Resumen:
IEC 61207-2:2019 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.
This second edition cancels and replaces the first edition published in 1994. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition.
a) all the terms and definitions relating to the document have been updated where appropriate;
b) the description of the principle of the galvanic cell has been expanded and clarified;
c) new definitions and illustrations have been added for different measurement methods for oxygen using solid electrolytes for galvanic cells;
d) new illustrations have been added for existing descriptions for ion pump cells;
e) a more detailed description of the effect of the presence of oxidizable gases has been added;
f) all references to “errors” have been replaced by “ uncertainties” and appropriate updated definitions applied.
