本SAE推荐实践主要针对汽油动力客车和卡车应用与蒸汽回收系统接口而开发，但也可用于柴油应用、船舶、工业和需要喷嘴进行加注的类似应用。这些区域覆盖到再填充端口的喷嘴喷口入口和手柄间隙。此外，该实践还包括一个供喷嘴制造商开发的设计窗口。

This SAE Recommended Practice was developed primarily for gasoline-powered passenger car and truck applications to interface vapor recovery systems, but may be used in diesel applications, marine, industrial, and similar applications where a nozzle is required for filling. The zones cover nozzle spout access and handle clearance to a refilling port. In addition, this practice includes a design window for nozzle manufacturers to develop with.
