Air quality. Determination of the uncertainty of the time average of air quality measurements Ingestion-build-46800 you save potential costs associated1 Scope This International Standard 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
