Description
The Class G Metals Impact Tester is a single column impact testing system designed for Charpy and Izod Impact testing according to ASTM E23, ASTM E1820, ASTM E2298, ISO 148 and EN10045 industry standards. This unit has the highest accuracy and can be equipped with a force transducer for precise data sampling and complete measurement system. The Class G has a peak capacity of 450J with optional pendulums for 150J and 300J. Class Gcomes standard as a fully enclosed system and allows for impact testing at any pre-set angle. This system comes standard with an analog and digital readout for higher accuracy along with the option to add the ability to connect the system to a computer for use with our analysis software. NextGen's Class Gis a universal impact tester for various applications and allows the users to comprehend the most information about your specimen when performing an impact test. Class G-4 is an instrumented type meaning there is a force transducer inside the strikerwhich enables the determination of characteristic force, energy and displacement parameters such as pre-maximum force energy (Wm), the post maximum force energy, the general yield force (Fgy), the force at brittle fracture initiation (Fbf) and the arrest force (Fa).
