CA25CA : Participation to ILC Chemical analysis on copper alloy

CA-CA

Reference of the ILC

CA25CA

References of test methods

All methods can be used
       

Frequency

Each year

Main characteristics

Zn%, Sn%, Al%, Si%, Pb%, Ni%, Cr%, Mn%, S%, P%, Co%, As%, Cd%, Fe%, Cu%

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

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)

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
