The single-laboratory standard deviation, calculated from results generated under repeatability conditions as defined in ISO standard 5725-1^f1 (= repeatability standard deviation estimated in a single laboratory approach according to the Harmonized Guidelines for Single-Laboratory Validation of Methods of Analysis^f2).

The average within laboratory standard deviation, calculated from results generated under repeatability conditions as defined in ISO standard 5725-1 in a collaborative trial with a minimum of eight laboratories conducted according to the Protocol for the Design, Conduct and Interpretation of Method-Performance Studies^f3.

The between laboratory standard deviation, calculated from results under reproducibility conditions as defined in ISO standard 5725-1 and according to the Protocol for the Design, Conduct and Interpretation of Method-Performance Studies.

Relative single-laboratory repeatability standard deviation (S_i expressed in percent of the measured value),

Relative average repeatability standard deviation (S_r expressed in percent of the measured value),

Relative reproducibility standard deviation (S_R expressed in percent of the measured value).
