This International Standard provides recommendations for measurements that allow operator diagnosis of developing deviations from normal operation. The operator can then take corrective action at an early stage to prevent a minor failure from developing into a serious plant failure or an accident condition. This standard is directed towards monitoring under normal conditions only in both primary and secondary containment.
