Low load Vickers hardness tests

Presentation for participants

Reference of the ILC:



References of test methods:

ISO 6507-1  ISO 4545  ASTM E92  ASTM E384



Each year


Main characteristics:

HV0,1 - HV1 - HK0,1 - HK1

Other characteristics:

HV0,3 - HK0,3


Caution: The number of determinations may be low for the secundary characteristics, what may make inefficient the comparison between laboratories


Determination of the assigned values (“true values” for each characteristic):

By statistical computation of the totality of the results with possible selection on competence criteria (accreditation, validation by a reference body, quantity of tests performed in the year), test to detect possible collusion, merging of results not obtained in reproductibility conditions, suppression of technically unvalid results.


Type of statistical computation:

For numerical results, the statistical computation will provide an assigned value with its attached uncertainty, values of standard deviations for repeatability and reproductibility, limits of alerts for bias and repeatability of the participant, indiviual values for uncertainty of results of participants.

Number of products submitted to tests:


Number of samples per participation:


Max number of operators per participation:

10 (For this CIL, the type of test and sample size allow to provide results determined by several different operators)

Product submitted to tests:

Low hardness metal

Type of samples:


Approximate dimensions of samples:

25x25x15 mm

Specific preparation to be performed by the participant:

None (other than possible necessity to adapt dimensions of the test specimen to the equipment of the participant)


Special notice for this ILC:

Forecast hardness level 150-250 HV. Participants may provide results for several scales.
