ISO 5725-3-1994: Accuracy (trueness and precision) of measurement methods and results - Part 3: Intermediate measures of the precision of a standard measurement method
Specifies four intermediate 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, discusses the implications of the definitions of intermediate precision measures, presents guidance on the interpretation and application of the estimates of intermediate precision measures in practical situations, discusses the connections between trueness and measurement conditions.
