标准摘要
[中文适用范围]: 本部分IEC 60079-29规定了用于检测和测量空气中可燃气体或蒸汽浓度的便携式、移动式和固定式设备的构造、测试和性能的通用要求,并描述了适用的测试方法。该设备或其部分用于易爆环境和易燃气体的矿井。 本部分IEC 60079-29适用于测量范围由制造商声明的任何体积分数的可燃气体检测设备,旨在提供指示、警报或其他输出功能;其目的是指示潜在的爆炸危险,并在某些情况下启动自动或手动保护措施。 对于本部分IEC 60079-29而言,术语“指示高达体积分数X%或X%LFL”包括测量范围上限等于或小于X%或X%LFL的设备。 本部分IEC 60079-29适用于商业、工业和非住宅安全应用的设备,包括抽吸设备的整体采样系统。 本部分IEC 60079-29不适用于外部采样系统,或实验室或科学类型的设备,或仅用于过程监测和/或控制目的的设备。它也不适用于IEC 60079-29-4范围内的开放路径(视线)探测器。只有光学路径非常短且浓度在光学路径上均匀的设备才适用于本标准。 对于用于检测多种气体的设备,本部分IEC 60079-29仅适用于可燃气体或蒸汽的检测。 本部分IEC 60079-29补充和修改了IEC 60079-0的通用要求。如果本标准的要求与IEC 60079-0的要求冲突,则以IEC 60079-29-1的要求为准。 [外文原描述]: IEC 60079-29-1:2016+A1:2020 specifies general requirements for construction, testing and performance, and describes the test methods that apply to portable, transportable and fixed equipment for the detection and measurement of flammable gas or vapour concentrations with air. The equipment, or parts thereof, is intended for use in explosive atmospheres and in mines susceptible to firedamp. This second edition of IEC 60079-29-1 cancels and replaces the first edition of IEC 60079-29-1:2007 series and constitutes a technical revision. Refer to the Forward of the document for a listing of the extensive changes between this edition and the previous edition. The contents of the interpretation sheets 1 and 2 (2019-04) have been included in this copy. This consolidated version of the official IEC Standard and its amendment consists of the second edition (2016) and its amendment 1 (2020). Therefore, no need to order amendments in addition to this publication. Keywords: detection and measurement of flammable gas or vapour concentrations with air, explosive atmospheres, mines susceptible to firedamp, explosion hazard
