Pendulum Impact Testing Machine
Charpy, Izod, and Tensile Impact Testing
Charpy, Izod, and tensile pendulum impact tests are the most common methods for determining a material's impact strength. Understanding a material's energy absorption properties is critical — it predicts the level of plastic deformation the material can withstand before failure. While Izod and Charpy testing measure similar properties, crack propagation differs between the two due to differences in specimen design and testing configuration.

Efficient Testing
- Ergonomic Hammer and Specimen Support Setup - The ergonomic setup of the hammers and specimen supports lets users work safely and efficiently.
- Fast Energy and Configuration Changes - Switching between high (50 J) and low (0.5 J) energy hammers, and between Charpy and Izod configurations, is quick and straightforward.
- Integrated Control Panel -The integrated touch panel PC puts testing control at your fingertips, with an extensive set of test parameters stored for prompt use to maximize lab efficiency.
- Double Braking Mechanism - The manual pendulum's hammer disk brake delivers high torque with low operator effort, with a double braking surface positioned for smooth, convenient operation.
Advanced Performances
- Tester Display - The touch panel PC displays critical information, such as percentage of absorbed energy, ensuring each test runs according to the applicable testing standard.
- Patented Hammer Design - The one-piece patented hammer structure is specifically designed to reduce energy lost to vibration, delivering exceptional rigidity and superior accuracy.
- Advanced Software - Optional software adds value to results and enables post-test data export — from professional reports with graphs and tables to customized text files.
- Thermal Conditioning Chamber - The optional thermal conditioning chamber encloses the specimen vice, ensuring fast time-to-impact when testing at low temperatures.
Stiff Frame for Better Reliability
- Reduced Manual Errors - Advanced electronics automatically recognize the mounted hammer and retrieve its relevant data from the internal database, eliminating the risk of manual data entry errors.
- Accurate Energy Values - Accurate energy values require a robust, monolithic frame structure paired with a precise, non-contacting magnetic encoder that ensures zero friction — both of which the Instron 9050 is built around.
- Enhanced User Protection - Safety guards prevent unwanted access to the test area, ensuring maximum operator protection.
- Safe, Wire-Free Hammer Setup - All instrumented hammers are wire-free, eliminating downtime from hammer connection setup and the risk of wire damage.
Accessories and Options
A range of interchangeable hammers covering the full 0.5–50 J energy range, automatically recognized by the system's electronics for fast, error-free configuration changes.
Ergonomically designed specimen supports and vices for secure, repeatable specimen positioning across Charpy, Izod, and tensile configurations.
Optional advanced software for post-test data export, professional reporting, and customized data output.
Punching machines create specimens using interchangeable steel dies with hand-finished cutting edges, supporting specimen preparation to ISO 179, ISO 180, ASTM D256, ASTM D638, and other major standards.
Low-Temperature Impact Testing Supports impact testing at reduced temperatures when paired with the optional thermal conditioning chamber.
Firmly fixes the pendulum for maximum stability, minimizing vibration for reliable results — especially useful with high-energy hammers (25–50 J). Includes drawers for collecting broken specimens and storing tools and documents.
