scope:

This part is applicable to gas analyzers used for the determination of certain constituents in gaseous mixtures. It includes the terminology, definitions, requirements for statements by manufacturers and tests that are common to all gas analyzers. Other standards in this series, for example IEC 1207-2, describe those aspects that are specific to certain types (utilizing high-temperature ceramic sensors). This part is in accordance with the general principles set out in IEC 359 and IEC 770. It is applicable to analyzers specified for permanent installation in any location (indoors or outdoors) and to such analyzers utilizing either a sample handling system or in situ measurement technique. It is applicable to the complete analyzer when supplied by one manufacturer as an integral unit, comprised of all mechanical, electrical and electronic portions. It also applies to sensors units alone and electronic units alone when supplied separately or by different manufacturers. For the purpose of this standard, any regulator for mains-supplied power or any non-mains power supply, provided with the analyzer or specified by the manufacturer, is considered part of the analyzer whether it is integral with the analyzer or housed separately.
