GB/T 20245.4-2013 "Expression of performance of electrochemical analyzers - Part 4: Dissolved oxygen in water measured by membrane-covered amperometric sensors" specifies the methods for expressing the performance of electrochemical analyzers that continuously measure the partial pressure or concentration of dissolved oxygen in water using membrane-covered amperometric sensors. This standard applies to dissolved oxygen analyzers used for monitoring drinking water, industrial process water, various types of wastewater, and natural water bodies (such as rivers and lakes). It provides a unified description of their metrological characteristics, test conditions, and performance indicators.
