BS EN IEC 60746-4:2019

This standard BS EN IEC 60746-4:2019 Expression of performance of electrochemical analyzers is classified in these ICS categories:

• 19.080 Electrical and electronic testing
• 71.040.40 Chemical analysis

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.
