Both plastic suppliers and their customers may use test results to verify product performance. The specimen is clamped onto the testing platform. By continuing to use our site, you accept our cookie policy. This sophisticated impact test provides full force and energy curves during the mili-seconds of the impact, using a “Tup” which incorporates an impact head and a load cell.

Its versatility allows it and its astk to be used in everything from car parts to doll parts; from drink bottles to the refrigerators they are stored in. ASTM D states that the specimen atsm be centered and clamped between the two plates of the support fixture in such a way as to provide uniform clamping pressure to prevent slippage during testing. Generally 4″ x 4″ plaques or 4″ diameter disks, although actual parts may also be tested.

A standard solution for conditioning is a thermostatic chamber that uses liquid nitrogen to cool the specimen to the required temperature. Sstm load-deflection curve is produced.

This test method further provides a measure of the rate sensitivity of the material to impact. Quick impact at low temperature. Environmental chamber use allows both parties to get an understanding astmm how the material may perform in colder or warmer applications. Today, the use of liquid nitrogen inside laboratories is becoming a safety issue due to the low temperature, especially in its gaseous return phase. Contattaci Request an Accessory Catalog. Link to Active This link will always route to the current Active version of the standard.

The data is often used to specify appropriate materials for applications involving impact. Once the chamber returns to equilibrium the crosshead is released to impact the specimen.

The specimens are quickly removed, one at a time, from the freezer, clamped onto the testing platform, and the crosshead is released to impact the specimen. This sophisticated impact test provides full force and energy curves during the mili-seconds of the impact, using a “Tup” which incorporates an impact head and a load cell. Due to some of the new structural uses d363 these materials, it is essential to know how they will behave when subjected to dynamic conditions — i.

Generally 4″ x 4″ plaques or 4″ diameter disks, although actual parts may also be tested.

Any size or shape that will fit into the impact tester. 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.

Since many materials especially thermoplastics exhibit lower impact strength at reduced temperatures, it is sometimes appropriate to test materials at temperatures that simulate the intended end use environment.

Dynamic failures of materials are different than those found when testing at slower, steadier speeds. Please confirm that you agree with our privacy and cookies policy to submit this form.

ISO 6603 – ASTM D3763: Quick impact at low temperature

Commonly, plastics are tested at low temperatures by conditioning the specimen immediately before the impact. The test is also used to evaluate the axtm of secondary finishing operations or other environmental factors on plastic impact properties. This is especially true of plastics where many variables can affect the material.

Since many materials especially thermoplastics exhibit lower impact strength at reduced temperatures, it is sometimes appropriate to test materials at temperatures that simulate the intended end use environment.

Impact velocity was set at 4. Since speed can be varied, it can simulate actual impact values at high-speeds. This provides better control and consistency of test results at non ambient temperatures.
