This part of IEC 61207 applies to all aspects of analyzers using high-temperature electro-chemical sensors for the measurement of oxygen in gas.

It applies to in-situ and extractive analyzers and to analyzers installed indoors and outdoors.

The object of this part is:

  • to specify the terminology and definitions related to the functional performance of gas analyzers, utilizing a high-temperature electrochemical sensor, for the continuous measurement of oxygen concentration in a sample of gas;

  • to unify methods used in making and verifying statements on the functional performance of such analyzers;

  • to specify what tests are performed to determine the functional performance and how such tests are carried out;

  • to provide basic documents to support the application of internationally recognized quality management standards.
