Pendulum Impact Tester
Category：Universal Strength Tester
Introduction
The Pendulum Impact Tester is a product developed strictly according to the national standard GB/T3808-2002 “Inspection of Pendulum Impact Testing Machines”. It performs impact tests on metallic materials according to the national standard GB/T229-1994 “Metallic Materials Charpy Impact Test Method” and undergoes factory inspection according to JJG145-82 “Pendulum Impact Testing Machine”. The sample cross-section used is 10*10MM. It is mainly used for testing ferrous metals with high impact toughness, especially steel and its alloys.
The testing principle of this product is based on the difference between the potential energy before and after the impact of the pendulum, displayed on a dial, to obtain the absorbed work of the tested sample.
Application
The Pendulum Impact Tester is widely used in testing, research and production in industries such as metrology, machinery manufacturing, metallurgy, pressure vessels, and universities.

Features
The operation is semi-automatic, which is simple to operate and highly efficient. It can automatically swing by utilizing the residual energy after the pendulum breaks the sample. Its superiority is even more evident when continuously conducting impact tests on samples.
Quality Assurance
The equipment is covered by a one-year warranty from the date of formal delivery. During the warranty period, the supplier will provide timely and free repair services for any equipment malfunctions. For any damage to parts not caused by human error, the supplier will promptly replace them free of charge. Outside the warranty period, if the equipment malfunctions during use, the supplier will promptly provide on-site service and actively assist the ordering party in completing the repair tasks.
FAQ
1. What is the Pendulum Impact Tester used for?
It is used to determine the impact toughness (absorbed energy) of metallic materials through the Charpy impact test method, mainly for steels and ferrous alloys.
2. What standards does the machine comply with?
It is manufactured and inspected according to:
GB/T 3808-2002
GB/T 229-1994
JJG 145-82
3. What specimen size is required?
The standard specimen size is 10 × 10 × 55 mm, with a 40 mm support span.
4. What impact energy capacities are available?
The tester is equipped with two pendulums:
300 J
150 J
5. How is the impact energy measured?
The absorbed energy is calculated from the difference in potential energy before and after impact and displayed directly on the dial.
6. What industries typically use this tester?
Metallurgy
Machinery manufacturing
Pressure vessel production
Quality inspection institutions
Universities and research laboratories
7. Is the machine automatic?
The operation is semi-automatic. After breaking the specimen, the pendulum automatically swings back using residual energy, improving testing efficiency.
8. What installation requirements are needed?
It must be installed on a concrete foundation (≥150 mm thick) or a base weighing more than 880 kg, with levelness adjusted within 0.2/1000.
9. What is the impact speed?
The standard impact speed is 5.2 m/s.
10. What is the warranty period?
The equipment comes with a one-year warranty, including free repair and replacement of non-human-damaged parts during the warranty period.
