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: ASTM D covers punch-type shear tests used in determining the shear strength of test d7332 of organic plastic sheets and molded disks in thicknesses from 1. However, a uniform shear stress state is not attained; severe stress concentrations occur at the edges of the punch. The specimens are usually 2 inich diameter discs or 2 inch squared plates and thickness ranging between 0.

This specimen is clamped between the two hardened aatm disks of the punch shown at the lower right of the photograph.

The shear strength is calculated by dividing the force required to shear the specimen astmm the area of the sheared edge. 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.

ASTM D732 – Shear Strength Testing of Plastics

Assurance Testing Inspection Certification. We are confident that we have what you are looking for. 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 d7332 geometries and rates of shear, which can profoundly affect the measured shear strength.

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. D73 Version s – view previous versions of standard. Therefore, it is advisable to refer to that material specification before using this test method.

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

Shear Strength Test by ASTM D

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The area of the sheared edge is equal to the circumference of the punch multiplied by the thickness of the specimen. It is intended for use as a materials screening and materials comparison test of plastics available in the form of sheets or molded disks. 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.

ASTM D732 Shear Punch Test Equipment for Plastics

As a materials screening test it does have the advantages of requiring a simple sstm and utilizing a simple test procedure.

ASTM D specifies constant rate of extension testing machine universal test machine. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.

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.

Specimen thicknesses can range from 0. Shear strength testing is used to determine the load at which a plastic or film will yield wstm sheared between two metal edges.

However, it must be recognized that for end-use application there may be many asgm not taken into account in this test method, such as stress-concentrating geometrics and rates of shear, which can profoundly affect shear strength.

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.

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.
