The measured dimension 650-1 agree with the certified value to within the maximum permissible error given in Table 5 of ISO The work of preparing International Standards is normally carried out through ISO technical committees. The arithmetical mean of the two readings shall be taken for 65071- calculation of the Vickers hardness.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. The error b step 10 can be expected to be a systematic effect.
For undated references, the latest edition of the referenced document including any amendments applies. NOTE There is evidence that some materials may be sensitive to the rate of straining which causes small changes in the value of the yield strength. The chain starts at the international level using international definitions of the various hardness scales to carry out international intercomparisons.

Care should be taken, if standard uncertainties of type A ido B are summarised, that the contributions are not counted twice see Clause 4 of GUM: The specification for the product may indicate limits for the differences between the lengths of the two diagonals. Subscription pricing is determined by: NOTE 1 For indentation diagonals less than 0, mm, the increase of the uncertainty has to be considered.
Already Subscribed to this document. The procedure for the determination of U is explained in Table D. If the difference is greater, this shall be stated in 650-71 test report. In the unlikely event that a problem relating to it is found, please inform the Central Secretariat at the address given below. The duration of the test force shall be jso s to 15 s, except for tests on materials whose time-dependent properties would make this an unsuitable range.
In GUM, it is recommended to use a correction to compensate for such systematic effects. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.
A uso of these results should be maintained over a period of time, and used to measure reproducibility and monitor drift of the machine. Because of this approach, it is important that the individual machine components are operating within the tolerances.
ISO consists of the following parts, under the general title Metallic materials — Vickers hardness test: 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.
It may not always be possible to quantify all the identified contributions to the uncertainty. NOTE Other values e.
For automated measuring systems this standard should be applied accordingly. ISO shall not be held responsible for identifying any or all such patent rights. No deformation shall be visible at the back of the test piece after the test. As a reference, an EA guideline  is available.

These performance uncertainties reflect the combined effect to all the separate uncertainties indirect verification. As the voice of the U.
Every care has been taken to ensure that the file is suitable for use by ISO member bodies. 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. For low-force hardness and microhardness tests, the maximum time shall not exceed 10 s.
