ANSI/ISA-60079-29的本部分规定了结构、测试和性能的一般要求，并描述了适用于便携式、可运输和固定式设备的测试方法，用于检测和测量可燃气体或蒸汽的空气浓度。该设备或其部件拟用于爆炸性气体环境和易受沼气影响的矿井。现行版本标准ANSI/ISA-60079-29-1（12.13.01）-2013继承了ANSI/ISA-12.13.01-2002（IEC 61779-1至5 Mod），允许使用现行版本或之前的一个版本进行认证机构认证和产品重新认证。

This part of ANSI/ISA-60079-29 specifies general requirements for construction, testing and performance, and describes the test methods that apply to portable, transportable and fixed apparatus for the detection and measurement of flammable gas or vapour concentrations with air. The apparatus, or parts thereof, are intended for use in explosive gas atmospheres and in mines susceptible to firedamp.The current edition standard ANSI/ISA-60079-29-1 (12.13.01)-2013 succeeds ANSI/ISA-12.13.01-2002 (IEC 61779-1 through 5 Mod) allowing for the use of the current edition or one previous edition to be valid for approval agency accreditation and product re-certification.
