标准摘要
[中文适用范围]： IEC 60746 的这一部分旨在： ?规定用于测定溶解氧分压或浓度的分析仪、传感器单元和电子单元的术语、定义和制造商声明的要求； ？为此类分析仪、传感器单元和电子单元建立性能测试； ？提供支持质量保证标准应用的基础文件[1]1。本文件适用于使用覆膜电流传感器的分析仪。它适用于适用于含有液体@超纯水@淡水或饮用水@海水或其他水溶液@来自水体的工业或城市废水@（例如湖泊@河流@河口）@以及工业过程的分析仪流和过程液体。虽然原则上安培氧分析仪适用于气相，但气相性能的表达超出了本文件的范围。本文件适用于指定使用覆膜电流传感器永久安装在任何位置（室内或室外）的分析仪 1 方括号中的数字指的是参考书目 [外文原描述]： 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. This edition includes the following significant technical changes with respect to the previous edition: a) terms and definitions have been revised to meet the requirements of ISO/IEC Directives Part 2:2016. b) ISO 5814:2012 is cited as reference for solubility tables of dissolved oxygen in water with variable salt content at different pressure and temperature.
