Contract documents
Signed technical scope, approved drawings, equipment list, component requirements and acceptance points.
FAT connects the order to evidence
Prepare FAT Around the Signed Scope and Real Test Conditions
A useful factory acceptance test checks agreed equipment and functions, records limitations and leaves a controlled action list before shipment.
01
Prepare the test basis
The FAT plan should be reviewed before travel or the test date.
Test materials
Confirmed containers, caps, labels, product substitutes and packing materials in sufficient quantity.
Test conditions
Utilities, run duration, speed basis, product basis and known factory-test limitations.
Participants and records
Name witnesses, language, measurements, photos, video, documents and sign-off authority.
02
Inspect and test in layers
Move from identity and safety checks to functions and agreed integrated behavior.
Identity and completeness
Machine tags, modules, components, accessories, change parts, tools and visible workmanship.
Safety and manual functions
Guards, stops, alarms, sensors, rotation and basic functions under the agreed test basis.
Material flow
Container transfer, filling/capping behavior, label/pack interfaces, accumulation and stop/restart response.
Documents and spares
Drawings, manuals, electrical information, parts identification and shipment packing plan.
03
Control open items and release
A FAT can identify actions without pretending every site-only condition can be proven in the workshop.
Finding
Describe the observation and the contract or test point it relates to.
Action
Name the correction, responsible party, due date and required closure evidence.
Limitation
Record what could not be tested and how it will be checked at site.
Shipment decision
Define release, conditional release or hold using the authorized project process.
Buyer questions
Questions to settle before the next project gate
Does FAT prove final plant output?
Not necessarily. Site utilities, product, integrated equipment and operating conditions may differ. The acceptance basis must state what FAT does and does not prove.
Can FAT use substitute materials?
Only when the limitations and later confirmation plan are agreed. Critical bottle, cap, label and pack interfaces may require approved materials.
Who pays for retesting?
That is a commercial term to settle in the order or change-control process, not an assumption to make during FAT.
