Accuracy (trueness and precision) of measurement methods and results. Intermediate measures of the precision of a standard measurement method | Status: Superseded, Withdrawn

1 Scope 1.1 This part of ISO 5725 specifies four intermediate precision measures due to changes in observation conditions (time, calibration, operator and equipment) within a laboratory. These intermediate measures can be established by an experiment within a specific laboratory or by an interlaboratory experiment. Furthermore, this part of ISO 5725

1. a) discusses the implications of the definitions of intermediate precision measures;
2. b) presents guidance on the interpretation and application of the estimates of intermediate precision measures in practical situations;
3. c) does not provide any measure of the errors in estimating intermediate precision measures;
4. d) does not concern itself with determining the trueness of the measurement method itself, but does discuss the connections between trueness and measurement conditions.
