ASTM D732 TESTING FIXTURE
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:.
Certification Formally confirming that your products and services meet all trusted external and internal standards. Specimen thicknesses can range from 0. 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 the measured shear strength.
Validating the specifications, value and safety of your asmt materials, products and assets.
Shear Strength Test by ASTM D732
As a materials screening test it does have the advantages of requiring a simple specimen and utilizing a simple test procedure. By means of our plastic testing expertise and modular product design, we will help find the testing solution that is right for you. 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.
It is intended for use as a materials screening and materials comparison test of plastics available in the form of sheets or molded disks. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. A universal testing machine is used to push the punch until shearing of the specimen occurs. The area of the sheared edge is equal to the circumference of the punch multiplied by the thickness of the specimen.

Shear Strength Test by ASTM D
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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Touchstone Research Laboratory, Ltd.
Give one of our application engineers a call today for help with creating the best 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. Send us a request Wilton UK: 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.
The shear force is simply calculated as the maximum force applied divided by the shear area punch circumference x specimen thickness.
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.
Therefore, it is advisable to refer to that material specification before using this test method. Need help or have a question? The lower end of qstm 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.
