FACTORY ACCEPTANCE TESTING (FAT) WITNESS
Independent on-site and remote witnessing of functional, performance, pressure, and routine factory tests prior to equipment release.
- Hydrotest
- Performance
- Routine & Type Tests

The Factory Acceptance Test (FAT) is your final technical gate before equipment leaves the vendor's premises. Representing your interests on the test bay, QTEK engineers verify test setup calibration, witness live test execution per approved FAT procedures, and ensure all anomalies or punch items are recorded and resolved.
What QTEK verifies on every assignment
- 01Pre-FAT readiness check: verification of approved FAT procedure, ITP status, and valid calibration certificates for all test instruments
- 02Pressure & tightness testing: hydrostatic shell test, pneumatic test, fugitive emission, and high-pressure gas seat tests
- 03Rotating mechanical FAT: NPSH, head-capacity curve, mechanical run test (4-hour continuous), vibration, bearing temperature, and noise level measurement
- 04Electrical & automation FAT: routine tests, temperature-rise review, load bank testing, and integrated PLC/SCADA simulation
- 05Issuance of on-the-spot Punch Lists (Category A/B) and Conditional/Unconditional Release Certificates (IRN)
- 06Remote FAT coordination (live high-definition streaming supervision when travel is restricted)
