BS EN 61207-1:2010

What is BS EN 61207-1 - Expression of performance of gas analyzers about?  

BS EN 61207-1 is the first part of the multi-series that is applicable to the expression of the performance of gas analyzers. 

BS EN 61207-1 is a part of BS EN 61207 and is applicable to gas analyzers used for the determination of certain constituents in gaseous mixtures. 

BS EN 61207-1 specifies the terminology, definitions, requirements for statements by manufacturers, and tests that are common to all gas analyzers. Other international standards in this series, for example, IEC 61207-2, describe those aspects that are specific to certain types (utilizing high-temperature electrochemical sensors). 

BS EN 61207-1 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 an in-situ measurement technique. 

BS EN 61207-1 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 sensor units alone and electronic units alone when supplied separately or by different manufacturers. 

For the purposes of BS EN 61207-1, 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. 

Note: BS EN 61207-1 does not apply to: 

• Accessories such as recorders, analogue-to-digital converters or data acquisition systems used in conjunction with the analyzer, except that when two or more such analyzers are combined and sold as a subsystem and a single electronic unit is supplied to provide continuous measurement of several properties, that read-out unit is considered to be part of the analyzer. Similarly, e.m.f-to-current or e.m.f-to-pressure converters which are an integral part of the analyzer are included 

Who is BS EN 61207-1 - Expression of performance of gas analyzers for? 

BS EN 61207-1 on expression of performance of gas analyzers is useful for: 

• Chemical industry  
• Gas analyzers manufacturers suppliers 
• Quality control personnel   
• Analyzers 

Why should you use BS EN 61207-1 - Expression of performance of gas analyzers?  

BS EN 61207-1 includes the terminology, definitions, statements, and tests that are specific to gas analyzers, utilizing a gas analyzer, for the continuous measurement of gas or vapor concentration in a source gas BS EN 61207-1 provides you unify methods used in making and verifying statements on the functional performance of such analyzers. 

The objective of BS EN 61207-1 is: 

• To specify the general aspects in the terminology and definitions related to the performance of gas analyzers used for the continuous measurement of gas composition.
• To unify methods used in making and verifying statements on the functional performance of such analyzers. 
• To specify which tests should be performed in order to determine the functional performance and how such tests should be carried out. 
• To provide basic documents to support the application of standards of quality assurance. 

BS EN 61207-1 guides you with what tests should be performed to determine the functional performance and how such tests should be carried out. BS EN 61207-1 helps you provide basic documents to support the application of standards of quality assurance. 

What is changed since the last update?  

BS EN 61207-1:2010 supersedes EN 61207-1:1994 which is withdrawn. 

BS EN 61207-1:2010 includes some technical changes with respect to EN 61207-1:1994.  

These include: 

• All references (normative and informative) have been updated, deleted or added, as appropriate 
• All the terms and definitions relating to this International Standard have been updated 
• All references to “errors” have been replaced by “uncertainties” and appropriate updated definitions applied 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 analyzer 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
