Introduction HUALONG CBD 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 CBD 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. CHARPY Test Procedure The CHARPY test procedure may be summarized as follows: the test specimen is thermally conditioned and positioned on the specimen supports against the anvils; the pendulum is released without vibration, and the specimen is impacted by the striker. Information is obtained from the machine and from the broken specimen. Application range ISO 148-1 -Metallic materials - CHARPY pendulum impact test. JIS Z 2242 -Method for CHARPY pendulum impact test of metallic materials. EN 10045-1 -Metallic materials-CHARPY impact test. ASTM E23 (CHARPY) -Standard test method for notched bar impact testing of metallic materials. GOST 9454-78 -Impact bending test method at low, room and high temp
