For undated references, the latest edition of the referenced document including any amendments applies. NOTE 1 For indentation diagonals less than 0, mm, the increase of the uncertainty has to be considered.
This is the base of M2. Setting up reading intentions help you organise your course reading. Due to the small depth of Vickers microhardness indentations, it is essential rn special precautions are taken during preparation.
Ihre Klassifizierung und Auswirkung auf die Messwerte. Introduction to Materials and Materials Forming Next: It may not always be possible to quantify all the identified contributions to the uncertainty. Unless otherwise specified, no 6507–1 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 607-1 below or ISO’s member body in the country of the requester.
If the difference is greater, this shall be stated in the test report. Type Document Web address https: For low-force hardness and microhardness tests, the maximum time shall not exceed 10 s. The procedure for the determination of Ucorr is explained in Table D. Your reading intentions are also stored in your profile for future reference.
Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards. Your reading intentions are private to you and will not be shown to other users.
NOTE Other values e. Eh the em event that a problem relating to it is found, please inform the Central Secretariat at the address given below.
International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. 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 is assumed to be a right pyramid with a square base, and having at the vertex the same angle as the indenter.

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. If the measuring system fails this test, appropriate action should be taken.
In this case, an estimate of type A standard uncertainty may be obtained from the statistical analysis of repeated indentations into the test piece.
ISO consists of the following parts, under the general title Metallic materials — Vickers hardness test: How do I set a reading intention To set a reading intention, click through to any list item, and look for the panel on the left hand ido The finish of the surface shall permit accurate determination of the diagonal length of the indentation.
It is important that the test piece lies firmly on the support so that displacement cannot occur during the test.
The specification for the product may indicate limits for the differences between the lengths of the two diagonals. Adobe is a trademark of Adobe Systems Incorporated. Document Status Indicators The Green document status indicator indicates that the document is: Here’s an example of what they look like: Each member body interested in a subject for which a technical committee ixo been established has the right to be represented on that committee.
A guideline for the determination is given in Annex D. M2 may lead to smaller values of uncertainty. Because of this approach, it is important that the individual machine components are operating within the tolerances.
ISO – Metallic materials — Vickers hardness test — Part 1: Test method
The measured dimension should agree with the certified value to within the maximum permissible error given in Table 5 of ISO Every care has been taken to ensure that the file is suitable for use by ISO member bodies.
In general, as a result of the measurement, method 1 [Equation D. It is intended to make the annex normative in the next revision of this part of ISO Standard.
It makes it easy to scan through your lists and keep track of progress. Independent of the type of sources, for hardness there are two possibilities for the determination of the uncertainty. A record of these results should be maintained over a period of time, and used to measure reproducibility and monitor 66507-1 of the machine.

The support surfaces shall be clean and free from foreign matter scale, oil, dirt, etc. If not, an indirect verification should be performed. Please log in to set a read status Setting a reading intention helps you organise your reading. Care should be taken, if standard uncertainties of type A and B are summarised, that the contributions are not counted twice see Clause 4 of GUM: The error b step 10 can be expected to be a systematic effect.
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. The check involves at least one indentation being made on a hardness reference block, calibrated in accordance with ISO 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.
