Interview Questions for Testing and Commissioning

Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) are crucial stages in the commissioning process, both verifying the functionality of a system but in different locations. Think of it like this: FAT is the final check at the manufacturer’s facility, while SAT is the final check at your project site.

• FAT (Factory Acceptance Testing): This testing is performed at the vendor’s or manufacturer’s facility before the equipment is shipped to the project site. It involves verifying that the equipment meets the specified requirements outlined in the contract. This typically includes functional tests, performance tests, and safety checks. For example, if we’re commissioning a new HVAC unit, the FAT would involve testing the cooling and heating capacity, verifying the control system’s operation, and ensuring all safety mechanisms are working as designed. The client is usually present during this phase for witnessing the tests.

• SAT (Site Acceptance Testing): This testing takes place at the project site after the equipment has been installed and integrated into the overall system. SAT focuses on verifying the correct integration and functionality within the overall system. For the same HVAC unit, the SAT would involve checking the unit’s integration with the building’s control system, ensuring proper airflow, and verifying its performance in the actual site conditions. It also accounts for potential interactions with other equipment and building systems.

The key difference lies in the location and context of the testing. FAT focuses on individual equipment, while SAT confirms the integrated system’s performance within the intended environment.
