Plastics Izod Impact Testers – Quali5.5J and Quali22J Series
Qualitest offers the Plastics Izod Impact Tester in two advanced models, Quali5.5J and Quali22J, designed for accurate and repeatable Izod impact testing of thermoplastic materials. These testers conform to ISO 180 and ASTM D256 standards, ensuring compliance with international testing requirements.

Understanding ISO 180 & ASTM D256 Standards
The ISO 180 and ASTM D256 standards define the procedures for determining the Izod impact strength of plastics under controlled conditions. These methods evaluate the amount of energy a material absorbs during fracture, providing essential data for assessing toughness and durability. These tests are widely used in quality control and material development across industries.
Model Variants & Energy Levels
- Quali5.5J – Ideal for lower-energy impact testing, featuring selectable energy levels of 1, 2.75, and 5.5 Joules.
- Quali22J – Designed for higher-energy impact testing, offering energy levels of 11 and 22 Joules.
Both models operate at a pendulum speed of 3.5 m/s, providing standardized and reliable impact measurements.
