This standard specifies the method for determining the indentation hardness of plastics using Rockwell hardness testers with M, L, and R scales. A higher Rockwell hardness value indicates a harder material. This test is typically performed using a multifunctional plastic hardness tester that meets standard requirements, which can automatically apply loads, record indentation depth, and calculate hardness results. However, it should be noted that for plastics with high creep and high elasticity, the loading times of the main and initial loads can significantly affect the test results.
