Rockwell hardness tests of a metal (Infrequent scales)

Presentation for participants


Reference of the ILC: HD-X-SPEC
References of test methods: ISO 6508-1  ASTM E18  ASTM A370
Frequency: Each year
Main characteristics: HRD - HRE - HRF - HRK - HR15N - HR30N - HR45N - HR15T - HR30T - HR45T
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: 2
Number of samples per participation: 3
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: 0
Type of samples: Parrallelepipeds
Approximate dimensions of samples: Parrallelepipeds: 50x50x15 mm - Parrallelepipeds: Ø50x9 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: Participants may provide results for several scales.
