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 side: International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

For low-force hardness and microhardness tests, the maximum time shall not exceed 10 s. The 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.

BS EN ISO 6507-1:2018

NOTE 1 For indentation diagonals less than 0, mm, the increase of the uncertainty has to be considered. It should be noted that for anisotropic materials, for oso those which have been heavily cold-worked, there will be a difference between the lengths of the two diagonals of the indentation.

The duration of the test 6507- shall be 10 s to 15 s, except for tests on materials whose time-dependent properties would make this an unsuitable range. Again there may be more recent versions of the document. Setting up reading intentions help you organise your course reading. If the measuring system fails this test, appropriate action should be taken.

This is the base of M2. Please log in to set a read status. Your reading intentions are also stored in your profile for future reference. If the difference is greater, this shall be stated in the test report. The main task of technical committees is to prepare International Standards. Werkstofftechnik 4pp. In accordance with Adobe’s licensing policy, this file may be printed or viewed but shall not be edited unless the typefaces which are embedded are licensed to and installed on the computer performing the editing.

NOTE 2 In general, decreasing the test force increases the scatter of results of the measurements. NOTE Other values e.

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. VDI-Berichte 11pp. For automated measuring systems this standard should be applied accordingly. To set a reading intention, click through to any list item, and look for the panel on the left hand side:. Setting a reading intention helps you organise your reading.

Your reading intentions are private to you and will not be shown to other users. The arithmetical mean of the two readings shall be taken for the calculation of the Vickers hardness. This item appears on List: Figure 1 — Principle of the test The Vickers hardness is proportional to the quotient obtained by dividing the test force by isi sloping area of the 6507- which is assumed to be a right pyramid with a square base, and having at the vertex the same angle as the indenter.

What are reading intentions?

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 procedure for the determination of U is explained in Table D.

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. These performance uncertainties uso the combined effect to all the separate uncertainties indirect verification. Naturally, direct calibration and the verification of these machines should be at the 6570-1 possible accuracy. The Red document status indicator indicates that the document is 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 sn NBS.

Type Document Web address https: The corresponding effect on the termination of the formation of an indentation can make alterations in the hardness value.

If two 6057-1 indentations differ in size, the spacing shall be based on the mean diagonal length of the larger indentation. Such conversions, therefore, should be avoided, unless a reliable basis for conversion can be obtained by comparison tests.

Every care has been taken to ensure that the file dn suitable for use by ISO member bodies. The 650-1 factors are tabulated in terms of the ratio of the mean diagonal d of the indentation to the diameter D of the cylinder.

In downloading this file, parties accept therein the responsibility of not infringing Adobe’s jso policy. There is no correction of the hardness values with respect to the error. Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards.

The Amber document status indicator indicates that some caution is needed when using this document – it is either: No deformation shall be visible at the back of the test piece after the test.
