ME24SS Participation to ILC Determination of the grain size and of the content of non metallic inclusions of an austenitic steel


Reference of the ILC ME24SS
References of test methods ISO 643  ASTM E112  ISO 4967  ASTM E45 Methods A, D, E  EN 10247
Frequency Each year
Main characteristics G (Grain size), Rating of A, B, C, D, DS inclusions according to ISO 4967 method A and/or B and/or ASTM E45 method A and/or D and/or B - Ratings P, M, K according to EN 10247.
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 Austenitic stainless steel: 3 - Grain size: 30
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 For this ILC, a series of samples and a series of images are provided for evaluation.
Type of samples Bars - Document
Approximate dimensions of samples Bars: Ø40x20 mm - Document: 1x1 mm
Specific preparation to be performed by the participant  Bars: Preparation of surfaces of observation - Document: 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 Results obtained by several methods may be provided (if the methods are not destructive)
