Naturally, direct calibration and the verification of these machines should be at the highest possible accuracy. This is particularly true for low-force Vickers hardness tests and Vickers microhardness tests, where the principal limitation will arise in the measurement of the 5607-1 of the indentation.

This is the base of M2.

Test method 1 Scope This part of ISO specifies the Vickers hardness test method, for the three different ranges of test force for metallic materials see Table 1. If the measuring system fails this test, appropriate action should be taken. Please first log in with a verified email before subscribing to alerts. The required thickness is given by the point of isoo of the minimum thickness scale and a line shown dotted in the example in Figure A.

In general, as a result of the measurement, method 1 [Equation D. These performance uncertainties reflect the combined effect to all the separate uncertainties indirect verification. In the unlikely event that a problem relating to it is found, please inform the Central Secretariat at the address given below.

It may not always be possible to quantify all the identified contributions to the uncertainty. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. It is important that the test piece lies firmly on the support so that displacement cannot occur during the test.

If two adjacent indentations differ in size, the spacing shall be based on the mean diagonal length of the larger indentation. Adobe is a trademark of Adobe Systems Incorporated. If the difference is greater, this shall be stated in the test report. Isl not, an indirect verification should be performed.


The work of preparing International Standards is normally carried out through ISO technical committees. The measured dimension should agree with the certified value to within the maximum 6507–1 error given in Table 5 of ISO The time from the initial application of the force until the full test force is reached shall not be less than 2 s nor greater than 8 s.

It is strongly recommended that this procedure be applied for a maximum of one year after the successful passing of a direct verification. NOTE Other values e. It should be noted that for anisotropic materials, for example those which have been heavily cold-worked, there will be a difference between the lengths of the two diagonals of the indentation.

Already Subscribed to this document. The main task of technical committees is to prepare International Standards. Standards Subscriptions from ANSI provides isk money-saving, multi-user solution for accessing standards. 6057-1 Berliner Union Stuttgart,pp Due to the small depth of Vickers microhardness indentations, it is essential that special isp are taken during preparation. As the voice of the U. For undated references, is latest edition of the referenced document including any amendments applies.

Standards Subsctiption may be the perfect solution. For dated references, only the edition cited applies. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. In accordance with Adobe’s licensing policy, this file may be printed or viewed but shall not be edited unless the typefaces which are embedded are licensed to and installed on the computer performing the editing.

Add to Alert PDF. The distance between the centres of two adjacent indentations shall be at least three times the mean diagonal length of the indentation in the case of steel, copper and copper alloys, and at least six times the mean diagonal length in the case of light metals, lead and tin and their alloys. Details of the software products used to create this PDF file can be found in the General Info relative to the file; the PDF-creation parameters were optimized for printing.


The chain starts at the international level using international definitions of the various hardness isso to carry out international intercomparisons. The finish of the surface shall permit accurate determination of the diagonal length of the indentation. ISO shall not be held responsible for identifying any or all such patent rights. This standard is not included in any packages. In GUM, it is recommended to use a oso to compensate for such systematic effects.

The specification for the product may indicate limits for the differences between the lengths of the two diagonals.

For automated measuring systems this standard 65077-1 be applied accordingly. Ihre Klassifizierung und Auswirkung auf die Messwerte. A record of these results should be maintained over a period of time, and used to measure reproducibility and monitor drift of the machine.

Because of this approach, it is important that the individual machine components are operating within the tolerances. NOTE 1 For indentation diagonals less than 0, mm, the increase of the uncertainty has to be considered.

You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. The arithmetical mean of the two readings shall be taken for the calculation of the Vickers hardness.

HV 2,5 24,52 N may be iiso. Every care has ieo taken to ensure that the file is suitable for use by ISO member bodies. Subscription pricing is determined by: NOTE There is evidence that some materials may be sensitive to the rate of straining which causes small changes in the value of the yield strength.
