This standard specifies the principle, symbols and instructions, hardness tester, test specimen, test method and test report of metal Vickers hardness test. This standard specifies the method of determining metal Vickers hardness according to three test force ranges. 1) Test force range, N: F ≥ 49.03, hardness symbol: ≥ HV5, test name: Vickers hardness test; 2) Test force range, N: 1.961 ≤ F < 49.03, hardness symbol: HV0.2 ~ < HV5, test name: small load Vickers hardness test; 3) Test force range, N: 0.098 07 ≤ F < 1.961, hardness symbol: HV0.01 ~ < HV0.2, test name: micro Vickers hardness test. This standard specifies that the length range of the diagonal of the Vickers hardness indentation is 0.020 ~ 1.400mm. The Vickers hardness test of special materials or products should be specified in the relevant standards.

This standard is equivalent to the international standard ISO6507-1:1997 Metallic materials Vickers hardness test Part 1, test method. Except for the more detailed provisions on the surface quality of the specimen and the test data points, the technical content is completely consistent with ISO 6507-1. This standard is formulated on the basis of the following standards: GB/T4340—1984 Metal Vickers hardness test method\. GR/T500--1985 "Metal Small Load Vickers Hardness Test Method", GB/T 4342—1991 "Metal Micro Vickers Hardness Test Method". From the date of implementation of this standard, it replaces GB/T 4340-1984 "Metal Vickers hardness test method", GB/T 5030-1985 "Metal full-load small-load Vickers hardness test method" and GB/T 4342-1991 "Gold screen micro Vickers hardness test method". Appendix A, Appendix B and Appendix C of this standard are the appendixes of the standard, and Appendix L is the appendix of the standard. This standard is carried out by the National Metallurgical Industry Bureau:
This standard is under the jurisdiction of the National Steel Standardization Technical Committee. The drafter of this standard is Zheng Iron and Steel Research President. China State Shipbuilding Corporation Lian Shipyard. The main drafters of this standard are Li Jiulin, Sang Xinbang, and Gu Jianjun. 273

ISOForeword
ISO (International Organization for Standardization) is a worldwide federation of standardization bodies (ISO member bodies). The work of preparing international standards is usually carried out by ISO technical committees. If a member body is interested in a work determined by a technical committee, it has the right to participate in the work of that committee. International organizations (official or unofficial) that maintain contact with ISO may also participate. In the field of electrical technical standardization, ISO maintains close cooperation with the International Electrical Commission (IEC). The draft international standard adopted by the ISO technical committee is submitted to the member groups for voting. It can be officially released as an international standard with the consent of at least 75 member groups that vote. The draft ISO 6507 international standard was prepared by the SC3 Hardness Test Subcommittee of Metal Mechanics Test under the ISO/TC 1G4 Committee.
[ISO6507-2:1982, ISO6507-3:1989, ISO92:1989:1989, ISO/11S2:1992:1998:1999. 409-3; 1992, amended as follows: - According to the test force range, two different international standards (IS06507-1: 1982, IS06507-21983, IS06507-3: 1989) are combined into a new draft standard: IS05507 - The three hardness test tables of IS0409-1: 1982, IS04052: 1583 and IS0409-3: 1992 are combined into Appendix C of IS07
... - The test method stipulates that the diagonal length of the indentation ranges from 0.(20 to 1,100 If the diagonal lengths of the two marks are equal, this should be noted in the test report. Added Article 8: Test result error. Added informative Appendix I: User's check on hardness tester error. IS6507 is titled Vickers hardness test for metal materials and consists of the following three parts: Part 1: Test method.
—Part 2: Calibration of hardness tester:
Part 3: Calibration of standard tester:
Appendix A, Appendix B and Appendix C are parts of TS607 standard, Appendix D is a suggestive appendix 27.1
