標(biāo)準(zhǔn)簡介

This part of IEC 60746 is intended:
• to specify terminology, definitions and requirements for statements by manufacturers for
analyzers, sensor units and electronic units used for the determination of dissolved
oxygen partial pressure or concentration;
• to establish performance tests for such analyzers, sensor units and electronic units;
• to provide basic documents to support the applications of quality assurance standards

This document 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.dition 2.0 2018-12 INTERNATIONAL STANDARD NORME INTERNATIONALE Expression of performance of electrochemical analyzers – Part 4: Dissolved oxygen in water measured by membrane-covered amperometric sensors Expression des qualités de fonctionnement des analyseurs électrochimiques – Partie 4: Oxygène dissous dans l'eau mesuré par des capteurs ampérométriques recouverts d'une membrane IEC 60746-4:2018-12(en-fr) THIS PUBLICATION IS COPYR
