气体分析仪性能表示法第2部分:用高温电化学传感器测量气体中的氧

[中文适用范围]： IEC 61207-2适用于使用高温电化学传感器测量气体中氧气的所有分析仪方面。它适用于原位和分析器以及室内和室外安装的分析仪。本部分的目的是：指定与利用高温电化学传感器连续测量气体样品中氧浓度的气体分析仪功能性能相关的术语和定义；统一用于制定和验证此类分析仪功能性能声明的方法；指定为确定功能性能而执行的测试以及执行此类测试的方法；提供支持应用国际认可的质量管理标准的基本文件。 [外文原描述]： IEC 61207-2:2019 applies to all aspects of analyzers using high-temperature electro¬chemical sensors for the measurement of oxygen in gas. It applies to in-situ and extractive analyzers and to analyzers installed indoors and outdoors. The object of this part is: – to specify the terminology and definitions related to the functional performance of gas analyzers, utilizing a high-temperature electrochemical sensor, for the continuous measurement of oxygen concentration in a sample of gas; – to unify methods used in making and verifying statements on the functional performance of such analyzers; – to specify what tests are performed to determine the functional performance and how such tests are carried out; – to provide basic documents to support the application of internationally recognized quality management standards. This second edition cancels and replaces the first edition published in 1994. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition. a) all the terms and definitions relating to the document have been updated where appropriate; b) the description of the principle of the galvanic cell has been expanded and clarified; c) new definitions and illustrations have been added for different measurement methods for oxygen using solid electrolytes for galvanic cells; d) new illustrations have been added for existing descriptions for ion pump cells; e) a more detailed description of the effect of the presence of oxidizable gases has been added; f) all references to “errors” have been replaced by “uncertainties” and appropriate updated definitions applied.
