scope:

The purpose of this part of ISO 5725 is to give some indications of the way in which accuracy data can be used in various practical situations by:

a) giving a standard method of calculating the repeatability limit, the reproducibility limit and other limits to be used in examining the test results obtained by a standard measurement method;

b) providing a way of checking the acceptability of test results obtained under repeatability or reproducibility conditions;

c) describing how to assess the stability of results within a laboratory over a period of time, and thus providing a method of "quality control" of the operations within that laboratory;

d) describing how to assess whether a given labora tory is able to use a given standard measurement method in a satisfactory way;

e) describing how to compare alternative measurement methods.

This part of ISO 5725 is concerned exclusively with measurement methods which yield measurements on a continuous scale and give a single numerical figure as the result, although this single figure may be the outcome of a calculation from a set of observations.

It is assumed that the estimates of trueness and precision for the method have been obtained in accordance with parts 1 to 5 of ISO 5725.

Any additional information regarding the field of application will be given at the beginning of each particular application.
