300J, 450J, 600J or 750J
The Class H Metals Impact Tester is a dual column impact testing system designed for Charpy Impact testing according to ASTM E23, ASTM E1820, ASTM E2298, ISO 148 and EN10045 industry standards. Class H is designed for high volume and especially hard materials. This unit has the highest accuracy and can be equipped with a force transducer for precise data sampling and complete measurement system. The Class H has a peak capacity of 750J with optional pendulums for 300J, 450J, 600J and 750J. Class Hcomes 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 connectthe system to a computer for use with our analysis software. Class H-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).
