FAT The Factory Acceptance Test (FAT) is a process that evaluates the equipment during and after the assembly process by verifying that it is built and operating in accordance with design specifications. FAT ensures that the components and controls are working properly according to the functionality of the equipment itself.
FAT is typically conducted in order to assess any discrepancies and non-conformities, as well as develop a process for how they are to be handled. Deviations or abnormalities observed during testing are documented in a problem report and corrected prior to shipment.
FAT must be conducted in a thorough and forthright manner. A poor or rushed FAT can lead to missed non conformities, which can only then be corrected after the equipment is installed—which in turn can wreak havoc on a project schedule.
