Chemical analysis on ferrochrome

Presentation for participants

Reference of the ILC

CA24FC

References of test methods

All methods can be used

       

Frequency

This ILC can be organised this year thanks to our preregistration procedure, which ensures an enough number of participants.

Main characteristics

Cr%, Mn%, Si%, Ti%, V%, Nb%, C%, P%, S%, Al%, Cu%, Ni%

Other characteristics

All other chemical elements existing in the ferro-alloy

 

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

Grinding

                   

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
