Factory Acceptance Testing (FAT) is an end-of-line quality inspection performed before shipment to verify conformance to manufacturer and designer standards.

• A. End-of-line quality inspection to ensure equipment meets manufacturer and designer standards
• B. On-site commissioning after installation
• C. Third-party certification
• D. Routine maintenance testing

Answer: (A)

Factory Acceptance Testing is about checking the product right at the factory, after assembly, to ensure it meets the designer’s and manufacturer’s specifications before it is shipped. This end-of-line verification catches any deviations early, proving the unit performs as intended and satisfies contractual requirements before it leaves the facility.

The other concepts describe different stages: on-site commissioning happens after installation to validate operation in the actual environment; third-party certification is independent verification by an external body; routine maintenance testing is ongoing checks performed after deployment to maintain performance.
