CA24AA : Participation to ILC Chemical analysis on aluminium alloy

CA-AA

Reference of the ILC CA24AA
References of test methods All methods can be used
Frequency Each year
Main characteristics Cu%, Mg%, Zn%, Pb%, Ni%, Ti%, Cr%, V%, Fe%, Si%, Mn%, Al%
Other characteristics All other chemical elements existing in metal
  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 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 Aluminium alloy
Type of samples Discs
Approximate dimensions of samples Ø40x10 mm
Specific preparation to be performed by the participant  Extraction of a test specimen
Special notice for this ILC All methods may be used. All chemical elements may be determined by the participating laboratory. However, a statistical computation is performed only if a sufficient quantity of results is received.
Note: Chemical analysis on metal products is covered by a large number of international standards, see http://www.iso.org/iso/home/store/catalogue_tc/catalogue_tc_browse.htm?commid=46250&published=on
