1.1本标准规定了起动电池额定电压高达24V的内燃机动力卡车（以下简称“卡车”）的电气设备设计和施工的电气及相关机械安全要求。 注1本标准的第3部分详细列出了内燃机动力卡车电力传输系统的具体电气要求。 注2:参考其他标准中的本标准，涵盖各种工业卡车类型的非电气要求。 注3:本欧洲标准不涵盖在潜在爆炸性环境中操作的特殊要求。 1.2本标准的要求适用于卡车在以下气候条件下运行时: - 最高环境温度，连续工作:40°C; - 最低环境温度:-20°C; - 服务高度:2000米; - 相对湿度:在30％至95％（非冷凝）的范围内。 1.3本标准涵盖在卡车预期使用过程中可能发生的特定危险。对于在施工，运输，调试，退役和弃置期间发生的危险，应参照EN ISO 12100-2:2003

1.1 This standard specifies the electrical and related mechanical safety requirements for the design and construction of the electrical installation in internal combustion engine powered trucks (hereinafter referred to as "trucks") with starter battery nominal voltages up to and including 24 V. NOTE 1 Part 3 of this standard details specific electrical requirements for electrical power transmission systems of internal combustion engine powered trucks. NOTE 2 Reference is made to this standard in other standards which cover the non-electrical requirements of the various industrial truck types. NOTE 3 The special requirements for operation in potentially explosive atmospheres are not covered in this European Standard. 1.2 The requirements of this standard are applicable, when trucks are operated under the following climatic conditions: - Maximum ambient temperature, continuous duty: +40 °C; - Lowest ambient temperature: -20 °C; - Service altitude: up to 2000 m; - Relative humidity: in the range 30 % to 95 % (non condensing). 1.3 This standard covers specific hazards which could occur during the intended use of trucks. For hazards occurring during construction, transportation, commissioning, decommissioning and disposal, reference should be made to EN ISO 12100-2:2003.
