SAE J3062的范围涵盖了用于在汽车空调系统中容纳和循环润滑剂、液体和气态R-134a、R-152a和/或R-1234yf制冷剂的软管。软管的设计应尽量减少制冷剂的渗透和系统的污染，并在-30至125°C的温度范围内工作。具体施工细节由用户和供应商商定。 SAE J2064中包含了耦合式汽车制冷剂空调组件中使用的软管的要求。SAE J3062将这些组件中使用的软管的要求分为自己的标准。SAE J2064还提供了SAE J2727中使用的必要制冷剂渗透值。移动式空调系统制冷剂排放率在SAE J2727排放图中规定，非常重要。MAC软管组件的认证联轴器需要满足某些法规要求。 因此，SAE J2064的范围已更改，以建立工厂和现场耦合软管组件的装配要求。符合SAE J3062要求的软管可能不符合SAE J2064的要求。在本标准发布之前生产的散装软管可能被标记为“SAE J2064”，并且可能不符合SAE J3062的要求。

The scope of SAE J3062 covers hose intended for containing and circulating lubricant, liquid, and gaseous R-134a, R-152a, and/or R-1234yf refrigerant in automotive air-conditioning systems. The hose shall be designed to minimize permeation of the refrigerant, contamination of the system, and to be functional over a temperature range of -30 to 125 °C. Specific construction details are to be agreed upon between the user and supplier. Requirements for the hose used in coupled automotive refrigerant air-conditioning assemblies are included in SAE J2064. SAE J3062 separates requirements for the hose used in these assemblies into its own standard. SAE J2064 also provides the necessary refrigerant permeation values used in SAE J2727. Mobile air-conditioning system refrigerant emissions rates are established in SAE J2727 emission charts and are important. The certified coupling of MAC hose assemblies is required in meeting certain regulatory requirements. Therefore, the scope of SAE J2064 has been changed to establish the assembly requirements for factory and field coupled hose assemblies. A hose which meets the requirements of SAE J3062 may not meet the requirements of SAE J2064. Bulk hose produced prior to the release of this standard could be labeled “SAE J2064” and may not meet the requirements of SAE J3062.
