This standard is the first part of the "Plastics - Determination of Hardness" series, specifying a general method for determining the hardness of plastics and hard rubber using the ball indentation method. The method involves vertically pressing a steel ball indenter into the surface of the test specimen under a specific load for a specified duration (e.g., 30 seconds), and measuring the indentation depth to calculate the hardness value. This method provides objective data for material research and development, quality control, and product acceptance. Relevant testing instruments that comply with the requirements of this standard are referred to as plastic ball indentation hardness testers.
