Superseded by IEEE Std 650-2006. Methods for qualifying static battery chargers and inverters for Class 1E installations in a mild environment outside containment in nuclear power generating stations are described. The qualification methods set forth employ a combination of type testing and analysis, the latter including a justification of methods, theories, and assumptions used. These procedures meet the requirements of IEEE Std 323-1983, IEEE Standard for Qualifying Class 1E Equipment for Nuclear Power Generating Stations.

This standard describes methods for qualifying static battery chargers and inverters for Class 1E installations in a mild environment outside containment in nuclear power generating stations. The application of this equipment in the plant's electrical system is not within the scope of this standard as other industry standards, such as IEEE Std 308-1980, IEEE Std 603-1980, and IEEE Std 946-1985, exist for this purpose. In addition, industry standards exist for equipment performance, such as ANSI/NEMA PE 5-1985. Performance requirements are not specified in this standard.
