Main characteristics

Rating of the appearance of the cross-cut surfaces
       

Format of the test results:

For results expressed as a choice between several possibilities (categories), Gower indexes are computed from the results, which enables the calculation of assigned values, repeatability and reproducibility standard deviations, limits of alerts for bias and repeatability of the participant, indiviual values for uncertainty of results of participants.

 

 

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 results expressed as a choice between several possibilities (categories), Gower indexes are computed from the results, which enables the calculation of assigned values, repeatability and reproducibility standard deviations, limits of alerts for bias and repeatability of the participant, indiviual values for uncertainty of results of participants.
