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. To get a fuller understanding of how the material under test reacts to impacts we suggest fully instrumenting the test with our DAS (Data Acquisition System), Visual Impact software and instrumented pendulum hammers.
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.
