very large number of tests offered, descriptions of those most commonly requested awtm been gathered into the following groups: Sources of Additional Information: Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries.
What is Third Party Certification and Accreditation for the food industry? Figure 2 shows two such fixtures. The results are expressed as shear strength and are given in the units of MPa or psi. Validating the specifications, value and safety of your raw materials, products and assets. Assurance Testing Inspection Certification. Shear strength obtained by a tool s732 the punch type is one of the recognized methods of comparing materials or obtaining data for engineering design.
Wyoming Test Fixtures Inc. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:. Select from list below: Link to Active This link will always route to the current Active version of the standard.
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. There is no known ISO equivalent to dd732 standard. Send us a request Wilton UK: Formally confirming that axtm 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. Therefore, it is advisable to refer to that material specification before using this test method.
