本航空航天推荐规程（ARP）描述了用于测试短时间闭式循环或半闭式循环呼吸装置的试验设备和方法，这些装置设计用于在呼吸回路中的高氧分压下运行。本标准旨在补充ARP1109和ARP1398，以适用于可能根据AS8031和/或AS8047的要求进行评估的闭式循环或半闭式循环呼吸设备。本ARP建议对航空防护呼吸设备（PBE）测试中用于模拟人体呼吸的测试设备的性能要求。 然而，该ARP并不排除人体试验的需要。

This Aerospace Recommended Practice (ARP) describes test equipment and methods used for testing closed cycle or semiclosed cycle breathing devices of short duration that are designed to operate with a high partial pressure of oxygen in the breathing circuit. It is intended to supplement ARP1109 and ARP1398 for applications involving closed cycle or semiclosed cycle breathing equipment which may be evaluated to the requirements of AS8031 and/or AS8047.This ARP recommends performance requirements for test equipment used to simulate human respiration in the testing of aviation protective breathing equipment (PBE). This ARP doeS not, however, preclude the need for human testing.
