本技术报告定义了如何使用高性能的保护装置 高空核电磁脉冲（HEMP）防护 规定了民用系统。性能要求将是 在未来的IEC标准中给出。本技术报告旨在 用于协调现有或未来的规范 由保护装置制造商、电子设备制造商发布 制造商、管理机构和其他买家。 本技术报告涵盖了目前用于 对大麻辐射电磁场的防护。一般来说，参数 与HEMP相关，即与快速变化相关的参数 讨论了电磁场随时间的变化规律。

This technical report defines how protective devices for High Altitude Nuclear Electromagnetic Pulse (HEMP) protection of civilian systems are specified. Performance requirements will be given in future IEC standards. This technical report is intended to be used for the harmonization of existing or future specifications issued by protective devices manufacturers, electronic equipment manufacturers, administrative bodies and other buyers. This technical report covers protective devices currently used for protection against HEMP radiated EM fields. In general, parameters relevant to HEMP, that is parameters related to very fast changes of EM fields, as a function of time, are dealt with.
