NBN EN ISO 6507-1
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: This is the base of M2. Setting up reading intentions help you organise your course reading. ISO shall not be held responsible for identifying any or all such patent rights.
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.
As a reference, an EA guideline  is available. It makes it easy to scan through your lists and keep 6057-1 of progress. For these tests, a longer duration is permitted and this duration shall be specified as part of the hardness designation see EXAMPLE in 4. Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards. For automated measuring systems this standard should be applied accordingly.
Please log in to set a read status Setting a reading intention helps you organise your reading. VDI-Berichte 11pp. If not, an indirect verification should be performed.
The support surfaces shall be clean and free from foreign matter scale, oil, dirt, etc. NOTE 1 A strict comparison of hardness values is only possible at identical test forces.
ISO – Metallic materials — Vickers hardness test — Part 1: Test method
Naturally, direct calibration and the verification of these machines should be at the highest possible accuracy. Independent of the type of sources, for hardness there isp two possibilities for the determination of the uncertainty. Setting a reading intention helps you organise your reading.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. The check involves at least one indentation being made on a hardness reference block, calibrated in accordance with ISO No deformation shall be visible at the back of the test piece after the test.
These performance uncertainties reflect the combined effect to all the separate uncertainties indirect verification.
The work of preparing International Standards is normally carried out through ISO technical committees. The Red document status indicator indicates that the document 5607-1 an old version The document has likely been withdrawn by the publisher, also the meta data presented here may be out of date as it is no longer being maintained by the editorial teams at NBS.
In this case, an estimate of type A standard uncertainty may be obtained from the statistical analysis of repeated indentations into the test piece.
The correction factors are tabulated in enn of the ratio of the mean diagonal d of the indentation to the diameter D of the sphere.

Such conversions, therefore, should be avoided, unless a reliable basis for conversion can be obtained by comparison tests. The measured dimension should agree with the certified value to within the maximum permissible error given in Table 5 of ISO The procedure for the determination of Ucorr is explained in Table D.
In GUM, it is recommended to use a correction to compensate for such systematic effects. The chain starts at the international level using international definitions of the various hardness scales to carry out international intercomparisons.

Specifies the Vickers hardness test method, for the three different ranges of test force for metallic materials. 607-1 an example of what they look like: Document Status Indicators The Io document status indicator indicates that the document is: Because of this approach, it is important that the individual machine components are operating within the tolerances.
ISO consists of the following parts, under the general title Metallic materials — Vickers hardness test: M2 may lead to smaller values of uncertainty. 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.
International organizations, governmental and non-governmental, in 65071- with ISO, also take part in the work. Werkstofftechnik 4pp. The time from the initial application of the force until the full ido force is reached shall not be less than 2 s nor greater than 8 s. The specification for the product may indicate limits for the differences between the lengths of the two diagonals.
The corresponding effect on the termination of the formation of an indentation can make alterations in the hardness value.
There is no general process of accurately converting Vickers hardness into other scales of hardness or into tensile strength. NOTE 2 In general, decreasing the test iiso increases the scatter of results of the measurements.
