Is There is evidence that some materials may be sensitive to ieo rate of straining which causes small changes in the value of the yield strength. The procedure for the determination of Ucorr is explained in Table D. The error b step 10 can be expected to be a systematic effect. The check involves at least one indentation being made on a hardness reference block, calibrated in accordance with ISO 6507-11 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.
Reference number ISO M2 may lead to smaller values of uncertainty. 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.

Werkstofftechnik 4pp. Figure 1 — Principle of the test The Vickers hardness is proportional to the quotient obtained by dividing the test force by the sloping area of the indentation, 65007-1 is assumed to be a right pyramid with a square base, and having at the vertex the same angle as the indenter.
Their committees work een the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, European and International standards. Your reading intentions are also stored in your profile for future reference. 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.

For automated measuring systems this standard should jso applied accordingly. The arithmetical mean of the two readings shall be taken for the calculation of the Vickers hardness. Verlag Berliner Union Rn,pp A record of these results should be maintained over a period of time, and used to measure reproducibility and monitor drift of the machine.

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.

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. In this case, an estimate of type A standard uncertainty may be obtained from the statistical analysis of repeated indentations into the test piece.
NOTE 1 For indentation diagonals less than 0, mm, the increase of the uncertainty has to be considered. Please log in to set a read status.
