1. Capacity:

150J,300J,450J,600J,750J

2. Application

Impact testing machines evaluate an object's capacity to withstand high-rate loading and it is commonly used to determine the service life of a part or material. Impact resistance can be among the most challenging qualities to measure. The capacity evaluate this property is particularly useful in assessing product liability and safety.

Charpy tests are commonly performed on metals and some kind of  plastics and polymers.

3. Standards:

ASTM E23, ISO148-2006 and GB/T3038-2002, GB/229-200,ISO 138,EN10045.

Main Technical Specifications:

The standard unit has a vibration-damping steel casting, delivering a high level of mechanical stiffness and guaranteeing reliable test results

Operation is fast and convenient with easy specimen insertion and pendulum release. This is especially vital for tests to ISO 148 and ASTM E 23 with temperature-conditioned specimens, as they must be impacted five seconds after removal from the temperature conditioning area.

Operation is further simplified by rapid changing of Charpy fixtures and pendulums, coupled with direct access for maintenance, servicing and calibration as well as easy removal of specimen remains.

EVOTEST offers access to robust software packages for all regularly used standards plus instrumented and non-instrumented tests pendulum impact testers in the CYJBW-450C range meet the requirements of EC Machinery Directive 2006/42/EC and of EN ISO 12100 and EN ISO 13849-1/2. This also means that the failure of a separate safety control element will not cause the loss of overall instrument safety.

The electronics include a high-resolution angular encoder for precise measurement of the angle of rise. An RS232 interface is provided for connection to laboratory data management systems with plug and play PC connection via a USB port.

A special mode allows temperature-conditioned wedge-impact tests to be performed in a temperature range from -45 °C to +85 °C.Operating Principle of a Pendulum Impact Tester.

The name "pendulum impact tester" is self-explanatory for the operation of the machine. A lifted mass has potential energy. This is converted to kinetic energy by the mass being exposed to a free fall. When the mass is bound to a fixed pivot (pendulum), the velocity vector is deflected. Impact loading of a material being tested is attained at the point of highest kinetic energy (equal to the minimum potential energy) of the mass. This takes the form of a "flexure test".

This pendulum impact tester is used for analyzing the break behavior of metallic materials at impact loading. An ideal standardized specim
