Description

The Class D Metals Impact Tester is a dual column impact testing system designed for Charpy Impact testing according to ASTM E23, ISO 148 and EN10045 industry standards. The Class D has a peak capacity of 750J with optional pendulums for 150J, 300J, 450J and 600J. Class D comes standard as a fully enclosed system with the options of adding either a fully automatic specimen feeding system or an automatic cooling cycle. This system comes standard with an analog and digital readout for higher accuracy along with the option to add the ability to connectthe system to a computer for use with our analysis software. NextGen's Class D is a more durable solution for your high energy pendulum impact requirements allowing further upgrades to be added in the future.

Main Features

  • The heavy cast iron base is mechanically designed to avoid any vibrations having an effect on impact testing results.
  • Dual column impact frame (front and rear) provide additional structure and support for high energy testing.
  • Standard touch screen display and optional connectivity to a PC for software analysis
  • Motor-driven raising of the hammer with auto-return after completion of a test
  • Electromagnet locks the pendulum securely
  • Fully enclosed testing area for the highest safety while undergoing impact testing
  • The pendulum height and weight are precisely designed to ensure high accuracy
  • Simple and easy design to exchange the striking knife to meet ISO or ASTM standards
  • Designed with a high precision bearing for the most accurate impact results
  • Pendulum designed with rounded edges for better wind resistance to reduce any outside factors
  • Quality PLC controller for precision pendulum testing
  • Optional computer with software control is available for a semi-automatic operation. The operator must only change the specimens while the rest is controlled by the PC.
  • Optional specimen feeding system is available. Combined with the computer and software, this allows for fully automatic operation.
  • Optional cooling system is available to satisfy cold specimen testing down to -180°C

Specimen Collection and Filtering Device

Class D
  • Motorized device is used for the collection of broken specimens after undergoing an impact test. Instead of having to manual clean the tester after a test, the collection system will clear the way to avoid the striker becoming stuck.
  • Unique specimen filtering function: automatically judge qualified and unqualified specimens to different collection bins
