The ASTM impact testing procedure, specifically the Charpy impact test, involves preparing a rectangular-shaped sample from the material being tested with a notch in the center. The relevant ASTM standard determines the sample dimensions and notch specifications. The sample is then placed in a fixture that holds it securely in place. The test apparatus consists of a pendulum that is raised to a specific height and released to strike the sample at the notch. The impact of the pendulum causes the sample to break, and a device connected to the pendulum measures the energy absorbed by the sample during the impact. The test results are used to calculate the impact strength of the material in units of joules or foot-pounds, as specified by the relevant ASTM standard. The procedure may vary depending on the material and the specific testing requirements, and there are other ASTM standards available for different types of impact testing.
Some of the most widely used ASTM standards for impact testing include:
- ASTM E23: Standard Test Methods for Notched Bar Impact Testing of Metallic Materials
- ASTM D6110: Standard Test Method for Determining the Charpy Impact Resistance of Notched Specimens of Plastics
