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).

Class J is widely used for lzod and Charpy impact test on softer metals, plastics and rubber specimens. Equipped with tensile impact pendulum and fixtures, it can carry on tests on plastic film and sheet. The newly enhanced design offers the most cost-effective configuration to address Charpy test from 1J to 50J, and lzod test from 1J to 22J.
NextGen's Class D – Dual Column Charpy Impact Testing system provides a high level of rigidity and specimen testing capacity. This Charpy Impact tester has a minimum capacity of 150J and a maximum capacity of 750J. The system comes standard with a digital display with software upgrade function for data plotting. The Class D impact system can also include automatic specimen feeding, cooling and heating systems as optional upgrades.
NextGen's Class G – Servo-Motor Single Column Charpy and Izod Impact Testing system is commonly used in R&D laboratories. The system offers the ultimate versatility of testing 150J, 300J or 450J capacities based on both Charpy and Izod test methods. The unit comes standard equipped with a servo motor and is designed to test at any preset angle. Additionally, this impact tester includes automatic braking of the pendulum. The standard analogue display can be upgraded to a touch screen interface. The Class G impact system can also include automatic specimen feeding, cooling and heating systems as optional upgrades.
NextGen offers an economical solution for Specimen notching and broaching for Charpy and Izod specimens. This certified system complies with ASTM ISO148, EN10045, ASTM E23, DIN 50115 standards. This automated, motorized solution is capable of preparing two specimens at any one given time up to 46 HRC. A variety of broaches are available for different geometries of notches.
