This is particularly true for low-force Vickers hardness tests and Vickers microhardness tests, where the principal 65507-1 will arise in the measurement of the diagonals of the indentation. For automated measuring systems this standard should be applied accordingly. Every care has been taken to ensure that the file is suitable for use by ISO member bodies. The chain starts at the international level using international definitions of the various hardness scales to carry out international intercomparisons.

A guideline for the determination is given in Annex D.

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 oso, and at least six times the mean diagonal length in the case of light metals, lead and tin and their alloys.

Supersedes BS EN Werkstofftechnik 4pp. There is no correction of the hardness values with respect to the error. Type Document Web address https: Naturally, direct calibration and the verification of these machines should be at the highest possible accuracy. For these tests, a longer 65071 is permitted and this duration shall be specified as part of the hardness designation see EXAMPLE in 4. The measured dimension should agree with the certified value to within the maximum permissible error given in Table 5 of ISO It makes it easy to scan through your lists and keep track of progress.

It may not always be possible to quantify all the identified contributions to the uncertainty. In general, as a result of the measurement, method 1 [Equation D. Here’s an example of what they look like:. 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.

If the difference is greater, this shall be stated in the test report. The arithmetical mean of the two readings shall be taken for the calculation of the Vickers hardness.

NOTE 1 For indentation diagonals less than 0, mm, the increase of the uncertainty has to be considered. For dated references, only the edition cited applies. Independent of the type of sources, for hardness there are two possibilities for the determination of the uncertainty.

Such conversions, therefore, should be avoided, unless a reliable basis for conversion can be obtained by comparison tests. Your reading intentions are private to you and will not be shown to other users.

Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards.

Because of this approach, it is important that the individual machine components are operating within the tolerances. Your reading intentions are also stored in your profile for future reference. The error b step 10 can be expected to be a systematic effect. Document Status Indicators The Green document status indicator indicates that the document is: Setting up reading intentions help you organise your course reading. No deformation shall be visible at the back of the test piece after the test.

Verlag Berliner Union Stuttgart,pp If not, an indirect verification should be performed. As a reference, an EA guideline [7] is available.

If two adjacent indentations differ in size, the spacing shall be based on the mean diagonal length of the larger indentation. The finish of the surface shall permit accurate determination of the diagonal length of the indentation. Adobe is a trademark of Adobe Systems Incorporated.

International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. The Red document status 650-1 indicates that the document is an old version The document has likely been withdrawn by the publisher, also the meta data presented here may isi out of date as it is no longer being maintained by the editorial teams at NBS.

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. What are reading intentions?

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. NOTE 2 650-71 general, decreasing the test force increases the scatter of results of the measurements.

The main task of technical committees is to prepare International Standards. In GUM, it is recommended to use a correction to compensate for such systematic effects.
