ASTM D 6110 Charpy Impact Resistance of Notched Plastic Specimens per ASTM D 6110
ASTM D 6110 defines the method used to determine the resistance of plastic to breakage when impacted in a three point bend configuration. The test is an uninstrumented test that is used to characterize the impact behavior by impact strength only, using a pendulum type system with a hammer whose potential energy is approximately equal to the particular energy to break to be measure. Different test parameters are specified according to the type of material that the specimen is made of as well as the type of notch cut in it. While similar to ISO 179-1 Plastics – Determination of Charpy Impact Properties – Non-Instrumented Impact Method the defined tests are significantly different and therefore are not interchangeable.
To meet the requirements of the standard we recommend our CEAST 9050 Pendulum – in either manual or motorized version, along with a specimen support vise, properly sized shoulders, and hammers. To get a full understating of how the material will react to impact when exposed to sub-ambient temperatures we recommend the inclusion of our Cryo Dispenser.
For proper specimen preparation we suggest the use of either our Motorized Notchvis or Automatic notcher with the appropriate notching knife that meets the desired notch as defined in the test standard.
We recommend reviewing the test standard to fully understand the test set-up, procedure, results requirements as well as the specimen preparation requirements.
Impact resilience is one of the most important properties and cost-effective evaluations for material producers, both with respect to product development and quality control. As components could fail at stress levels well below the critical fracture stress, accurate determination of impact damage propagation is necessary. With the combined experience of CEAST, Instron® has more than 50 years experience in designing pendulum impact testing systems.
