These performance uncertainties reflect the combined effect to all the separate uncertainties indirect verification. The check involves at least one iiso being made on a hardness reference block, calibrated in accordance with ISO As a reference, an EA guideline [7] is available. It izo intended to make the annex normative in the next revision of this part of ISO Standard.

It is strongly recommended that this procedure be applied for a maximum of one year after the successful passing of a direct verification. The work of preparing International Standards is normally carried out through ISO technical committees. The main task of technical committees is to prepare International Standards. The procedure for the determination of U is explained in Table D.

The correction factors are tabulated in terms of the ratio of lso mean diagonal d of the indentation to the diameter D of the sphere. Proceed to Checkout Continue Shopping.


ISO – Metallic materials — Vickers hardness test — Part 1: Test method

In GUM, it is recommended to use a correction to compensate for such systematic effects. In 65071- case, an estimate of type A standard uncertainty may be obtained from the statistical analysis of repeated indentations into the test piece. For low-force hardness and microhardness tests, the maximum time shall not exceed 10 s.

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: The measured dimension should agree with the certified value to within the maximum permissible error given in Table 5 of ISO This is particularly true for low-force Vickers hardness tests and Vickers microhardness tests, where the principal limitation will arise in the measurement of the diagonals of the indentation.

This standard is also available to be included in Standards Subscriptions. 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 6570-1 considered.

A record of these results should be maintained over isp period of time, and used to measure reproducibility and monitor drift of the machine. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.

Independent of the type of sources, for hardness there are two possibilities for the determination of the uncertainty.

Because of this approach, it is important that the individual machine components are operating within the tolerances.
