ISO 6603-1-2000 "Plastics, Determination of Puncture Impact Behavior of Hard Plastics, Part 1: Non-Instrumental Impact Testing" specifies the methods used to determine the Puncture Impact performance of hard plastics under non-instrumented conditions. This standard applies to specimens of all shapes, including flat plates, and covers the entire process from specimen preparation to impact testing. Test methods include the staircase method and the grouping method, which are used to assess the impact failure energy and behavior of specimens. The scope of application of ISO 6603-1 covers specimens with thicknesses between 1 mm and 4 mm, and is suitable for different types of hard plastics, such as thermal plasticity and thermosetting plastics, as well as various filling and reinforcing materials. The standard is designed to provide comparability and accuracy, providing foundational data for engineering design and quality control of plastic materials.
