确定稀释器需求、自动压力呼吸、氧气调节器的最佳设计、结构和性能标准。AS 861《氧气系统最低通用标准》适用于本规范的补充。本文件部分取代已取消的AS 463，12-15-56。本规范涵盖民用飞机上使用的两种稀释器需求、自动压力呼吸和氧气调节器。其目的是调节器有两种配置，可在40至90 psig和50至150 psig的入口压力下操作。

To define optimum standards of design, construction and performance for Diluter Demand, Automatic Pressure Breathing, Oxygen Regulators. AS 861, 'Minimum General Standards for Oxygen Systems,' is applicable as supplemented by this specification. This document supersedes in part AS 463, 12-15-56, which is cancelled. This specification covers two types of Diluter Demand, Automatic Pressure Breathing, Oxygen Regulators for use in civil type aircraft. The intent is that the regulators be of two configurations, operable at inlet pressures of 40 to 90 psig and 50 to 150 psig.
