This document describes the basic requirements of a type test program with the objective of verifying that a module used as Class 1E equipment in a nuclear power generating station meets or exceeds its design specifications. This document is limited to class 1E modules from and including the sensor through the logic circuitry of the. final actuation devices. Except for those that are part of a module@ switchgear@ cables@ connections@ motors@ valve actuators@ station batteries@ and penetrations are not included and are covered by other IEEE documents.
