ISO 27470:2011规定了餐饮车辆的最低功能、性能和安全要求，该车辆能够向超大型飞机的上层甲板以及这些或其他类型飞机的主甲板运输和装卸机上服务（餐饮）设备和用品。 ISO 27470:2011的目的不是指定设备设计，而是定义最低功能和性能要求，并强调那些已知对民用运输机在国际机场环境中高效和安全运行至关重要的标准。 ISO 27470:2011规定了飞机和车辆制造商以及航空公司和餐饮机构认可的全球要求。此外，应适当参考车辆运营所在国的国家政府法规。此类国家法规可能适用的主要但非排他性领域是:a)适用于道路车辆的一般要求；b)有关用于运载供人食用的食物的车辆的设计、清洁和消毒的卫生要求；c)适用于在高架位置运载人员的升降设备的稳定性和其他安全要求。 然而，ISO 27470:2011中的任何内容都不应被视为取代任何当地适用的法律或法规，除非已为此目的从适当机构获得特定豁免。 ISO 27470:2011的某些要求是由某些飞机类型的舱门的机翼上通道具体规定的，并且可能不适用于其他飞机类型。然而，ISO 27470:2011的意图是任何上层餐饮车辆都应能够安全地处理这种特定情况。

ISO 27470:2011 specifies the minimum functional, performance and safety requirements for a catering vehicle capable of transporting and loading/unloading in-flight service (catering) equipment and supplies into or from the upper deck of very large capacity aircraft, as well as the main deck of these or other aircraft types. The intent of ISO 27470:2011 is not to specify equipment design, but rather to define minimum functional and performance requirements and highlight those criteria which are known to be essential to an efficient and safe operation on civil transport aircraft in the environment of international airports. ISO 27470:2011 specifies the worldwide requirements recognized by aircraft and vehicle manufacturers as well as airlines and catering agencies. In addition, it shall be applied with due reference to the national governmental regulations of the country where the vehicle is to be operated. The main though not exclusive areas in which such national regulations may apply are: a) general requirements applicable to road vehicles; b) sanitary requirements regarding design, cleaning and disinfection of vehicles used to carry food for human consumption; c) stability and other safety requirements applicable to elevating equipment carrying personnel in the elevated position. Nothing in ISO 27470:2011, however, shall be deemed to supersede any locally applicable law or regulation, unless a specific exemption has been obtained for this purpose from the appropriate Authority. Certain requirements of ISO 27470:2011 are specifically dictated by overwing access to doors of certain aircraft types, and may not apply to other aircraft types. However, the intent of ISO 27470:2011 is that any upper deck catering vehicle shall be capable of safely handling this specific situation.
