IEC 61207-3:2019 is available as IEC 61207-3:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 61207-3:2019 applies to the three main methods for measuring oxygen by its paramagnetic property, which are outlined in the introduction. It considers essential ancillary units and applies to analyzers installed indoors and outdoors. Safety-critical applications can require additional requirements from system and analyzer specifications not covered in this document. This document is intended:
- to specify terminology and definitions related to the functional performance of paramagnetic gas analyzers for the measurement of oxygen in a source 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 third edition cancels and replaces the second edition published in 2002. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) all references (normative and informative) have been updated, deleted or added to as appropriate;
b) all the terms, descriptions and definitions relating to the document have been updated where appropriate;
c) all references to “errors” have been replaced by “uncertainties” and appropriate updated definitions applied.

IEC TR 63176:2019(E) encompasses recommendations for planning, installation and operation (incl. maintenance) of process analyzer technology measuring equipment in process industry safety instrumented systems. It covers all necessary steps for the qualification of safety equipment and supplements the safety management of safety instrumented system equipment through the addition of special requirements for process analyzer technology equipment. This document does not encompass the entire safety management of safety instrumented system equipment.

IEC 60746-4:2018 applies to analyzers using membrane covered amperometric sensors. It applies to analyzers suitable for use in water containing liquids, ultrapure waters, fresh or potable water, sea water or other aqueous solutions, industrial or municipal waste water from water bodies (e.g. lakes, rivers, estuaries), as well as for industrial process streams and process liquids. Whilst in principle amperometric oxygen-analyzers are applicable in gaseous phases, the expression of performance in the gas phase is outside the scope of this document. This document is applicable to analyzers specified for permanent installation in any location (indoors or outdoors) using membrane-covered amperometric sensors. This edition includes the following significant technical changes with respect to the previous edition:

Where only one value is quoted for a performance specification, such as intrinsic uncertainty, linearity uncertainty or repeatability throughout a measurement range, this has now been defined as the maximum value, rather than an average or "representative" value. This was previously undefined. Where zero and 100 % span calibration gases are used, there is now a defined requirement that the analyser must be able to respond within its standard performance specifications beyond its normal measurement range, to allow for any under or over response of the instrument to be recorded. A new Annex A has been added giving recommended standard values of influence.

A tabulation of working potentials of this electrode pair in various solvent media is presented. A comparison of the cyclovoltametric scans for the ferricinium/ferrocene and deamethyl derivatized ferricinium/ferrocene redox couple system is presented and important features are discussed

IEC 62339-1:2006 establishes properties and physical dimensions that define the interface for surface-mount fluid distribution components with elastomeric sealing devices used within process analyser and sample-handling systems. The interface controls the dimensions and location of the sealing surfaces to allow change of just one element of the system without modification of the entire system. This is what makes the system modular from both a design and a maintenance standpoint. It cancels and replaces IEC/PAS 62339-1 published in 2003. This first edition constitutes a technical revision.
