In the polymer industry, the application of notch cutters in accordance with ASTM and ISO standards is primarily related to fracture toughness testing and impact testing. The specific standards and methods that involve notch cutters for polymer testing include:
This standard describes the Izod impact testing method for plastics. It specifies the use of a notching tool to create a square or rectangular notch at the end of the specimen, perpendicular to the impact direction.
This standard outlines the Charpy impact testing method for plastics. It involves creating a square or rectangular notch at the center of the specimen, typically using a notching tool, to introduce a stress concentration point.
This ISO standard provides a method for determining the Charpy impact properties of plastics. It involves creating a square or rectangular notch at the center of the specimen to facilitate the impact test.
While these standards do not specifically require V-notch cutters for polymer testing, they do specify the use of notch cutters to create square or rectangular notches. These notches serve as stress concentration points, allowing for the evaluation of impact resistance and fracture toughness of polymer materials.
It's important to refer to the specific testing standards and methods for detailed instructions on the dimensions, tolerances, and notch geometries required for polymer testing using notch cutters
