Beskrivelse

1.1 This document
 amplifies the general principles to be observed in designing experiments for the numerical
estimation of the precision of measurement methods by means of a collaborative
interlaboratory experiment;
 provides a detailed practical description of the basic method for routine use in estimating the
precision of measurement methods;
 provides guidance to all personnel concerned with designing, performing or analysing the
results of the tests for estimating precision.
NOTE – Modifications to this basic method for particular purposes are given in other parts of ISO 5725.
Annex C provides practical examples of estimating the precision of measurement methods by
experiment.
1.2 This document is concerned exclusively with measurement methods which yield measurements on a
continuous scale and give a single value as the test result, although this single value may be the outcome
of a calculation from a set of observations.
1.3 It assumes that in the design and performance of the precision experiment, all the principles as laid
down in ISO 5725-1 have been observed. The basic method uses the same number of test results in each
laboratory, with each laboratory analysing the same levels of test sample; i.e. a balanced uniform-level
experiment. The basic method applies to procedures that have been standardized and are in regular use
in a number of laboratories.
