ชื่อเรื่อง : Air quality — Evaluation of the suitability of a measurement procedure by comparison with a required measurement uncertainty
หมายเลขมาตรฐาน : ISO 14956:2002
ชื่อหน่วยงาน : International Organization for Standardization (ISO)
ขอบข่าย :
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.
