Frequency

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

Main characteristics

Infrared analysis (identification and qualitative evaluation of the 10 main absorption peaks), X (conventionnal dry material content), wcl (water soluble chloride content), Na₂O, K₂O contents

       

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.
