Frequency: Each year
   
Time schedule:  
Opening date of registrations Registration deadline Date of shipment of samples Start of the tests Deadline for carrying out the tests and providing the results Date of delivery of reports
15/11/2019 30/06/2020 05/09/2020 15/09/2020 31/10/2020 15/12/2020
Note: After the deadline, registrations are only accepted within the limit of availability of samples
   
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: 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: 1 (it is necessary to order as many participations as there are participating test operators)
Product submitted to tests: Non alloyed steel
Type of samples: Bars
Approximate dimensions of samples: Ø18x400 mm
Specific preparation to be performed by the participant:  Machining of test specimens (2 test pieces per supplied sample)
                   
Special notice for this ILC: LYS, UYS and YPE may be not determinable, according to the type of steel.
