Alternate Punch Shear Fixture Configurations. 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.

The area of the sheared edge is equal to ast, circumference of the astn multiplied by the thickness of the specimen. 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.

Enabling you to aatm and mitigate the intrinsic risk in your operations, supply chains and business processes. Shear strength testing is used to determine the load at which a plastic or s732 will yield when sheared between two metal edges.

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. Sources of Additional Information: There is no known ISO equivalent to this standard. A universal testing machine is used to push the punch until shearing of the specimen occurs.

ASTM D – Shear Punch Fixture

Assurance Testing Inspection Certification. 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part aastm the standard.

The results are expressed as shear strength and are given in the units of MPa or psi. Related Polymer Shear Test Services: The test is performed by clamping a test sample attached to a 1-inch punch between two metal fixtures.

ASTM D732 Shear Punch Test Equipment for Plastics

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. Select from list below: 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 specimen is clamped between the two hardened steel disks of the punch shown at the lower right of the photograph. Figure 2 shows two such fixtures. ASTM D specifies constant rate of extension testing machine universal test machine. 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.

Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Touchstone Research Laboratory, Ltd.

Link to Active This link will always route to the current Active version of the standard. 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. ASTM D test procedure: Inspection Validating the specifications, value and safety of your raw materials, products and assets.

Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: 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.

Auditing Consulting Sourcing Training. It is intended for use as a materials screening and materials comparison test of plastics available in the form of sheets or molded disks. Other non-standard, comparative-type punch shear test methods have also been developed. The shear strength is calculated by dividing the force required to shear the specimen by the area of the sheared edge.

ASTM D TESTING FIXTURE

A male punch is then forced through the hole in the metal fixture causing shear along the edge of the hole. Specimen thicknesses can range from 0. Need help or have a question? Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D The shear force is simply calculated as the maximum astmm applied divided by the shear area punch circumference x specimen thickness.

Moreover, the fact that the shear strength is calculated d73 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, aetm of thickness.

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. The values given in parentheses are for information only.

The specimens are usually 2 d7332 diameter discs or 2 inch squared plates and thickness ranging between 0. Validating the specifications, value and safety of your raw materials, products and assets. Send us a request Need help or have a question?

This test method is intended as a comparative test, and not as a quantitative measure of the shear strength of the material.
