HD24SM : Participation to ILC Brinell, Vickers und Rockwell hardness tests of a metal (low hardness)

HD-SM

Reference of the ILC HD24SM
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 3
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.
