JIS Z 8402-3:1999 English Edition

Accuracy (trueness and precision) of measurement methods and results Part 3: Intermediate measures of the precision of a standard measurement method

Abstract

This part of JIS Z 8402 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 JIS Z 8402. a) discusses the implications of the definitions of intermediate precision measures; b) presents guidance on the interpretation and application of the estimates of intermediate precision measures in practical situations; c) does not provide any measure of the errors in estimating intermediate precision measures; d) does not concern itself with determining the trueness of the measurement method itself, but does discuss the connections between trueness and measurement conditions.
