气体分析器性能表示.第1部分:总则

[中文适用范围]： IEC 61207的本部分适用于用于测定气体混合物中某些成分的气体分析仪。 IEC 61207 的这一部分规定了所有气体分析仪通用的术语、定义、制造商声明和测试的要求。该系列中的其他国际标准（例如 IEC 61207-2）描述了特定于某些类型（使用高温电化学传感器）的那些方面。本部分 IEC 61207 符合 IEC 60359 和 IEC 60770 中规定的一般原则。本标准适用于指定永久安装在任何位置（室内或室外）的分析仪，以及使用样品处理系统或样品处理系统的分析仪。原位测量技术。本标准适用于由一个制造商作为一个整体单元提供的完整分析仪，由所有机械、电气和电子部分组成。当单独提供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。就本标准而言，任何用于主电源或任何非主电源的调节器（随分析仪提供或由制造商指定）均被视为分析仪的一部分，无论其与分析仪集成还是单独安装。 IEC 61010-1 中涉及安全要求。如果样品中的一种或多种成分是易燃的，并且存在空气或含有氧气或其他氧化成分的另一种气体混合物，则反应成分的浓度范围被限制在不在可燃极限内的水平。 IEC 60381-1 和 IEC 60382 规定了过程控制系统中使用的模拟直流电流和气动信号的标准范围。影响量测试值的规范可在 IEC 60654 中找到。 随仪器提供的文档要求IEC 61187 中处理了有关数量、单位和符号的一般原则的要求，ISO 1000 中处理了。另请参见 ISO 31-0。 [外文原描述]： 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the terms and definitions relating to this International Standard have been updated; - all references to "errors" have been replaced by "uncertainties" and appropriate updated definitions applied.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.
