BOS ISO 9169:2006 (IDT)

Description

This International Standard provides definitions and specifies methods to determine performance characteristics of an identified automatic air quality measuring system. Tests are carried out under stable
laboratory conditions or field conditions. The automatic measuring system is considered as a black box
operated according to specified procedures.
This International Standard applies to measuring systems for which the following information is available:
⎯ a description of the automatic measuring system providing the result of measurement in the physical unit
of the measurand;
⎯ operating procedures of the automatic measuring system including, where appropriate, the procedures of
routine adjustment, routine verification and calibration;
⎯ terms of reference for the test program specifying the client requirements and test conditions.
This International Standard applies to measuring systems for which it is possible to apply several reference
materials with accepted values with known uncertainty for the measurand, within the range of application.
This International Standard does not specify the number of automatic measuring systems to be tested.
NOTE 1 The number of automatic measuring systems is specified by the client in the terms of reference.
NOTE 2 The list of performance characteristics in this document is limited. Additional performance characteristics can
be specified by the client in the terms of reference, if appropriate.
