NF EN 23878-1993 Vickers hardness testing for cemented carbide is a French national standard for Vickers hardness testing methods for cemented carbide materials. The standard specifies the requirements for hardness testing of cemented carbide using Vickers hardness tester, including equipment specifications, specimen preparation, test procedures and methods for calculating hardness values. The standard also specifies the applicable load range, indentation measurement techniques and control of test conditions to ensure accuracy and repeability of results. In addition, the standard provides guidance on data deviation and result evaluation in cemented carbide hardness testing, which is applicable to the research and development, production quality control and performance evaluation of cemented carbide materials. This standard provides a standardized technical basis for cemented carbide hardness testing and is an important reference document in related fields.
