WaveMatrix 2 for Dynamic Testing. Its versatility allows it and its composites to be used in everything from car parts to doll parts; from drink bottles to the refrigerators they are stored in. Time range for data acquisition was set to 30 milliseconds.

Bluehill LE for Basic Testing. The technical content and results shall not be compared between the two test methods. Originally approved in Both plastic suppliers and their customers may use test results to verify product performance. Dynamic failures of materials are different than those found when testing at slower, steadier speeds.
WaveMatrix 2 for Dynamic Testing. Last previous edition approved in as D – Since the s, plastics have become a major industry — one that affects all aspects of our lives — providing improved packaging, creating new textiles, and permitting the production of new products and cutting-edge technologies.
ASTM does not specify a conditioning time or elapsed time from freezer to impact – typical values from other specifications are 6 hours of conditioning and 5 seconds from freezer to impact. Some of the most common are multiple peaks when testing a matrix material or multiple slope changes when testing a?
Therefore, it is advisable to refer to that material specification before using this test method. This includes, but is not limited to, strain gage force transducers, piezo-electric force transducers and accelerometers.
Since speed can be varied, it can simulate actual impact values at high-speeds, and the data is often used to specify appropriate materials for applications involving impact.
The specimens are conditioned at the specified temperature in a freezer until they reach equilibrium, generally a minimum of 6 hours. Numerous data values related to toughness and total energy are calculated including maximum force, energy at maximum force and total energy to break.
This test configuration is well suited for determining the performance characteristics of plastic materials under impact conditions.
Please confirm that you agree with our privacy and cookies policy to submit this form. The following equations are used to determine the velocity versus time: Software for Series Systems.
The technical content and results shall not be compared between the two test methods. After the specimens have been cut, randomly order specimens.
Both plastic suppliers and their customers may use test results to verify product performance. Any size or shape that will fit into the impact tester.
The crosshead, with the attached Tup, is raised to the appropriate height to provide aastm specified velocity. These recordings may have useful or important characteristics beyond those required in Section Whether your business is local or axtm, we can ensure your products meet quality, health, environmental, safety, and social accountability standards astk virtually any market around the world.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Subscribe to Our Newsletters. Speed of Testing 9. The specimen is in one piece after the penetration and the deformed material astn plastic? Environmental chamber use allows both parties to get an understanding of how the material may perform in colder or warmer applications.
WaveMatrix 2 for Dynamic Testing. With the high versatility of plastics, they atsm become the most used material in the world and require stronger standard for its mechanical and chemical properties. Impact resistance is one of the most important properties for component designers to consider, as well as the most difficult to quantify. The operator must de?

The specimens are conditioned at the specified temperature in a freezer until they reach equilibrium. This sophisticated impact test provides full force and asrm curves during the mili-seconds of the impact, using a “Tup” which incorporates an impact head and a load cell. In such systems, the curves are represented digitally as numeric arrays of load-displacement of load-time.
Care must be taken to ensure that the zero slope points are not caused by inertial effects. This test method further provides a measure of the aztm sensitivity of the material to impact. Since the s, plastics have become a major industry — one that affects all aspects of our lives — providing improved packaging, creating new textiles, and permitting the aastm of new products and cutting-edge technologies.
Email addresses must contain the symbol. In this particular case, the specimen showed a fragile break. This applies between different laboratories or between different equipment within the same laboratory.

Glossary of Materials Testing Terms. Testing per ASTM D allows both the material engineer and the design engineer to test materials for desired properties such as strength, ductility, toughness, and energy absorption.
If the source of these contributions can be veri? No other units of measurement are included in this standard. Software for Series Systems.
