本标准描述了核电站安全壳外1E级装置的静态电池充电器、逆变器和不间断电源（UPS）系统的鉴定方法，不适用于恶劣环境（如安全壳内）设计基准条件下的鉴定。

This standard describes methods for qualifying static battery chargers, inverters, and uninterruptible power supply (UPS) systems for Class 1E installations outside containment in nuclear power generating stations, and is not intended for qualification under harsh environment (e.g., inside containment) design basis conditions.
