The objective of the Mission Critical Environment Integrated System Testing (IST) (DC´s , Control Towers, etc.) is to verify system performance and redundancy in normal conditions, and maintenance and failure operation due to system specification, operational memory and Owner or Operator requirements. All combinations of possible failures of components and equipment are tested and validated onsite to ensure performance in the different operational modes as well as the operational continuity of these systems:
- Redundancy in facilities
- Operation in emergency mode
- Operation in failure mode
- Operation in maintenance mode
Possible results include validation without observations or with constraints and/or recommendations: design (operational constraints or limitations), execution (operational constraints or limitations) and commissioning (correctable issues).
