What is BS EN 62703 - Expression of performance of fluorometric oxygen analyzers about?
BS EN 62703 is a European standard that is applicable to the expression of the performance of fluorometric oxygen analyzers in liquid media.
BS EN 62703 is applicable to fluorometric oxygen analyzers used for the continuous determination of dissolved oxygen partial pressure or concentration. BS EN 62703 applies to fluorometric oxygen analyzers suitable for use in water-containing liquids, ultrapure waters, fresh or potable water, seawater, or other aqueous solutions, industrial or municipal wastewater from water bodies (e.g., lakes, rivers, estuaries) as well as for industrial process streams and process liquids. Whilst in principle fluorometric oxygen-analyzers are applicable in gaseous phases, the expression of performance in the gas phase will not be subject to BS EN 62703.
The sensor unit of a fluorometric oxygen analyzer being in contact with the media to be measured contains a luminophore in a polymer-membrane permeable for oxygen or within other oxygen permeable materials (or substrates).
BS EN 62703 specifies the terminology, definitions, requirements for statements by manufacturers and tests for fluorometric oxygen analyzers.
BS EN 62703 is applicable to analyzers specified for permanent installation installation in any location (indoors or outdoors) utilizing an on-line measurement technique.
The object of IEC 62703 is:
- To specify the general aspects in the terminology and definitions related to the performance of fluorometric oxygen analyzers used for the continuous determination of dissolved oxygen partial pressure or concentration in liquid media
- 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 within ISO 9001
Who is BS EN 62703 - Expression of performance of fluorometric oxygen analyzers for?
BS EN 62703 on expression of performance of fluorometric oxygen analyzers in liquid media is useful for:
- Chemical industry
- Manufacturers of Analyzers
- Water supplier department
- Testing laboratories
- Industrial companies for streams and liquids process
Why should you use BS EN 62703 - Expression of performance of fluorometric oxygen analyzers?
The measurement of oxygen concentration is of value to many industrial process applications, as well as in environmental monitoring of both gases and liquids. This has resulted in oxygen being one of the most commonly measured chemical species, and understandably the measurement of oxygen represents a substantial component of the process analyzer market.
BS EN 62703 helps to evaluate the amount of dissolved oxygen in the water that must be maintained at ideal levels for industrial processes and assess water quality because of its influence on the organisms living within a body of water.
BS EN 62703 provides guidelines for the manufacturers of fluorometric oxygen analyzers, sensor units, and electronic units to ensure the devices are made as per the standard guidelines.
BS EN 62703 guides you with what tests should be performed to determine dissolved oxygen partial pressure or concentration and how such tests should be carried out. BS EN 62703 helps you provide basic documents to support the application of standards of quality assurance.
