Factory Acceptance Testing Explained
What is Factory Acceptance Testing?
Factory acceptance testing (FAT) is a structured process carried out at the manufacturer’s facility to confirm that newly built machinery or equipment performs exactly as intended before it ever reaches the customer’s site. A factory acceptance inspection verifies that the equipment meets the agreed specification, operates safely, and delivers the functionality required for its intended purpose. This stage gives the end user confidence that the system is compliant, reliable, and ready for installation. The outcome is typically documented in a factory acceptance test report or certificate, forming a clear record of the checks completed, the results achieved, and any actions required before shipment.

Know Your Obligations
When Do You Need Factory Acceptance Testing?
Factory acceptance testing is required at key stages in the procurement of new machinery or equipment, especially when safety, reliability, or contractual compliance must be demonstrated before delivery. You typically need FAT when:
-
Purchasing new or custom‑built machinery — To confirm the equipment meets the agreed specification and performs as intended before it leaves the manufacturer.
-
Installing complex or safety‑critical systems — Such as automated production lines, integrated control systems, or machinery with significant safety functions where early validation reduces commissioning risks.
-
Meeting contractual or project requirements — Many supply agreements specify that a factory acceptance test certificate or test report must be issued before shipment or final payment.
-
Ensuring compliance with UK and EU machinery legislation — While FAT itself is not a legal requirement, it provides documented evidence that the equipment operates safely and correctly, supporting compliance with the Supply of Machinery (Safety) Regulations and the Machinery Directive.
-
Reducing on‑site delays and installation issues — Identifying faults or non‑conformities at the factory prevents costly downtime once the equipment arrives on site.
-
Verifying integration with other equipment — When machinery must interface with existing systems, FAT confirms compatibility and correct operation before installation.
