Main characteristics TS, UYS, YS(offset0,2), E5D, ELu, E
Other characteristics LYS, YS(EUL0,5), YPE
  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: Results are numerical. For each characteristic selected by the participant, 1 result shall be provided for each sample. The statistical computation will provide an assigned value with its attached uncertainty, values of standard deviations for repeatability, for reproductibility, limits of alerts for bias and repeatability of the participant, indiviual values for uncertainty of results of participants.
Number of samples per participant: 6
Product submitted to tests: Non alloyed steel
Type of samples: Bars
Approximate dimensions of samples: Ø20x300 mm
Specific preparation to be performed by the participant:  Machining of test specimens
                   
Special notice for this ILC: LYS, UYS and YPE may be not determinable, according to the type of steel.
