Independent of the type of sources, for hardness there are two possibilities for the 65507-1 of the uncertainty. NOTE 1 For indentation diagonals less than 0, mm, the increase of the uncertainty has to be considered. 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.
ISO – Metallic materials — Vickers hardness test — Part 1: Test method
Kso 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. Verlag Berliner Union Stuttgart,pp NOTE 1 A strict comparison of hardness values is iwo possible 65007-1 identical test forces. 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.
For undated references, the latest edition of the referenced document including any amendments applies. To set a reading intention, click through to any list item, and look for the panel on the left hand side:. Specifies the Vickers hardness test method, for the three different ranges of test force for metallic materials.
Your reading intentions are private to you and will not be shown to other users. Due to the small depth of Vickers microhardness indentations, it is essential that special precautions are taken during preparation.
It is important that the test piece lies firmly on the support so that displacement cannot occur during the test. If the difference is greater, this shall be stated in the test report.
ISO consists of the following parts, under the general title Metallic materials — Vickers hardness test: Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.
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.

Introduction to Materials and Materials Forming Next: Every care has been taken to ensure that the file is suitable for use by ISO member bodies. The procedure for the determination of U is explained in Table D. Free to use BIM project management tool provides step-by-step help to define, manage and validate responsibility for information development and delivery at each stage of the asset life cycle in level 2 BIM projects.
NOTE 2 In general, decreasing the test force increases the scatter of results of the measurements.
Setting a reading intention helps you organise your reading. For these tests, a longer duration is permitted and this duration shall be specified as part of the hardness designation see Fn in 4. The chain starts at the international level using international definitions of the various hardness scales to carry out international intercomparisons.
It is strongly recommended that this procedure be applied for a maximum of one year after oso successful passing of a direct verification.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. In this case, an estimate of type A standard uncertainty may be obtained from the statistical analysis of repeated indentations into the isl piece. Want access to British Standards? 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.
The Amber document status indicator indicates that some caution is needed when using this document – it is either: What are reading intentions? Here’s an example of what they look like:. Document Status Indicators The Green document status indicator indicates that the document is: A guideline for the determination is given in Annex D.

These performance uncertainties reflect the combined effect to all the separate uncertainties indirect verification. If not, an indirect verification should be performed.
In general, as a result of the measurement, method 1 [Equation D. M2 may lead to smaller values of uncertainty. ISO shall not be held responsible for identifying any or all such patent rights.
Care should be taken, if standard uncertainties of type A and B are summarised, that the contributions fn not counted twice see Clause 4 of GUM: The measured dimension should agree with enn certified value to within the maximum permissible error given in Table 5 of ISO Because of this approach, it is important that the individual machine components are operating within the tolerances.

66507-1, direct calibration and the verification of these machines should be at the highest possible accuracy. For automated measuring systems this standard should be applied accordingly. The work of preparing International Standards is normally carried out through ISO technical committees.
