The HB 5367.6-1986 standard specifies the rockwell hardness (HR) test method for carbon graphite sealing materials. The standard aims to provide a unified operating specification for hardness testing of carbon graphite sealing materials, ensuring the accuracy and repeatability of test results. By using the Rockwell hardness tester, testers can evaluate the hardness of materials to judge their performance in practical applications. This method is suitable for carbon graphite sealing materials in aerospace and other industries, providing an important basis for material selection and quality control.
