IEC 61207-1:20 10规定了所有气体分析仪通用的术语、定义、制造商声明和测试要求。它适用于指定永久安装在任何位置（室内或室外）的分析仪，以及利用样品处理系统或原位测量技术的此类分析仪。当由一个制造商作为一个整体单元提供时，它适用于由所有机械、电气和电子部分组成的完整分析仪。当单独或由不同制造商提供时，它也适用于单独的传感器单元和单独的电子单元。第二版取消并取代了1994年出版的第一版，构成了技术修订。与第一版相比的重大技术变化如下:-酌情更新、删除或增加了所有参考文献（规范性和信息性）； -与本国际标准有关的所有术语和定义均已更新； -所有提及“错误”的地方均由“不确定性”取代，并应用适当的更新定义。 如果性能规格仅引用一个值，例如整个测量范围内的固有不确定性、线性不确定性或重复性，则该值现在被定义为最大值，而不是平均值或“代表性”值。这是以前未定义的。在使用零量程和100%量程校准气体的情况下，现在有一个明确的要求，即分析仪必须能够在其正常测量范围之外的标准性能规格内响应，以允许记录仪器的任何低于或高于响应。增加了一个新的附件A，给出了建议的影响标准值。

IEC 61207-1:2010 specifies the terminology, definitions, requirements for statements by manufacturers and tests that are common to all gas analyzers. It is applicable to analyzers specified for permanent installation in any location (indoors or outdoors) and to such analyzers utilizing either a sample handling system or an in situ measurement technique. It is applicable to the complete analyzer when supplied by one manufacturer as an integral unit, comprised of all mechanical, electrical and electronic portions. It also applies to sensor units alone and electronic units alone when supplied separately or by different manufacturers. This second edition cancels and replaces the first edition published in 1994 and constitutes a technical revision. The significant technical changes with respect to the first edition are the following:
- all references (normative and informative) have been updated, deleted or added, as appropriate;
- all the terms and definitions relating to this International Standard have been updated;
- all references to "errors" have been replaced by "uncertainties" and appropriate updated definitions applied.
Where only one value is quoted for a performance specification, such as intrinsic uncertainty, linearity uncertainty or repeatability throughout a measurement range, this has now been defined as the maximum value, rather than an average or "representative" value. This was previously undefined. Where zero and 100 % span calibration gases are used, there is now a defined requirement that the analyser must be able to respond within its standard performance specifications beyond its normal measurement range, to allow for any under or over response of the instrument to be recorded. A new Annex A has been added giving recommended standard values of influence.
