Introduction
The CIT-01 Charpy and Izod Impact Tester is an advanced impact testing machine designed to measure the toughness of non-metallic materials like hard plastics, fiberglass, ceramics, cast stone, and electrical insulation materials. Combining Charpy and Izod testing capabilities in one device, it is ideal for industries such as chemical manufacturing, quality inspection, and academic research. This versatile tester adheres to international standards, including ISO 179-1 and ISO 180, ensuring accurate and reliable results.
What is Impact Testing?
Impact testing evaluates a material’s ability to withstand sudden loading or impact forces. It plays a vital role in understanding material toughness and resistance to fracture. Charpy and Izod tests are two widely used methods, each offering unique insights into material behavior.
Understanding Charpy and Izod Impact Testing
- Charpy Impact Test
The Charpy test positions the specimen horizontally, with the notch facing away from the pendulum. The pendulum strikes the center of the specimen, determining the material’s ability to absorb energy before failure. It is commonly used for metals, plastics, and composites. - Izod Impact Test
The Izod test involves a vertically positioned specimen, with the notch facing the pendulum. The upper tip of the sample is struck, measuring the energy absorbed to fracture. This test is ideal for plastics and some metals.
Key Differences
| Feature | Charpy Impact Test | Izod Impact Test |
|---|---|---|
| Materials Tested | Metals, plastics, composites | Plastics, some metals |
| Notch Types | U-notch, V-notch | V-notch only |
| Specimen Position | Horizontal | Vertical |
| Striking Point | Center | Upper tip |
| Specimen Dimensions | 55 × 10 × 10 mm | 64 × 12.7 × 3.2 mm (plastics) or 127 × 11.43 mm (metals) |
Compliance with ISO Standards
- ISO 179-1: Focuses on determining Charpy impact properties of plastics, covering test methods, specimen preparation, and energy calculations.
- ISO 180: Specifies the method for measuring Izod impact properties of plastics, detailing specimen configurations and testing procedures.
These standards provide reliable methodologies to assess material toughness and ensure results are globally comparable.
