A beverage filling line FAT checklist should prove that the supplied equipment matches the approved scope and performs the agreed functions before shipment. A short machine demonstration is not enough. Useful acceptance testing records conditions, measured results, evidence, deviations, owners, and items that remain for site testing.
Write the acceptance basis before the test date
Every FAT check should trace back to an approved requirement. Freeze the equipment list, layout, product and package matrix, utilities, control narrative, safety requirements, documents, and exclusions before travel is arranged.
The International Society of Automation’s ISA-105 standards page describes structured FAT, SAT, and site integration testing for automation systems. It emphasizes planning, readiness, procedures, punch-list tracking, completion criteria, and clear roles. A beverage line protocol should apply the same discipline to its mechanical, process, packaging, and automation scope.
Confirm machine identity and contracted scope
Begin with the purchase order, technical agreement, and latest approved drawings. Check equipment names, models, quantities, major options, change parts, guards, conveyors, instruments, and supplied auxiliaries. Record machine identification and photograph the agreed reference points.
- Approved equipment and option list
- Nameplates and machine identification
- Layout and flow direction
- Accessible materials and components where contractually specified
- Guards, access doors, platforms, and service points
- Loose parts, tools, startup spares, and wear parts
- Buyer-supplied items and interface boundaries
Do not accept a verbal promise that a missing option will be added later without a controlled open-item record, owner, due date, and verification method.
Prepare representative test materials
The bottles or preforms, caps, cans or ends, labels, film, cartons, trays, adhesives, and test product determine what the FAT can prove. Materials should match the approved specification and be available in enough quantity for setup, testing, expected stops, and repeat work.
If water or another substitute replaces the commercial beverage, record the limitation. A water run may show conveying and basic filling motion, but it may not prove foaming, viscosity, thermal behavior, pulp handling, carbonation retention, cleaning, or product-specific accuracy.
Test functions before chasing maximum speed
Verify manual and automatic modes, recipe selection, normal starts and stops, alarms, interlocks, emergency stops, guard switches, starved and blocked states, and recovery after a controlled disturbance. Check communication between the filler, conveyors, labeler, packer, and other connected equipment.
Observe how the line behaves when caps run low, bottles back up, a downstream machine stops, or an emergency stop is reset. The objective is controlled behavior, not a staged run in which no disturbance occurs.
Measure good output and package quality
Define the measurement point and elapsed-time basis. Gross filler cycles can hide rejected containers, unclosed bottles, label faults, or unfinished packs. For a complete beverage production line, saleable output at the agreed downstream point is usually more useful.
| Test area | What to define | Evidence |
|---|---|---|
| Output | Container, product, run duration, included time, measurement point | Counter readings and signed calculation |
| Fill | Approved sampling and acceptance method | Recorded sample results |
| Closure | Cap, torque or seam method as applicable | Instrument record and samples |
| Label and code | Position, readability, batch data, adhesion | Sample sheet and photos |
| Secondary pack | Pattern, count, seal or carton condition | Accepted packs and inspection record |
| Stops | Cause, duration, response, and exclusion rule | Stop log and control screenshots |
Use calibrated or otherwise agreed measurement tools. State the sampling frequency and pass criteria before the run. Avoid changing the acceptance method after results are known.
Demonstrate changeover and cleaning functions
For a multi-format line, test representative bottle, cap, label, and pack changes. List the required parts, tools, recipes, adjustments, and checks. Time the full line from the last acceptable old-format unit to stable acceptable production of the new format when changeover performance is contractual.
Cleaning tests should follow the agreed scope. Review drainage, access, spray or CIP sequence, chemical compatibility, temperature or concentration monitoring where specified, and safe isolation. If product validation can occur only on site, define the SAT test while the parties are together.
Review safety, documents, and maintainability
FAT does not replace the buyer’s local risk assessment or site compliance work. It can still verify the contracted guards, emergency stops, access switches, warnings, safe motion, and supplied documentation. Record any protective function that cannot be fully tested until installation.
Reconcile manuals, drawings, electrical documents, spare-parts lists, software backups, recipes, certificates or material evidence included in the contract, and training materials. Maintenance staff should review access to filling valves, capper or seamer components, drives, sensors, conveyors, lubrication points, and electrical panels.
Control the punch list and shipment release
Give every deviation a unique number and link it to the requirement and evidence. Classify whether it blocks shipment or can close later by an agreed method. Assign the responsible party, due date, corrective action, and person authorized to verify closure.
A signed FAT report should distinguish passed items, accepted deviations, open work, retests, and site-dependent items. Shipment release is a separate decision. It should state which open points remain and what evidence is required.
Keep FAT, SAT, and commissioning separate
FAT occurs at the supplier’s facility within the equipment and utility conditions available there. SAT checks installed equipment at the buyer’s site with site utilities and interfaces. Commissioning then brings the process into controlled operation, and product validation proves the commercial process where required.
One stage does not automatically replace another. Record responsibilities for installation, alignment, utilities, site materials, training, process tuning, performance runs, product quality, and final handover.
Frequently asked questions
How long should a FAT performance run be?
There is no universal duration. It should be long enough to test the contracted requirement and expose relevant feeding, heating, accumulation, stop, and quality behavior. Agree the duration before FAT.
Who should attend the FAT?
Include people who can judge process, mechanical, electrical, quality, safety, and commercial scope. The team should have clear authority to record results and manage deviations.
Can FAT be done without commercial packaging materials?
Some mechanical functions can be checked, but the limitation must be recorded. Package-specific feeding, sealing, labeling, handling, and quality may remain unproven until suitable materials are available.
Does passing FAT authorize final acceptance?
Not necessarily. Final acceptance may depend on installation, SAT, commissioning, integrated performance, product validation, documents, training, and closure of all contractual items.
Make FAT an evidence plan
A controlled FAT reduces ambiguity before equipment leaves the factory. Send the approved specification, materials, and acceptance method when discussing a filling or packaging project with Paima. The project team can then align the test scope with the proposed line.
