Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Inspection Validating s732 specifications, value and safety of your raw materials, products and assets.

Historical Version s – view previous versions of standard. 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.

ASTM-D – Grip-Engineering

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

A male punch is then forced through the hole in the metal fixture causing wstm along the edge of the hole. There is no known ISO equivalent to this standard.

The lower end of the punch is then placed in the hole in the base plate lower left and x732 cover plate top is bolted on to hold the specimen securely in place.

Alternate Punch Shear Fixture Configurations. However, a uniform shear stress state is not attained; severe stress concentrations occur at the edges of the punch.

Testing Evaluating how your x732 and services meet and exceed quality, safety, sustainability and performance standards. 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.

Figure 2 shows two such fixtures.

ASTM D732 – Shear Strength Testing of Plastics

Due to the very large number of tests offered, descriptions asm those most commonly requested have been gathered into the following groups: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The shear force is simply calculated as the maximum force applied divided by the shear area punch circumference x specimen thickness.

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. 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 zstm use. The values given in parentheses are for information only.

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. Validating the specifications, value and safety of your raw materials, products and assets.

ASTM D732 TESTING FIXTURE

This test method is intended as a comparative test, and not as a quantitative measure of the shear strength of the material. Shear strength testing is used to determine the load at which a plastic or film will yield when sheared between two metal edges. By means of our plastic testing expertise and d73 product design, we will help find the testing solution that is right for you. 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.

The test is performed by clamping a test sample attached to a e732 punch between two metal fixtures. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety atm to a wide range of industries around the world. Touchstone Research Laboratory, Ltd.

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.
