Commissioning for Data centres and Critical infrastructure is a specialised process designed to ensure that all systems within the facility operate reliably, efficiently, and meet stringent standards. Each element of the commissioning process from Site Acceptance Tests (SATs) through to Integrated Systems Tests (ISTs) is vital to ensure the facility operates without interruption of services.

Commissioning for highly resilient facilities like data centres vary in the level of rigour applied compared to a commissioning program for any other facility.

• Higher witness test rates, less sampling.
• Multiple tests and multiple iterations of these tests every potential scenario or condition must be tested.
• Higher level of test complexity.
• Witness testing of all operation, failure and maintenance scenarios.
• Integrated Systems Test.

Key Components of Data Centre / Critical Infrastructure Commissioning:

• Level 1 - Factory Testing
• Level 2 - Site Acceptance Testing
• Level 3 - Pre-Commissioning
• Level 4 - Functional Performance Testing
• Level 5 - Integrated System Testing
