ISO/TS 21609:2014给出了在道路车辆上安装射频（RF）发射和接收设备的要求和建议，以及可移动和手持射频设备的“道路车辆内”安装套件，以及与之相关的辅助设备。 除安装方法外，还制定了将已安装设备与车辆电气和电子系统之间的电磁干扰（EMI）可能性降至最低的方法。

ISO/TS 21609:2014 gives requirements and recommendations for the installation in road vehicles of radio frequency (RF) transmitting and receiving equipment, "in-road-vehicle" mounting kits for transportable and hand-held RF equipment, and ancillary equipment associated with these. As well as methods for installation, it establishes methods for minimizing the possibility of electromagnetic interference (EMI) between the installed equipment and the vehicle electrical and electronic systems.
