FAT, SAT and pressure checks
Carbonated filling pressure safety and acceptance testing.
Plan safe, measurable checks for counter-pressure and isobaric filling projects before the equipment is signed off.
Pressure and acceptance
Agree pressure checks and sign-off criteria before installation.
Carbonated filling uses pressure to control foam and protect CO₂. That makes the acceptance plan more important than it would be for a simple still-liquid filler. The project should define what needs to be checked during FAT, SAT or sample trials, and which measurements will be reviewed only when the buyer has suitable test equipment.
The final pressure settings should be confirmed from the machine documentation, the drink, product temperature and package. This page does not publish generic pressure ranges because unsupported numbers can lead to an unsafe or unsuitable specification. The right approach is to agree the product, container, closure, purge route and acceptance checks for the real application.
| Before FAT | Confirm product or surrogate product, container samples, closure samples, utilities, operator access and test aims. |
|---|---|
| During FAT/SAT | Check filling sequence, purge or pressurisation, foam behaviour, fill level, closure transfer, cleaning access and safe operator procedures. |
| Quality evidence | Record filled appearance, leakage checks, closure quality and, where relevant, dissolved oxygen, TPO or carbonation measurements using a consistent method. |
| After sign-off | Keep the agreed setup data, sample results, changeover notes and operator training points with the project file. |
Acceptance checklist
Information that makes a pressure-controlled trial useful.
Product evidence
Drink type, carbonation target, product temperature, viscosity if relevant, foam tendency and any oxygen sensitivity.
Package evidence
Container drawing or sample, fill volume, neck or can-end specification, closure samples and finished-pack appearance requirements.
Line evidence
Required output, operator handling, utilities, changeover formats, downstream closure route and available floor space.
Buyer questions
Common questions before specifying this part of the line.
Should pressure ranges be chosen from a website?
No. Final pressure settings should be confirmed from the machine documentation, the drink, product temperature, package and trial evidence.
What should be checked during FAT or SAT?
Typical checks include the filling sequence, purge or pressurisation, fill level, foam behaviour, closure transfer, operator access, utilities and cleaning access.
Do all drinks need DO and TPO checks?
No. DO and TPO checks are most relevant when the buyer has oxygen-sensitive products and a reliable measurement method.
Can this be used for both bottles and cans?
Yes. The acceptance structure applies to both bottle and can projects, but the closure checks differ between crowning, capping and seaming.
Project review
Send the product, pack and line details.
Lancing can review the carbonated drink, container, closure, utilities and target output before recommending a filling route.
