A useful FAT is a project gate, not a factory tour. The checklist should connect the approved technical specification to observable test results.
Before the test
- Confirm approved drawings and open technical actions
- Verify test products, packaging and sample quantities
- Agree the test sequence, speed basis and recording method
- Identify items that can only be completed on site
Mechanical and electrical inspection
Review guarding, access, materials, component brands, wiring, labels, utilities, lubrication points and general workmanship.
Function and recipe testing
Challenge automatic, manual and maintenance modes. Verify recipes, sensors, actuators, alarms, interlocks, counters and user permissions.
Performance testing
Run agreed products at the defined output. Record quality, reject rate, accumulation behavior, changeover and any operating restrictions.
Fault and recovery testing
Simulate blocked products, missing materials, opened guards, low air, communication loss and emergency stops. Check controlled recovery rather than only alarm display.
Document handover
Review manuals, drawings, software backups, component lists, spare parts, training material and the signed punch list before shipment release.
