This is the base of M2. The arithmetical mean of the two readings shall be taken for the calculation of the Vickers hardness.

The work of preparing International Standards is normally carried out through ISO technical committees. To set a reading intention, click through to any list item, and look for the panel on the left hand side:. The correction factors are tabulated in terms of the ratio of the mean diagonal d of the indentation to the diameter D of the sphere. 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.

Unless otherwise specified, no part of this publication may be reproduced or utilized in any form or by any means, electronic or mechanical, including photocopying and microfilm, without permission in writing from either ISO at the address below or ISO’s member body in the country of the requester.

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. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.


VDI-Berichte 11pp. It is important that the test piece lies firmly on the support 65071 that displacement cannot occur during the test. For automated measuring systems this standard should be applied accordingly. These performance uncertainties reflect the combined effect to all the separate uncertainties indirect verification. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.

For dated references, only the edition cited applies. Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards. Document Status Indicators The Green document status indicator indicates that the document is: Introduction to Materials and Materials Forming Next: Details of the software products used to create this PDF file can be found in the General Info relative to the file; the Kso parameters were optimized for printing.

Figure 1 — Principle of the test The Vickers hardness is proportional to the quotient obtained by 6057-1 the test force by 66507-1 sloping area of the indentation, which is assumed to be a right pyramid with a square base, and having at the vertex the same angle as the indenter. The Red document status indicator indicates that the document is an old version The document has likely been withdrawn by the publisher, also the meta data presented here may be out of date as it is no longer being maintained by the editorial teams at NBS.

Type Document Web address https: Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Naturally, direct calibration and the verification of these machines should be at the highest possible accuracy. The corresponding effect on the termination of the formation of an indentation can make alterations in the hardness value. Setting up reading intentions help you organise your course reading.

The duration of the test force shall be 10 s to 15 s, except for tests on materials whose time-dependent properties would make this an unsuitable range. You can filter on reading intentions from the islas well as view them within your profile.


The correction factors are tabulated in terms of the ratio of the mean diagonal d of the indentation to the diameter D of the cylinder. 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 diagonals of the indentation.

It is strongly recommended that this procedure be applied for a maximum of one year after the successful passing of a direct verification.

There is no general process of accurately converting Vickers hardness into other scales of hardness or into tensile strength.

If the measuring system fails this test, appropriate action should be taken. For these tests, a longer duration is permitted and this duration shall be specified as part of the hardness designation see EXAMPLE in 4. In general, as a result of the measurement, method 1 [Equation D.
