Verlag Berliner Union Stuttgart,pp In general, as a result of the measurement, method 1 [Equation D. For undated references, the latest edition of the referenced 6570-1 including any amendments applies. 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. The required thickness is given by the point of intersection of the minimum thickness scale and a line shown dotted in the example in Figure A.

6507- 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. Naturally, direct calibration and the verification of these machines should be at the highest possible accuracy. 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.

Draft International Standards adopted by the technical committees are 65007-1 to the member bodies for voting. Io procedure for the determination of U is explained in Table D. This standard is also available to be included in Standards Subscriptions.

If the measuring system fails this test, appropriate action should be taken. The Vickers hardness test is specified in this part of ISO for lengths of indentation diagonals between 0, mm and 1, mm. ISO shall not be held responsible for identifying any or all such patent rights. NOTE 2 In general, decreasing the test force increases the scatter of results of the measurements. 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.

The error b step 10 can be expected to be a systematic effect. 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.

In this case, an estimate of type A standard uncertainty may be obtained from the statistical analysis of repeated indentations into the test piece. For automated measuring systems this standard should be applied accordingly.

If not, an indirect verification should be performed.

HV 2,5 24,52 N may be used. The corresponding effect on the termination of the formation of an indentation can make alterations in the hardness value.

The error is no longer in the calculation of the uncertainty but all determined hardness values have to be corrected by b or Ucorr has to be increased by b. This is the base of M2. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Every care has been taken to ensure that the file iiso suitable for use by ISO member bodies. It is intended to make the annex normative in the next revision of this part of ISO Standard.

VDI-Berichte 11pp. This standard is not included in any packages. The procedure for the determination of Ucorr is explained in Table D. We have no amendments or corrections for this standard.

In the unlikely event that a problem relating to it is found, please inform the Iiso Secretariat at the address given below. NOTE 1 For indentation diagonals less than 0, mm, the increase of the uncertainty has to be considered. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.
