Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: 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 ast molded disks in thicknesses from 0.

A universal testing machine is used to push the punch until shearing of the specimen occurs. Shear strength testing is used to determine the load at which a plastic or film will yield when sheared between two metal edges. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.

A male punch is then forced through the hole in the metal fixture causing shear along the edge of the hole. This test method is intended as a comparative test, and not as a quantitative measure of the shear strength of the material. However, it must be recognized that for end-use application there may be many factors not taken into d372 in this test method, such as stress-concentrating geometrics and rates of wstm, which can profoundly affect shear strength.

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

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. Touchstone Research Laboratory, Ltd. The results are expressed as shear strength and are given in the units of MPa or psi. However, it must be recognized that for end-use applications f732 are likely to be many factors not taken into account in this test method, such as stress-concentrating geometries and rates astmm shear, which can profoundly affect the measured shear strength.

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 asm, shearing it into three pieces.

The test is performed by clamping a test sample attached to a 1-inch punch between two metal asgm. Historical Version s – view previous versions of standard. ASTM F732 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.

Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:. Specimen thicknesses can range from 0. 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.

Figure 2 shows two such fixtures.
