ISO 21308系列描述了卡车底盘制造商和车身制造商之间数据交换的通用系统。它适用于ISO 3833中定义的商用车辆，其最大车辆总质量超过3500 kg。 交换上述信息的过程可能涉及底盘制造商、底盘进口商、底盘经销商、一个或多个车身制造商和车身部件供应商，例如可拆卸车身、起重机和装载设备以及倾卸设备的制造商。 ISO 21308-5:2014专门描述了装载机起重机和辅助稳定器的编码尺寸和其他特性，以确保相关方之间高效、明确地沟通安装数据。 ISO 21308-5:2014涵盖了ISO 15442中规定的装载机起重机，设计用于安装在商用车辆（包括拖车）上。 ISO 21308-5:2014不适用于其他载荷提升系统（例如尾部提升机、吊钩装载机系统）。

The ISO 21308 series describes a generic system for the exchange of data between truck chassis manufacturers and bodywork manufacturers. It applies to commercial vehicles as defined in ISO 3833, having a maximum gross vehicle mass above 3 500 kg. The process of exchanging the above information can involve chassis manufacturers, chassis importers, chassis dealers, one or more bodywork manufacturers, and bodywork component suppliers, e.g. manufacturers of demountable bodies, cranes and loading equipment, and tipping equipment. ISO 21308-5:2014 specifically describes the coding dimensions and other characteristics of loader cranes and auxiliary stabilizers, to ensure an efficient and unambiguous communication of installation data between the parties involved. ISO 21308-5:2014 covers loader cranes as specified in ISO 15442, designed to be fitted on commercial vehicles (including trailers). ISO 21308-5:2014 is not applicable to other load-lifting systems (e.g. tail lifts, hook loader systems).
