IEC 60079-29-3:20 14为固定气体检测系统的设计和实施提供了指南，包括相关和/或外围气体检测设备，用于根据IEC 61508和IEC 61511在安全相关应用中使用时检测易燃气体/蒸汽和氧气。本国际标准也适用于有毒气体的检测。本国际标准的其他部分以及相关的地方、国家和国际标准分别规定了气体检测仪和气体检测控制单元（逻辑解算器）的性能要求。这些标准通常称为计量性能标准，涉及测量值的准确性、整体系统性能，但不涉及设备或系统在安全功能方面的完整性。本国际标准适用于安全功能的完整性。 关键词:固定式气体检测系统可燃气体/蒸气和氧气有毒气体检测 本出版物应与IEC 60079-0:20 11、IEC 60079-29-1:20 07、IEC 60079-29-2:20 07和IEC 60079-29-4:20 09一起阅读

IEC 60079-29-3:2014 gives guidance for the design and implementation of a fixed gas detection system, including associated and/or peripheral gas detection equipment, for the detection of flammable gases/vapours and oxygen when used in a safety-related application in accordance with IEC 61508 and IEC 61511. This International standard also applies to the detection of toxic gases. Other parts of this international standard and pertinent local, national and international standards separately specify the performance requirements of a gas detector and a gas detection control unit (logic solver). These standards are commonly known as Metrological Performance Standards and are concerned with the accuracy of the measured value, the overall system performance, but not the device or system integrity with respect to the safety function. This international standard applies to the integrity of the safety function. Keywords: fixed gas detection system, flammable gases/vapours and Oxygen, detection of toxic gases
