Site Acceptance Test (SAT)
A Site Acceptance Test (SAT) is a critical phase in the commissioning process of equipment or systems. Conducted at the customer’s site after installation, the SAT verifies that the system operates according to specified requirements in its actual operating environment.
Purpose of SAT
The primary goal of the SAT is to ensure that the installed system meets the customer’s expectations and contractual obligations. It serves as the final validation step before the system becomes fully operational, confirming that all components function correctly and that the system integrates seamlessly into the existing infrastructure.
Key Components of SAT
-
Planning: Developing a comprehensive test plan outlining objectives, methodologies, and acceptance criteria.
-
Execution: Performing tests to assess system functionality, performance, and safety under real-world conditions.
-
Documentation: Recording test results, observations, and any discrepancies encountered during testing.
-
Validation: Reviewing and approving test outcomes to confirm compliance with specified requirements.
SAT vs. FAT
While both the Site Acceptance Test (SAT) and the Factory Acceptance Test (FAT) are essential in the equipment validation process, they differ in location and focus.
-
FAT: Conducted at the manufacturer’s facility to verify that the equipment meets design specifications before shipment.
-
SAT: Performed at the customer’s site to ensure that the equipment functions correctly within the actual operating environment.
In summary, the SAT is a vital step to confirm that the installed system operates as intended in its real-world setting, ensuring readiness for full-scale operation
