What is ISO 18872: High Strain Rate Testing of Polymers about?

This paper compares the tensile properties of polymers using two different specimen geometries: the ISO527 multipurpose specimen and the ISO18872 high rate tensile specimen. It highlights the significant differences in stress-strain responses, particularly at high strain rates, and emphasizes the importance of local strain measurement for accurate material characterization. The findings indicate that while the ISO527 specimen provides a constant true strain rate, the ISO18872 specimen exhibits a non-uniform
