IEEE 628-2020 IEEE Standard Criteria for the Design, Installation, and Qualification of Raceway Systems for Class 1E Circuits for Nuclear Power Generating Stations

IEEE 628-2020 Стандарт IEEE Критерии для проектирования, монтажа и квалификация Raceway систем для класса 1E схем для атомных станций, вырабатывающих энергии

This standard contains the requirements for the design, installation, and qualification of raceway systems for Class 1E circuits external to electric equipment and components for nuclear power generating stations. Because aging and radiation have no known detrimental effects on metallic raceway systems and because nonmetallic raceway systems are limited to underground or embedded applications, aging and radiation are not considered in this standard. The embedments or structural members to which a support is attached are beyond the scope of this standard.
