制冷剂12汽车的空调软管

[中文适用范围]： 该 SAE 标准涵盖用于在汽车空调系统中传导液态和气态二氯二氟甲烷（制冷剂 12）的增强软管@或软管组件@。软管的设计应尽量减少制冷剂 12 的渗透和系统的污染，并可在 ℃30 至 120℃（℃22 至 248℃）的温度范围内使用。具体的结构细节应由用户和制造商商定。供应商1 注-R12 制冷剂由于其臭氧消耗特性已被列入禁用物质清单。随着新的汽车空调系统使用 R134a，SAE J51 规范将逐步淘汰。SAE J2064 是制冷剂 134a 软管的标准。对于制冷剂 134a，请参阅 SAE J2064。1 本规范中引用的测试是实验室测试@，用于建立性能标准。 [外文原描述]： This SAE Standard covers reinforced hose, or hose assemblies, intended for conducting liquid and gaseous dichlorodifluoromethane (refrigerant 12) in automotive air-conditioning systems. The hose shall be designed to minimize permeation of refrigerant 12 and contamination of the system and to be serviceable over a temperature range of −30 to 120 °C (−22 to 248 °F). Specific construction details are to be agreed upon between user and supplier. 2xNOTE—R12 refrigerant has been placed on a banned substance list due to its ozone depletion characteristics. SAE J51 specification will be phased out as new automotive A/C systems are using R134a. SAE J2064 is the Standard for refrigerant 134a hose. For refrigerant 134a use, refer to SAE J2064.Cross Reference: ASTMD380,J2064_201508,J343_201605
