Projekta Nr.ISO 11222:2002
Nosaukums<p>ISO 11222:2002 provides a method for the quantification of the uncertainty of a time average of a set of air quality data obtained at a specified location over a defined averaging time period. The method is applicable to air quality data obtained by continuous or intermittent monitoring by means of a specified measuring system. The uncertainty of the time average depends on both the uncertainty of the measurement results and the uncertainty due to incomplete time coverage of the data set. </p> <p>ISO 11222:2002 is only applicable if </p> <ul><li>the set of air quality data used to calculate the time average is representative of the temporal structure of the measurand over the defined time period, </li><li>appropriate information on the uncertainty of the measurement results is available, and</li><li>the measurement results have all been obtained at the same location. </li></ul> <p>ISO 11222:2002 implements recommendations of the Guide to the Expression of Uncertainty in Measurement (GUM). </p>
