建立用于检测缺氧/富氧环境的仪器的安装、操作和维护的用户标准。ISA/S92中所有氧气检测仪器均应满足ANSI S92推荐的性能要求。04.01，第一部分，用于检测缺氧/富氧环境的仪器的性能要求。

Establishes user criteria for the installation, operation, and maintenance of instruments used to detect oxygen-deficient/oxygen-enriched atmospheres. This Recommended Practice applies to all oxygen detection instruments that satisfy the performance requirements in ANSI/ISA-S92.04.01, Part I, Performance Requirement for Instruments Used to Detect Oxygen-Deficient/Oxygen Enriched Atmospheres.
