    1、Designation: D 5280 96 ( Reapproved 2007)Standard Practice forEvaluation of Performance Characteristics of Air QualityMeasurement Methods with Linear Calibration Functions1This standard is issued under the fixed designation D 5280; the number immediately following the designation indicates the year

    2、oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice2covers procedures for evaluating thefollow

    3、ing performance characteristics of air quality measure-ment methods: bias (in part only), calibration function andlinearity, instability, lower detection limit, period of unattendedoperation, selectivity, sensitivity, and upper limit of measure-ment.1.2 The procedures presented in this practice are

    4、applicableonly to air quality measurement methods with linear continu-ous calibration functions, and the output variable of which is adefined time average. The linearity may be due to postprocess-ing of the primary output variable. Additionally, replicatevalues belonging to the same input state are

    5、assumed to benormally distributed. Components required to transform theprimary measurement method output into the time averagesdesired are regarded as an integral part of this measurementmethod.1.3 For surveillance of measurement method stability underroutine measurement conditions, it may suffice t

There-fore, the procedures presented are applicable to both. Further-more, they are applicable to measurement methods for

    8、 ambi-ent, workplace, and indoor atmospheres, as well as emissions.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the ap

It is assumed that the impact ofthe influence variable on the measured value

    19、 can be fairlydetermined by tests at the extremes (see Fig. 7). Divide theinfluence variables into classes of known and unknown effecton the measured value.
