ISO 14990.3:2022同样采用ISO 14990 3:2016，其中规定了自供电（利用车载电源）电动土方机械（EMM）中电气设备及其部件的特殊安全要求。它适用于在任何频率下使用50 V36 kV AC r.m.s.和75 V36 kV DC（包括户外使用的任何脉冲直流重复频率）范围内的车载电压的机器。

AS ISO 14990.3:2022 identically adopts ISO 14990 3:2016, which specifies the particular safety requirements for the electrical equipment and its components incorporated in self-powered (utilizing on-board electric power sources) electrically-driven earth-moving machines (EMMs). It is applicable to those machines using on-board voltages in the range of 50 V–36 kV AC r.m.s. at any frequency, and 75 V–36 kV DC — including any repetition rate of pulsating DC— intended for outdoor use.
