Products for Impact Testing
Impact Tests on Plastics and Metals—with ZwickRoell Your Tests are in Compliance with the Standards!
Impact tests are short-term tests, which provide information on the failure behavior of materials or components subjected to rapid loads and at varying temperatures. All materials are used on a daily basis with fluctuating temperatures. Since the fracture behavior also depends on the temperature, materials are often tested in the entire operating temperature range, indicating at which temperature and to what extent a material becomes brittle.
Instruments for Impact Testing: Pendulums and Drop weight Testers
Impact testing has become firmly established in materials and components testing. The properties determined are part of basic material characterization. ZwickRoell has been delivering quality impact testing systems for years. Our product line includes pendulum impact testers for metals and plastics, drop weight testers with an energy range of only a few joules to 100,000 joules, as well as high-speed testing machines.
- The energy range spans from 5.5 joules (pendulum impact testers) to 100,000 joules (drop weight testers).
- Our impact testers are also available in instrumented versions.
- For temperature conditioning of specimens ZwickRoell offers a temperature conditioning box and magazine. Reliable test results start with precise specimen preparation, and ZwickRoell offers solutions for standard-compliant testing.
- For particularly economical and reliable testing, ZwickRoell offers a variety of automated solutions for impact testing.

Impact tests on metals
For impact tests on metals ASTM E23 permits a velocity which can also be complied with using the HIT50P. Special accessories are required for this.
