Factory Acceptance Testing (FAT)

Long term performance and reliability can only be ensured when equipment meets its designed operating specification. Xi can assist in the measurement and analysis of vibration and displacement necessary to benchmark a machine’s performance against operating standards.

Factory Acceptance Testing or FAT testing is an important final stage in commissioning of a machine either before it leaves the factory or when major work or overhaul has taken place.  It is important that vibration and displacement levels fall within the prescribed level or standards for that class of machinery.  Knowing the equipment performs as it should in the factory may indicate that later faults are due to installation problems rather than with the newly installed machine.  Typically, the dynamics of a machine will be assessed using vibration acceleration, velocity or displacement.  Xi can assist in all areas of the machine dynamics including the assessment of casing vibration, reviewing frequencies and amplitudes and rotational shaft analysis; orbit analysis and torsional vibration.
