The robotic testing system for automated impact tests in the Charpy or Izod method

The roboTest H robotic testing system can be attached to pendulum impact testers for plastics or metals.

Plastics are tested using the Charpy method to ISO 179-1 or Izod method to ISO180 / ASTM D256. The automated impact tests are performed at ambient temperature or on cooled specimens.

Metals are tested using the Charpy method to ISO 148-1 and ASTM E23 at ambient temperature.

Advantages & features

Advantages

Operator influences (hand temperature/moisture, off-center or angled specimen insertion etc.) are eliminated for high test result reproducibility
Qualified laboratory staff are relieved of routine activities, making them available for more complex tasks
Machine can be used during idle times (lunch breaks and night shifts), which utilizes the full capacity and produces faster results
Testing system reduces the testing costs per specimen and typically pays for itself within one to two years
System allows for reliable documentation and statistical long-term monitoring

Testing of plastics

The robotic testing system can be mounted to 450 joule or 750 joule pendulum impact testers.
Conventional or instrumented pendulums according to standard with a nominal energy up to 750 joules.
Specimen feeding is suitable for specimens with dimensions of 5 to 10 x 10 x 55 mm.
At a specimen height of 10 mm, the magazine can accommodate 21 specimens at ambient temperature, and at a specimen height of 5 mm it can accommodate 42 specimens.
Manual tests (for example, from a cooling bath or furnace) can be performed whenever required.

Testing of metals

The robotic testing system can be mounted to 25 joule or 50 joule pendulum impact testers.
Conventional or instrumented pendulums according to standard with nominal energy of 0.5 joules to 50 joules.
At a specimen height of 4 mm, the temperature conditioning magazine can hold 20 specimens.
Before the temperature conditioning magazine can be mounted on the robotic testing system, it and the specimens must be cooled externally to the desired temperature.
The impact test is performed within 5 seconds of removing the specimen from the temperature conditioning magazine.
Manual tests can be performed whenever required.
An industrial controller with autoEdition3 automation software controls the system.

Components and accessories for plastics testing

Specimen magazine

The specimens are in a magazine carriage, which is inserted into the temperature conditioning magazine outside of the system. The temperature conditioning magazine and the specimens are cooled to the desired temperature in an optional temperature conditioning box.

Extension for Izod tests

The robotic testing system is equipped for tests on Charpy specimens as standard. ZwickRoell offers an optional extension for tests on Izod specimens.
