The Factory Acceptance Test (FAT) is an inspection and approval process for a product at the manufacturer's facility before it is delivered to the customer. The goal of the FAT is to verify the functionality and quality of the equipment under controlled conditions to ensure it meets the specified requirements. Following delivery to the customer, a Site Acceptance Test (SAT) is typically conducted, which tests the product at the customer's final location to verify proper installation and operational readiness. These tests are critical steps in the quality management process to ensure that the product meets the requirements and functions reliably.
