ISO 179 is a standard published by the International Organization for Standardization (ISO). It is titled “Plastics – Determination of Charpy Impact Properties” and provides guidelines and procedures for evaluating plastic materials’ impact properties using the Charpy impact test.

The Charpy impact test is commonly used to assess plastics’ toughness and impact resistance. It involves subjecting a standardized specimen to the impact of a swinging pendulum, causing a fracture. By measuring the amount of energy absorbed during fracture, the test provides valuable insights into the material’s ability to withstand sudden impacts.

ISO 179 establishes a standardized procedure for conducting the Charpy impact test, ensuring consistency and enabling test comparison. The standard covers various aspects, including specimen preparation, test conditions, and test outcomes calculation and reporting.

By complying with ISO 179, manufacturers, researchers, and regulatory bodies can conduct reliable and consistent evaluations of plastic materials’ impact properties. This standard plays a crucial role in material selection, quality control, and ensuring plastic products’ performance and safety across various industries.
