HD25SM : Participation to ILC Brinell, Vickers und Rockwell hardness tests of a metal (low hardness)

HD-SM

Reference of the ILC

HD25SM

References of test methods

ISO 6506-1  ISO 6507-1  ISO 6508-1  ASTM E10  ASTM E92
ASTM E18  ASTM A370
       

Frequency

Each year

Main characteristics

HBW2,5/187,5 (Brinell scale) - HV5, HV10, HV30 (Vickers scales) - HRB (Rockwell scale)

Other characteristics

HBW10/3000, HBW5/750, HBW1/30 (Brinell scales) - HV20, HV50, HV100 (Vickers scales)

 

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

1

Number of samples per participation

2

Max number of operators per participation

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

Product submitted to tests

Low hardness metal

Type of samples

Parrallelepipeds

Approximate dimensions of samples

50x50x15 mm

Specific preparation to be performed by the participant

None (other than possible necessity to polish the test specimens or to adapt their dimensions to the equipment of the participant)
                   

Special notice for this ILC

Forecast hardness level 150-250 HV. Some scales may be inappropriate, according to the type of metal. Participants may provide results for several scales.
