1. Simple Introduction
JB-500B impact testing machines are used to determine the impact toughness of metal materials under dynamic load. The pendulum of the machine can be raised or released automatically. This refers to automatic lift the arm/automatic return arm. They have the features of easy operation, high efficiency, safe and reliable. The machines are especially suitable for laboratory, metallurgy industry, machinery production, steel plant and other fields, it can meet test standards: ASTM E23, ISO148-2006 and GB/T3808-2002, GB/229-2007.
