ASTM D6110 Determination of Charpy Impact Properties
ASTM D6110 defines the method used to determine the resistance of plastic to breakage when impacted in a three point bend configuration, using a pendulum system with an appropriately sized hammer arm. The test is typically uninstrumented and is used to determine the energy required to break the specimen. 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 (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 understanding of how the material will react to impact when exposed to sub-ambient temperatures we also recommend the inclusion of our Cryobox. Additionally, the application of an instrumented hammer in conjunction with our Data Acquisition System can help to identify and investigate failure modes and impact history.
For specimen preparation we suggest the use of either our Motorized Notchvis or Automatic notcher, which together with the correct knife will allow the user to notch their samples correctly, according to the test standard.
To fully understand the test set-up, procedure, results and specimen preparation requirements, please refer to the standard.
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.

The new CEAST DAS 64K is a state-of-the-art Data Acquisition System designed for impact testing instruments. Compatible with the full range of CEAST impact testing systems, including pendulum type machines (CEAST 9000 Series) and drop towers (CEAST 9300 Series), it’s the key for instrumented impact testing. The DAS 64K also enables the data collection from instrumented tups or hammers on older models and non-CEAST impact machines.
