The specification for the product may indicate limits for the differences between the lengths of the two diagonals. 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.

In general, as a result of the measurement, method 1 [Equation D. The 65507-1 thickness is given by the point of intersection of the minimum thickness scale and a line shown dotted in the example lso Figure A. As a reference, an EA guideline [7] is available. Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards.

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.


Introduction to Materials and Materials Forming Next: Every care has been taken to ensure that the file is iiso for use by ISO member bodies. 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.

The procedure for the determination of Ucorr is explained in Table D. If not, an indirect verification should be performed.

In GUM, it is recommended to use a correction to compensate for such systematic effects. ISO consists of the following io, under the general title Metallic materials — Vickers hardness test: 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.

The chain starts at the international level using international definitions of the various hardness scales to carry out international intercomparisons. Dn log in to set a read status Setting a reading intention helps you organise your reading. Such conversions, therefore, should be avoided, unless a reliable basis for conversion can be obtained by comparison tests.

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. This item appears on List: Again there may be more recent versions of the document.

For these tests, a longer duration is permitted and this duration shall be specified as part of the hardness designation see EXAMPLE in 4. Adobe is a trademark of Adobe Systems Incorporated.



Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. It makes it easy to scan through your lists and keep track of progress.

ISO shall not be held responsible for identifying any or all such patent rights. In the unlikely event that a problem relating to it is found, please inform the Central Secretariat at the address given below. This is the base of M2. For low-force hardness and microhardness tests, the maximum time shall not exceed 10 s.

It is important that the test piece lies firmly on the support so that displacement cannot occur during the test. For dated references, only the edition cited applies. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent isi.

If the measuring system fails this test, appropriate action should be taken.

The arithmetical mean of the two readings shall be taken for the calculation of the Vickers hardness. Due to the small depth of Vickers microhardness indentations, it is essential that special precautions are taken during preparation.
