For this ILC, there is a risk that the number of registrations is low. To ensure an enough number participants, a pre-registration procedure is put in place, as follows:


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

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

3 - If at least 8 participants confirm their intention to participate, the CIL organisation concerned is engaged.

Main characteristics

Density (ISO 1183-1, -2 & -3 ASTM D792 ASTM D1505), Ash content (ISO 3451-1 ASTM D2584 ASTM D5630), Water content (ISO 15512 methods A, B1, B2, C, D, E ASTM 6869 ISO 760 ASTM D6980)


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.
