Beskrivelse

1.1 This part of ISO 5725
– specifies basic methods for estimating the bias of a measurement method and the laboratory bias
when a measurement method is applied.
– provides a practical approach of the basic method for routine use in estimating the bias of
measurement methods and laboratory bias;
– provides a brief guidance to all personnel concerned with designing, performing or analysing the
results of the measurements for estimating bias.
1.2 It is concerned exclusively with measurement methods which yield measurements on a continuous
scale and give a single value as the measurement result, although the single value may be the outcome of
a calculation from a set of observations.
1.3 In order that the measurements are made in the same way, it is important that the
measurement method has been standardized. All measurements are to be carried out according to
that measurement method.
NOTE – In ISO/IEC Guide 99:2007(VIM), “measurement procedure” (2.6) is an analogous term related to the
term “measurement method” used in this document.
1.4 When a value for the bias of a measurement method is quoted, together with a measurement result
obtained by that method, there is an implication that the same property is being measured in exactly the
same way.
