Public shelters have to successfully pass commissioning tests before being issued a Notice of Approval of Commissioning (NOAC) and consequently, the Certificate of Statutory Completion (CSC).
Commissioning tests

To ensure that |
| Internal overpressure test |

|
| Overpressure regime and airflow test |
The air supply system can regulate airflow through the ducts, dampers and CD valves in accordance with the functions and requirements of the shelter
|
| Integrated systems test |
All systems in the shelter continue to function properly and reliably under normal supply when switching to the standby generator set
|
