Paper Machinery Factory Acceptance Test FAQ
Data: ISO publishes machinery safety and quality management standards, including the ISO 9001 family and the ISO 12100 machinery risk assessment framework, which define how equipment conformity and process control are documented.
Judgment: Anchor the acceptance clause to a published standard rather than a verbal expectation, because conformity vocabulary gives the buyer a defensible position when a machine underperforms after shipment.

Data: UL Solutions provides product safety certification and testing services across industrial equipment categories, documenting that a product has been evaluated against defined safety requirements.
Judgment: Ask what was evaluated, by whom and to which standard rather than accepting a logo, because the scope of a safety evaluation matters as much as its existence at installation.

Data: The U.S. Occupational Safety and Health Administration maintains machine guarding requirements and guidance describing how moving machine parts must be protected to prevent operator injury.
Judgment: Treat guarding as a verifiable test item with a photographic record, because retrofitting interlocked guarding after installation costs more than confirming it before shipment.

What is a factory acceptance test for paper machinery?
A factory acceptance test is a witnessed run of the machine at the supplier's works before shipment, performed against criteria written into the purchase contract. It records output, waste, stoppage time and quality measurements on the buyer's own board or cup stock, and it produces a signed report plus a punch list. Its purpose is to prove the machine meets the agreed specification while the balance payment still gives the buyer real leverage. A test without recorded numbers is a demonstration, not an acceptance.
What should be fixed before paying a machinery deposit?
Fix the test protocol before the deposit. That means the material to be run, the duration and speed of the run, which measurements are taken, who signs, what counts as a pass, and what remedy applies if the test fails. Also fix the documentation package that ships with the machine, including drawings, manuals and conformity papers. A protocol agreed on the day of the visit is a conversation; a protocol written into the contract is an enforceable remedy with payment staged against it.
Which documents should a buyer collect at FAT?
Collect the signed FAT report with raw data, the conformity documentation required by the destination market, electrical and pneumatic drawings with revision numbers, a spare parts list with part numbers, the maintenance schedule, and operation and maintenance manuals in the buyer's language. Where pressure vessels or safety components apply, request the relevant component test certificates. Keep the whole set as one file per machine, because a later warranty claim is argued from what the acceptance test recorded rather than from memory.
How long should the running test last?
Long enough to expose thermal drift and wear-in, which is typically a sustained run rather than a short demonstration. A practical structure samples at start-up, early steady state, mid run and late run, so dimensional drift and rising reject rates become visible. Buyers should bring their own stopwatch and measuring instruments and run on their own material, because board stiffness, moisture and coating change forming behaviour. A run that holds tolerance for ten minutes and drifts by minute forty is exactly what a short test hides.
What safety items must the test demonstrate?
Demonstrate fixed guarding that cannot be removed by hand, interlocked access doors, emergency stops verified from each operator position, deliberate reset behaviour, and shielded hot surfaces and pinch points. The sequence matters: open the guard while the machine runs, confirm motion stops, then confirm it does not restart on closing alone. A guard that is present but not interlocked satisfies a photograph and fails a workplace inspection. Photograph nameplates, guard positions and emergency stop layout as part of the same record.
How does a punch list protect the balance payment?
A punch list converts observations into dated obligations. Each item should state the defect numerically, the threshold that counts as closure, the corrective action, a named owner and a date, and the evidence required to close it. Hold the final instalment until the list closes on evidence rather than promises, and refuse photographs as substitutes for a retest where the defect is performance-based. Carry the same open-item list forward to site acceptance so commissioning starts from recorded issues rather than a blank page.
