Testing per ASTM D allows both the material engineer and the design engineer to test materials for desired properties such as strength, ductility, toughness. ISO – ASTM D Quick impact at low temperature. Instron Logo. “It is our objective at Instron to provide our customers the best ownership experience by. This standard is issued under the fixed designation D ; the number immediately following fication System D lists the ASTM materials standards that.

The High Speed Impact test is used to determine toughness, load-deflection curves and total energy absorption of impact events. Link to Active This link will always route to the current Active version of the standard.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at aatm above address or at phonefaxor service astm.
Repair Services and Parts. ASTM D states that the specimen shall ast, 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. The operator must de? Concrete, Asphalt and Rock.
Another method involves performing additional tests at decreasing impact velocities. A percent drop in load from the peak is one type of criteria used.
Due to copyright restrictions, we are not able to provide copies of standards. Due to copyright restrictions, we are not able to provide copies of standards.
For d373 information, see A1. The crosshead, with the attached Tup, is raised to the appropriate height to provide the specified velocity. Tighten the clamping plate in such a way as to provide uniform clamping pressure to prevent slippage during testing. Each laboratory obtained 2 test results for each material. Glossary of Materials Testing Terms.
ASTM D3763 High-Speed Puncture Properties of Plastics
The values obtained for average maximum load and average energy to maximum load are the baseline for your control chart. A load-deflection curve is produced.
Mechanically driven systems require monitoring of the crosshead acceleration and have not been experimentally veri?
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
This is especially true of plastics where many variables can asfm the material. Dynamic failures of materials are different than those found when testing at slower, steadier speeds.

ASTM D High-Speed Puncture Properties of Plastics – Instron
It does not cover issues pertaining to the resolution, accuracy, or frequency of data acquisition. This is especially true when brittle failures are encountered.
Before testing, the thermal chamber at the base of the impact equipment is brought to temperature.
Bluehill LE for Basic Testing. Therefore, it is advisable to refer to that material specification before using this test method. It does not cover any visual interpretation or non-standard calculations not required in Zstm Work Item s – proposed revisions of this standard.
ASTM D3763 Puncture Resistance Fixture | GD3763-174
Impact velocity was set at 4. It is also valuable in composite materials where it signi? The specimens are conditioned at the specified temperature in a freezer until they reach equilibrium.
