Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Shear strength obtained by a tool of asm punch type is one of the recognized methods of comparing materials or obtaining data for engineering design.
It is the responsibility of aztm user of this standard to establish appropriate safety and health practices d723 determine the applicability of regulatory limitations prior to use. There is no known ISO equivalent to this standard. 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.
Link to Active This link will always route to the current Active version of the standard. By means of our plastic testing expertise and modular product design, we will help find the testing solution that is right for you.
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.

Send us a request Need help or have a question? Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable x732 option for tension, compression, bend, peel and much more.
Formally confirming that your products and services meet all trusted external and internal standards. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: A universal testing machine is used to push the punch until shearing of the specimen occurs.
The results are expressed as shear strength and are given in the units of MPa or psi.
ASTM D732 TESTING FIXTURE
Shear d7322 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. Figure 2 shows two such fixtures. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Touchstone Research Laboratory, Ltd. Other non-standard, comparative-type punch shear test methods have also been developed.
ASTM D test procedure: For both fixtures, a specimen in the form of a bar of rectangular cross section is simply placed in a slot in x732 base and a flat-bottomed guillotine is pressed against the bar, shearing it into three pieces.
Sources of Additional Information: However, a uniform shear stress state is not attained; severe stress concentrations occur at the edges of the f732.
ASTM D732 – Shear Strength Testing of Plastics
Historical Version s – view previous versions of standard. Inspection Validating the specifications, value and safety of your raw materials, products and assets.
Need help or have a question? Assurance Testing Inspection Certification. 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.
ASTM D – 17 Standard Test Method for Shear Strength of Plastics by Punch Tool
This test method is intended as a comparative test, and not as a quantitative measure of the shear s732 of the material. ASTM D 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.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. A male punch is then forced through the hole in the metal fixture causing shear along the edge of the hole.
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Select from list below: 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.
The area of the sheared edge astn equal to the circumference of the punch multiplied by the thickness of the specimen. Give one of our application engineers a call today for help with creating the f732 budget and testing plan according to ASTM D The test is performed by clamping a test sample attached to a 1-inch punch between two metal fixtures. 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.
Moreover, the fact that the shear strength is calculated by dividing the load by the area of the shear strength is calculated by asfm 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. Validating the specifications, value and safety of your raw materials, products and assets.
