NF EN ISO 179 Charpy Impact of Plastics and Alloys Test
The NF EN ISO 179 Charpy impact test is a widely recognized method used to evaluate the notched impact strength of plastics, composites, and certain metallic alloys. This test is particularly useful for assessing the toughness of materials under dynamic loading conditions, which can help in understanding how these materials behave when subjected to sudden impacts.
The test follows the standards outlined by NF EN ISO 179-1:2014 — Plastics — Determination of notched impact strength at low temperatures. It is applicable to a variety of plastics and alloys, including polypropylene, polycarbonate, acrylonitrile butadiene styrene (ABS), and various types of steel. The test provides insights into the material's resistance to fracture under impact loading, which is critical for applications such as automotive parts, electrical components, and safety gear.
The Charpy V-Notched Impact Test involves subjecting a sample with a specific notch geometry to a sudden impact from a falling pendulum or hammer. The absorbed energy during this process is measured and used to calculate the notched impact strength (J/m). This value provides valuable information about the material's toughness, which can be crucial for ensuring reliability in high-stress environments.
The test setup typically includes a Charpy testing machine equipped with a pendulum capable of delivering precise impacts. The sample is held in place by jaws that align it perfectly with the impact path. The notch geometry is standardized to ensure consistent results across different laboratories, adhering strictly to ISO standards.
Specimen preparation for this test involves machining rectangular or cylindrical samples according to specified dimensions and tolerances. A V-notch is then machined into one end of the sample, which must meet precise geometric requirements set by NF EN ISO 179-1:2014. The notch depth, width, and angle are critical factors that can influence the test results.
The testing process itself involves a series of carefully controlled impacts on multiple samples to ensure statistical significance. After each impact, the sample is inspected for signs of fracture or damage. The absorbed energy from these impacts is recorded, and an average value is calculated based on the results obtained from all tested specimens.
The Charpy Impact Test is not only a quality assurance tool but also serves as a critical component in research and development (R&D) efforts aimed at improving material properties. By understanding how different materials respond to impact loading, engineers can optimize designs for better performance and durability. This test is particularly valuable when selecting materials for high-stress applications where the potential for sudden failure could have significant consequences.
In summary, the NF EN ISO 179 Charpy Impact Test provides essential data on material toughness that is crucial for ensuring product reliability in demanding environments. Its widespread use across industries underscores its importance as a standard method for assessing the impact resistance of plastics and alloys.
