BS ISO 14990-3:2016规定了电气设备及其附件的特殊安全要求 自供电（利用车载电源）电动驱动中包含的部件 土方机械（EMM）。它适用于在任何条件下使用50 V-36 kV AC r.m.s.范围内车载电压的机器 频率，以及75 V-36 kV直流电（包括脉动直流电的任何重复频率），用于户外使用。发生在设备内的电压不被视为车载电压，因此不在 它的范围。它将与ISO 14990一起使用- 1，给出了EMM的一般要求 不管它们是如何供电的。外部动力机器的具体要求如下: 在ISO 14990-2中给出。EMM既可以是自供电的，也可以是外部供电的 （例如，具有内置充电器和电源功能的电池供电机器），在这种情况下 ISO 14990-2也适用。注释:对于拟在道路上操作的机器，汽车标准ISO 6469和/或UN ECE R100 可能会提供有用的指导。有关要求的比较，请参见附录B。交叉引用: ISO 14990-1:2016ISO 14990-2ISO 3457:2003ISO 6469-1ISO 6469-2ISO 6469-3:2011ISO 12100ISO 13766ISO 15998ISO 20474IEC 60034IEC 60204-1:2009IEC 60204-11IEC 60417IEC 60664UN ECE R100:2011购买本文件时提供的所有当前修订版均包括在内。

BS ISO 14990-3:2016 specifies the particular safety requirements for the electrical equipment and its components incorporated in self-powered (utilizing on-board electric power sources) electricallydriven 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.Voltages occurring within devices are not considered to be on-board voltages and are thus not within its scope.It is intended to be used in conjunction with ISO 14990-1, which gives general requirements for EMMs regardless of how they are powered. Requirements specific to externally-powered machines are given in ISO 14990-2. It is possible to have an EMM that is both self-powered and externally powered (e.g. a battery powered machine having a built-in charger with power supply function), in which case ISO 14990-2 is also applicable.NOTE For machines intended to be operated on-road, automotive standard ISO 6469 and/or UN ECE R100 may provide useful guidance. See Annex B for a comparison of requirements.Cross References:ISO 14990-1:2016ISO 14990-2ISO 3457:2003ISO 6469-1ISO 6469-2ISO 6469-3:2011ISO 12100ISO 13766ISO 15998ISO 20474IEC 60034IEC 60204-1:2009IEC 60204-11IEC 60417IEC 60664UN ECE R100:2011All current amendments available at time of purchase are included with the purchase of this document.
