Description

Revision Standard – Active. The independence requirements of the circuits and equipment comprising or associated with Class 1E systems are described in this standard. Criteria for the independence that can be achieved by physical separation and electrical isolation of circuits and equipment that are redundant are set forth. The determination of what is to be considered redundant is not addressed.
