SAE J2064的范围包括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制冷剂的连接软管组件。从历史上看，SAE J2064中包含了用于耦合汽车制冷剂空调总成的软管要求。已对SAE J2064进行了更改，以确定工厂和现场连接软管组件的要求。发布SAE J3062是为了将这些组件中使用的软管的要求定义为其自己的标准。SAE J2064还提供了SAE J2727中使用的必要值。MAC软管总成的认证联轴节是满足某些法规要求所必需的。已满足SAE J3062要求并通过SAE J2911认证的软管应作为联轴节总成的一部分。符合SAE J3062要求的软管不能确保总成符合SAE J2064的要求。 软管组件制造商有责任确认组件符合本规范规定的验收标准。软管组件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℃的温度范围内发挥作用。具体的结构细节将由用户和供应商商定。2015年发布本标准之前生产的散装软管可能标有SAE J2064，可能不符合SAE J3062的要求。

The scope of SAE J2064 covers coupled hose assemblies intended for containing and circulating lubricant, liquid, and gaseous R-134a, R-152a, and/or R-1234yf refrigerant in automotive air-conditioning systems. Historically, requirements for the hose used in coupled automotive refrigerant air conditioning assemblies was included in SAE J2064. SAE J2064 has been changed to establish the requirements for factory and field coupled hose assemblies. SAE J3062 has been issued to define requirements for the hose used in these assemblies into its own standard. SAE J2064 also provides the necessary values used in SAE J2727. The certified coupling of MAC hose assemblies is required in meeting certain regulatory requirements.A hose which has met the requirements of SAE J3062 and certified in SAE J2911 shall be used as part of the coupled assembly. A hose which meets the requirements of SAE J3062 does not ensure the assembly will meet the requirements of SAE J2064. It is the hose assembly manufacturer¿¿¿s responsibility to confirm that the assemblies meet the specified acceptance criteria for this specification. The hose assembly 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 user and supplier.Bulk hose produced prior to the release of this standard in 2015 could be labeled ¿¿¿SAE J2064¿¿¿ and may not meet the requirements of SAE J3062.
