ActivePlastics - Determination of hardness - Part 1: Ball indentation method
塑料 硬度测定 第1部分：球压痕法
Application Summary AI generated
This standard specifies the ball indentation method for determining the hardness of plastics, where a hardened steel ball is pressed into the material under a specified load to measure the indentation depth. It is applied in quality control and material testing for plastic products, such as sheets, rods, and molded parts, across industries like automotive, electronics, and consumer goods. The method is particularly used to assess the resistance of plastics to permanent deformation under compressive stress.
