ASTM E23

Available in 300J, 500J, and 750J capacities

Qualitest offers Charpy / Izod Impact Testers with capacities up to 750J meeting and exceeding ASTM E23, ISO, DIN, JIS, and standard requirements. The key benefits of this line of top technology models are price competitiveness, extremely high precision, and durability, automatic motorized lifting of the pendulum hammer to optimize cycle times, flexibility, efficiency for low/high-temperature testing, and much more. Optionally we offer temperature chambers, automated sample handling, centering devices, Charpy sample preparation, and broaching machines for preparation of notched bar specimens.

Main Features:

  • The lifting of the hammer is performed by a motorized system, for automatically resetting the instrument after each test
  • Specimen loading is done via a special device that automatically centers the specimen on the supports
  • The digital console is complete with a backlight LCD display and keyboard with a tactile membrane
  • The control unit allows the selection of each test type, with the corresponding reference standard. The results can be displayed in sequence on the display and stored in the memory
  • The results can be printed or handled by dedicated software installed on a PC.
  • The knife can be equipped with instruments for dynamic analysis of the absorbed energy during the specimen impact
  • This advanced system fully meets the requirements of ASTM E-23 and EN 10045/1 standards, with outstanding quality and user-friendliness
Applications

The ability of a material to absorb energy and plastically deform without fracturing is much required in materials for better toughness used in modern industry. Amount of energy per unit volume that a material can absorb before rupturing is needed to be measured, in other words keeping a balance of strength and ductility, higher the material's resistance to fracture when stressed tougher the material. 

The Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain-rate test which determines the amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a given material's notch toughness and acts as a tool to study temperature-dependent ductile-brittle transition. It is widely applied in the industry since it is easy to prepare and conduct and results can be obtained quickly and cheaply. 

ASTM E23 and other international standards like EN 10045/1, ISO 148-1, and JIS Z 2242 prescribe a standard procedure to test the absorbed energy of Metallic Notched Bars with Instruments known as Charpy Machines.

Charpy Impact Testers conduct large quantities of metal impact tests continuously, display the impact-absorbing energy and pre-elevation rotation angle of the pendulum and print test reports. It is useful not only for manufacturers of metal materials and quality inspection organizations but also for research institutes for analysis of new materials.

Qualitest’s Quali-Impact Series of Impact Testers for Notched Bars are the advanced versions of these machines having automatic sample feeding system to greatly improve the test efficiency and reduce human errors. Temperature Controlling Chambers further facilitate this testing to perform tests at sub-zero temperatures.

Features/Advantages

Quali-Impact is an advanced Charpy Impact Tester for metals, featuring an integrated mainframe and base design, symmetric pillars, and a beam-supported pendulum shaft. It boasts high stability, excellent rigidity, a simple and reliable structure, and high precision.

The software package contains self-check programs in accordance with the latest ASTM E23–05 and ISO148. Specially engineered pendulum damping system to avoid impact generated during operation of the pendulum and damage to the pendulum, effectively reduce operation noises, increase the service life of the equipment and improve operating safety.

Standard double-stage reducer replaced the old pendulum and complex transmission system, with the features of simple structure, easy assembly and repair, long service life and low failure rate. A fully-enclosed protective cage to effectively avoid splatter of fractured samples, prevent the operator from entering the test field during testing, and ensure the safety of the operators and the equipment.

Advanced PLC control system controls the operation of the pendulum (lift, fall and impact), and a high-precision rotary encoder is used to ensure the pendulum positions in real-time. The system has good anti-interference, reliability, stability and data accuracy. Wide measurement range, with a lower limit of 10J, greatly widening the application range. Digital display (Minimum resolution of 0.1J) to prevent energy loss from pointer friction; touch screen or computer for easy test control; automatic.
