The work of preparing International Standards is normally carried out through isO technical committees. Each member body interested in a subject for which a technical committee has been InternationalElectrotechnicalCommission(lEC)onallmattersofelectrotechnicalstandardization. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2. adopted by the technical committees are circulated to the member bodies for voting.

This International Standard specifies definitions and methods to determine performance characteristics of conditions that can be adjusted and maintained in laboratory.This is also done under field conditions for a few performance characteristics for which field testing provide relevant additional information. ISo 2006-All rights reserved V ISO 9169:2006(E) INTERNATIONALSTANDARD Air quality Definition and determination of performance characteristics of an automatic measuring system Scope This International Standard provides definitions and specifies methods to determine performance 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 p
