CCQM-K133
MEASURAND Mass fraction of Benzyl Butyl Phthalate (BBP) in low concentration PVC sample (LCPVC)
NOMINAL VALUE 30 mg/kg to 200 mg/kg
The key comparison reference value xR and its associated standard uncertainty uR are computed using the Hierarchical Bayesian procedure implemented in the NIST Consensus Builder (NICOB) from the reported results, INMETRO excluded (see page 12 of the CCQM-K133 Final report).
xR = 97.0 mg/kg uR = 2.2 mg/kg
The degree of equivalence of laboratory i relative to the key comparison reference value xR is given by a pair of terms, both expressed in mg/kg:
For all participants except INMETRO, the degrees of equivalence, Di , and their expanded uncertainties, Ui , at a 95% level of confidence, were estimated along with the key comparison reference value using a Monte Carlo method in conjunction with the NICOB Hierarchical Bayes procedure.
For INMETRO, Di = (xi - xR) (see page 15 of the CCQM-K133 Final report).
