Project Delivery
Factory Acceptance Test Guide
A factory acceptance test checks agreed machine functions before shipment using a written protocol, available samples and defined evidence. It can reveal engineering or documentation gaps while correction is still practical.
Direct answer
What this decision means for a real filling project
A factory acceptance test checks agreed machine functions before shipment using a written protocol, available samples and defined evidence. It can reveal engineering or documentation gaps while correction is still practical.
This guide is part of the Factory Readiness and Commissioning cluster. Read the hub when the project still needs a broader comparison.
Engineering inputs
Define the duty before comparing equipment
A useful proposal starts from agreed process and package information. These inputs keep suppliers from filling gaps with incompatible assumptions.
Send these details
- Approved specifications
- Test products or substitutes
- Containers caps and labels
- Target test duration
- Acceptance criteria
Require these checks
- Verify safety and functions
- Run representative formats
- Record output and quality
- Issue signed punch list and closure evidence
Line integration
Connect the choice to upstream and downstream equipment
Project delivery connects supplier engineering with the buyer's building, utilities, people and local obligations. A responsibility matrix and approved layout prevent interfaces from being discovered only during installation.
Comparison sheet
Put every supplier on the same basis
| Decision area | What to state in the RFQ | What to verify |
|---|---|---|
| Product | approved specifications | verify safety and functions |
| Package | test products or substitutes | run representative formats |
| Performance | containers caps and labels | record output and quality |
| Operation | target test duration | issue signed punch list and closure evidence |
| Project scope | Utilities, interfaces, documents, spares, packing, shipping and support | Written inclusions, exclusions and acceptance evidence |
Verification route
Move from a claim to recorded evidence
Use staged verification: document review, factory testing, shipment inspection, installation checks and site acceptance. Open items should have owners and deadlines rather than being hidden inside a general completion statement.
- Approve the duty, drawings and test conditions before fabrication is treated as final.
- Use production-intent product and packaging wherever they materially affect performance.
- Record results by format, operating condition and quality criterion rather than relying on a short edited video.
- List open items, owners and closure evidence before packing and again after site commissioning.
FAT execution
Twelve checkpoints before shipment release
- Approved specification and latest drawings are available.
- Machine identity and supplied modules match the order.
- Guards, stops, alarms and interlocks are demonstrated safely.
- Representative containers, closures and labels are used.
- Product or an agreed test medium is documented.
- All required formats and change parts are checked.
- Sustained output is recorded under agreed conditions.
- Fill, closure, label, code and pack quality are measured.
- Starvation, blocking, stop and restart behavior are observed.
- Utilities and consumable conditions are recorded.
- Manuals, drawings, backups and parts lists are reviewed.
- Every deviation has an owner, due date and closure evidence.
Buyer questions
Answers to common RFQ and acceptance questions
When is Factory Acceptance Test Guide useful?
Custom filling and packaging machines before final packing and dispatch. A short demonstration video is not equivalent to an agreed FAT with recorded criteria and open actions.
What details should be supplied before requesting a quotation?
Prepare the following project-specific information: approved specifications, test products or substitutes, containers caps and labels, target test duration, acceptance criteria. Drawings, photos and representative samples help the engineering review move from a budget assumption to a defined scope.
How should the proposed solution be checked before acceptance?
Use an agreed review or test plan to verify safety and functions, run representative formats, record output and quality, issue signed punch list and closure evidence. Record the conditions, measurements and open actions so the result can be compared with the approved specification.
