Standard Practice for Characterizing Uncertainty in Air Quality Measurements
N D7440
Annotation
This practice is for assisting developers and users of air quality methods for sampling concentrations of both airborne and settled materials in characterizing measurements as to uncertainty. Where possible, analysis into uncertainty components as recommended in the ISO Guide to the Expression of Uncertainty in Measurement (1,2 ISO GUM) is suggested. Aspects of uncertainty estimation particular to air quality measurement are emphasized. For example, air quality assessment is often complicated by: the difficulty of taking replicate measurements owing to the large spatio-temporal variation in concentration values to be measured; systematic error or bias, both corrected and uncorrected; and the (rare) non-normal distribution of errors. This practice operates mainly through example. Background and mathematical development are relegated to appendices for optional reading.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Утвержденный технологический процесс для охарактеризования неуверенности в измерениях качества воздуха
Эта практика для помощи разработчикам и пользователям методов качества воздуха для отбора концентраций и перевозимых по воздуху и зафиксированных материалов в охарактеризовании измерений относительно неуверенности. Где возможно, анализ в компоненты неуверенности, как рекомендуется в Руководстве ISO по Выражению Неуверенности в Измерении (1,2 ISO GUM) предлагается. Подчеркнуты аспекты оценки неуверенности, конкретной к измерению качества воздуха. Например, оценка качества воздуха часто осложнена: трудность взятия тиражирует измерения вследствие большого пространственно-временного изменения в значениях концентрации, которые будут измерены; систематическая ошибка или смещение, оба исправленные и неисправленные; и (редкое) ненормальное распределение ошибок. Эта практика работает в основном через пример. Фоновая и математическая разработка понижена к приложениям для дополнительного чтения.
