Accuracy (trueness and precision) of measurement methods and results -- Part 2: Basic method for the determination of repeatability and reproducibility of a standard measurement method
<p><b>1.1</b> This document</p> <p>— amplifies the general principles for designing experiments for the numerical estimation of the precision of measurement methods by means of a collaborative interlaboratory experiment;</p> <p>— provides a detailed practical description of the basic method for routine use in estimating the precision of measurement methods;</p> <p>— provides guidance to all personnel concerned with designing, performing or analysing the results of the tests for estimating precision.</p> <p>NOTE Modifications to this basic method for particular purposes are given in other parts of ISO 5725.</p> <p><b>1.2 </b>It 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 can be the outcome of a calculation from a set of observations.</p> <p><b>1.3 </b>It assumes that in the design and performance of the precision experiment, all the principles as laid down in ISO 5725-1 are observed. The basic method uses the same number of test results in each
