Pre-registration to CA-X-CI Chemical analysis of cast iron


Reference of the ILC


References of test methods

All methods can be used



For this ILC, there is a risk that the number of registrations will be low. To ensure a sufficient number of participants, a pre-registration procedure is therefore set up, as follows

1 - Participants interested in participating pre-register using the registration form. No invoicing is done for this pre-registration;

2 - When at least 10 potential participants have pre-registered, CompaLab asks each of these pre-registered participants to confirm their willingness to participate and the characteristics for which they are committed to providing results;

3 - If at least 8 participants confirm their intention to participate, the organisation of the relevant ILC is initiated.

Main characteristics

C%, Si%, Mn%, S%, P%, Ni%, Cr%, Mo%, V%, Cu%, Al%, Co%, N%

Other characteristics

All other chemical elements existing in cast iron


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


Number of samples per participation


Max number of operators per participation

10 (For this CIL, 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

Cast iron

Type of samples


Approximate dimensions of samples

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
