HUALONG Series Pendulum Impact Testing Machine meet the growing demand for accurate and repeatable impact testing of metallic materials in accordance with ASTM and ISO specifications. They are EN 10045-2 'CHARPY impact test on metallic materials' - Method for the verification of impact testing machines and ASTM E 23, 'Standard test methods for notched bar impact testing of metallic materials'. As a general guideline, in North America, most users prefer verifications to the ASTM E 23 method while Europe generally require EN 10045-2 verifications. The system provides a rigid, integrated assembly offering maximum
mechanical performance in order to attain true pendulum impact test specimen energy for metallic materials. Incorporates a rigid, compound pendulum mounted on a reduced friction shaft assembly and a solid, vibration-free base. The pendulum is of one-piece construction, designed with a bifurcated support member and an
accurate pendulum geometry. The rigidity of the system prevents excessive elastic energy losses and reduces excessive vibration mode bending effects.
