本文件已被宣布为“稳定”，不再接受货币定期审查。用户负责验证参考资料和持续适用性或技术要求。新技术可能存在。本SAE标准涵盖增强橡胶、增强热塑性塑料或其他构造的软管或软管组件，用于将液态和气态制冷剂从移动式空调系统输送至维修设备（如歧管仪表组和真空泵）或内部使用，用于维修移动空调系统的充电站或维修设备。软管的设计应尽量减少制冷剂的渗透和流经软管的制冷剂的污染，并可在以下温度范围内使用:- 30至95摄氏度。软管工作压力应至少为3.4 MPa，最小破裂压力应至少为5倍。

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist.This SAE Standard covers reinforced rubber, reinforced thermoplastic, or otherwise constructed hose, or hose assemblies, intended for conducting liquid and gaseous refrigerants for service connections from mobile air conditioning systems to service equipment such as a manifold gauge set and vacuum pumps or for use internally, in charging stations or service equipment intended for use in servicing mobile air-conditioning systems.The hose shall be designed to minimize permeation of refrigerants and contamination of refrigerant passing there through and to be serviceable over a temperature range of -30 to 95 degrees C. Hose working pressures shall be at least 3.4 MPa and the minimun burst pressure shall be at least 5 times.
