Main characteristics Pass/Fail (12 samples submitted to bending at 90° and 180° with 6 different mandrels of increasing severity: 0,63t - 1t - 1,6t - 2,5t - 4t - 6,3t, 2 samples per mandrel)
Other characteristics -
   
                   
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 of yes/no type. 12 samples are submitted to tests, by sets of 2 items, with increasing severity, so that cut-off conditions for failure can be determined. The assessment of the results of participants is achieved by reference to this cut-off.
Number of samples per participant: 12
Product submitted to tests: Flat steel
Type of samples: Plates
Approximate dimensions of samples: 200x50x4-8 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: Width of samples will be adjusted to about 10 times the thickness
