Introduction

GB/T 39693 "Determination of the hardness of vulcanized rubber or thermoplastic rubber" aims to establish a method for determining the hardness of vulcanized rubber or thermoplastic rubber. The test method is planned to consist of nine parts. ---Part 1.Introduction and Guide. The purpose is to introduce all aspects of the hardness measurement of vulcanized rubber or thermoplastic rubber and define the hardness The terms and definitions involved in the test provide a guide for the reasonable choice of hardness test methods. ---Part 2.International Rubber Hardness (10IRHD~100IRHD). The purpose is to specify the vulcanized rubber or thermoplastic rubber country International rubber hardness (IRHD) measurement method. ---Part 3.Use the ultra-low rubber hardness (VLRH) scale to determine the hardness of the test force. The purpose is to specify vulcanized rubber or thermal Ultra-low rubber hardness (VLRH) scale for plastic rubber is a method for determining the hardness of a given test force. ---Part 4.Determine the indentation hardness by the Shore hardness tester method (Shore hardness). The purpose is to specify vulcanized rubber or thermoplastic rubber The method of measuring the indentation hardness of rubber by the Shore hardness tester (Shore hardness). ---Part 5.Use the portable international rubber hardness tester to determine the indentation hardness. The purpose is to specify vulcanized rubber or thermoplastic rubber The method for measuring the indentation hardness of the rubber by the portable international rubber hardness tester. ---Part 6.IRHD method to determine the apparent hardness of rubber rollers. The purpose is to specify IRHD for vulcanized rubber or thermoplastic rubber Method to determine the apparent hardness of rubber rollers. --- Part 7.Use the Shore hardness tester to determine the apparent hardness of the rubber roller. The purpose is to specify the use of vulcanized rubber or thermoplastic rubber The method of measuring the apparent hardness of rubber rollers by the Shore hardness tester method. ---Part 8.Using Zhao's (P Zhao's (P ---Part 9.Calibration and verification of the hardness tester. The purpose is to establish calibration and verification procedures for various rubber hardness testers.
