Plastics Charpy Impact Tester – Quali5J & Quali50J
Qualitest offers the Plastics Charpy Impact Tester in two highly popular models, Quali5J and Quali50J, designed for precise and reliable Charpy impact testing of thermoplastic materials. These testers conform to the ISO 179 standard, ensuring compliance with international testing requirements.

Understanding ISO 179 Standard
The ISO 179 standard specifies a method for determining the Charpy impact strength of plastics under defined conditions. It is widely used for quality control and material comparison, measuring the energy absorbed by a specimen during fracture. The test provides valuable data for evaluating a material's resistance to impact loading, which is essential for industries where durability and toughness are critical factors.
Both the Quali5J and Quali50J models come equipped with state-of-the-art touchscreen panels, providing an intuitive user interface for seamless operation. The digital display includes an automatic calibration function for energy losses, ensuring highly accurate and repeatable test results. The combination of high precision, ease of operation, and excellent repeatability has made these models best-sellers worldwide.
Model Variants & Energy Levels
- Quali5J – Ideal for lower-energy impact testing, featuring selectable energy levels of 0.5, 1, 2, 4, and 5 Joules.
