Resumen:
This International Standard is intended to provide a common reference to uncertainty estimation in air quality measurement, including measurements of ambient air, stack emission, indoor air and workplace atmospheres. It provides comprehensive guidance and specific statistical procedures for uncertainty estimation in air quality measurement, implementing the general recommendations of the Guide to the Expression of Uncertainty in Measurement (GUM) to boundary conditions met in air quality measurement. Conditions considered include measurands varying rapidly in time, hidden deviations caused by random changes of measuring conditions not corrected for, and the experimental designs used to keep random and systematic deviations under control. Experimental designs considered include calibration procedures, intralaboratory and interlaboratory comparison procedures, drift control procedures, as well as the assessment of variances caused by hidden deviations. Guidance and statistical procedures provided by this International Standard are intended to be applicable by technical experts in routine air quality measurement, as well as in development, validation and standardisation of air quality measurement methods.
