This International Standard complements
ISOGuide43 (all parts) by providing detailed
descriptions of sound statistical methods for organ-
izers to use to analyse the data obtained from profi-
ciency testing schemes, and by giving recommen-
dations on their use in practice by participants in
such schemes and by accreditation bodies.
This International Standard can be applied to dem-
onstrate that the measurement results obtained by
laboratories do not exhibit evidence of an unac-
ceptable level of bias.
It is applicable to quantitative data but not to quali-
tative data.
