Air quality - Evaluation of the suitability of a measurement procedure by comparison with a required measurement uncertainty (ISO 14956:2002) EN ISO 14956:2002

Publication date:   Mar 19, 2004

Scope

This International Standard specifies, for the field of air quality measurement procedures, the:
estimation of measurement uncertainty from actual or claimed values of all important performance characteristics of a method under stationary conditions; assessment of whether or not specified values for these performance characteristics comply with the required quality of a measured value at a stated measurand value; evaluation of the applicability of the measurement method based on laboratory performance and confirmatory field test; establishment of requirements on dynamic behaviour of instruments.
This International Standard is applicable to measurement procedures whose output is a defined time average.
