IEC 61207-6:20 14适用于使用光度技术测量气体或蒸汽混合物中一种或多种组分浓度的分析仪的所有方面。它应与IEC 61207-1结合使用。它规定: -与利用光度分析仪连续测量源气体中的气体或蒸气浓度的气体分析仪的功能性能相关的术语和定义； -它统一了用于制定和验证有关此类分析仪功能性能的声明的方法； -它规定了应进行哪些测试以确定功能性能以及应如何进行此类测试，并提供了支持质量保证ISO 9001标准应用的基本文件。第二版取消并取代了1994年出版的第一版，构成了技术修订。主要变化有: -所有参考文献（规范性和信息性）均已酌情更新、删除或添加。 -与文件有关的所有术语和定义已酌情更新。 -增加了通用光度设备和测量的新定义。 -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。 -图A.1、A.2。

IEC 61207-6:2014 applies to all aspects of analyzers using photometric techniques for the measurement of concentration of one or more components in a mixture of gases or vapors. It should be used in conjunction with IEC 61207-1. It specifies:
- the terminology and definitions related to the functional performance of gas analyzers, utilizing a photometric analyzer, for the continuous measurement of gas or vapor concentration in a source gas;
- it unifies methods used in making and verifying statements on the functional performance of such analyzers;
- it specifies what tests should be performed to determine the functional performance and how such tests should be carried out and it provides basic documents to support the application of standards of quality assurance ISO 9001. This second edition cancels and replaces the first edition published in 1994 and constitutes a technical revision. The major changes are:
- All references (normative and informative) have been updated, deleted or added to as appropriate.
- All the terms and definitions relating to the document have been updated where appropriate.
- New definitions have been added for generic photometric equipment and measurements.
- All references to "errors" have been replaced by "uncertainties" and appropriate updated definitions applied.
