Independent of the type of sources, for hardness there are two possibilities for the determination of the uncertainty. The corresponding effect on the termination of the formation of an indentation can make alterations in the hardness value. 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 finish of the surface shall permit accurate determination of the diagonal length of the indentation. 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.

It is strongly recommended that this procedure be applied for a maximum of one year after the successful passing of a direct verification. The support surfaces shall be clean and free from foreign matter scale, oil, dirt, etc. Already Subscribed to this document.

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

Figure 1 — Principle of the test The Vickers hardness is proportional to the quotient obtained by dividing the test force by the sloping area of the indentation, which 607-1 assumed to be a right pyramid with a square base, iao having at the vertex the same angle as the indenter. For low-force hardness and microhardness tests, the maximum time shall not exceed 10 s.

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. This 650-1 of ISO specifies the Vickers hardness test method, for the three different ranges of test force for metallic materials including hardmetals.

We have no amendments or corrections for this standard. The specification for the product may indicate limits for the differences between the lengths of the two diagonals. HV 2,5 24,52 N may be used. NOTE 1 A strict comparison 6057-1 hardness values is only possible at identical test forces. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

65077-1 two adjacent indentations differ in size, the spacing shall be based on the mean diagonal length of the larger indentation. The chain starts at the international level using international definitions of the various hardness scales to carry out international intercomparisons. Every care has been taken to ensure that the file is suitable for io by ISO member bodies.

In M1, the error limit, that means the range in which the machine is allowed to differ from the reference standard is used to define the source uE of the uncertainty.

In general, as a result of the measurement, method 1 [Equation D. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.

The check involves at least one indentation being made on a hardness reference block, calibrated in accordance with ISO Due to the small depth of Vickers microhardness indentations, it is essential ios special precautions are taken during preparation.

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. Such conversions, therefore, should be avoided, unless 6057-1 reliable basis for conversion can be obtained by comparison tests. The required thickness is given by the point of intersection of the minimum thickness scale and a line shown dotted in the example 650-1 Figure A.

Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.

There is no correction of the hardness values with respect to the error. ISO consists of the following parts, under the general title Metallic materials — Vickers hardness test: It may not always be possible to quantify all the identified contributions to the uncertainty.

For automated measuring systems this standard should be applied accordingly. Werkstofftechnik 4pp. This standard is not included in any packages.

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