Description
The Class D Metals Impact Tester is a Single column impact testing system designed for Charpy Impact testing according to ASTM E23, ISO 148 and EN10045 industry standards. The Class D has two popular models with peak capacities of 450J (332 ft/lbs) and 750J (553 ft/lbs) with optional pendulums for 150J (111 ft/lbs), 300J (221 ft/lbs), 450J (332 ft/lbs) and 600J (442 ft/lbs). The 450J Model is commonly used in educational institutions, government facilities, laboratories and R&D facilities. The 750J Model is most commonly used in high level industrial manufacturing facilities like steel production, heat treating facilities, aerospace and more. 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.
