JBW-300B microcomputer-controlled pendulum impact tester for Charpy impact toughness of metallic materials under dynamic load.
Overview
The JBW-300B JBW-300B Pendulum Impact Testing Machine is used to determine the impact toughness of metallic materials under dynamic load. It evaluates the impact resistance of materials through the energy loss caused by the pendulum impact on the specimen. It is suitable for iron and steel, non-ferrous metals, machinery manufacturing, automobile manufacturing, aerospace, quality inspection institutions and scientific research laboratories. The machine adopts microcomputer control and features accurate impact energy, convenient operation, automatic data processing and complete safety protection.

FAQ
Q1: What standards does the JBW-300B Pendulum Impact Testing Machine comply with?
A1: The JBW-300B Pendulum Impact Testing Machine is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the JBW-300B Pendulum Impact Testing Machine be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
