Factory acceptance testing, SAT and site activities
Witnessed proof that equipment performs before it leaves the factory, and verified installation and handover at site.
Overview
The last chance to find problems cheaply
A defect found at the factory acceptance test costs hours to fix. The same defect found after installation costs weeks, and sometimes a production shutdown. FAT is the moment when the buyer confirms, with the supplier's equipment and engineers still available, that the product performs as specified.
QUALITAS TR witnesses FAT on behalf of buyers: reviewing the test procedure in advance, confirming instrument calibration, witnessing each test step, recording results, managing the punch list and issuing a clear acceptance recommendation.
At site we support installation inspection, site acceptance tests, commissioning support and the review of final handover documentation, providing continuity between what was tested at the factory and what is accepted in the field.

How we work
A FAT that produces a decision
Preparation determines whether a FAT is a formality or a real acceptance test.
Procedure review
Test procedure checked against the specification: test steps, acceptance criteria, instruments, duration and records.
Readiness check
Pre-FAT confirmation that the equipment is complete, internally tested and documents are available. Avoids wasted trips.
Witness
Each step witnessed, values recorded, deviations noted. Calibration certificates of test instruments verified.
Punch list
Open items categorised by whether they prevent shipment, with owners and dates.
Recommendation
FAT report with acceptance recommendation, conditions and the punch list for close-out.

Frequently asked questions
Who writes the FAT procedure?
Normally the supplier, approved by the buyer. We review it before the test and propose additions where specification requirements are not covered.
Can a FAT be witnessed remotely?
Partially. Remote video witnessing can support simple tests, but measurement verification, instrument checks and close examination need a person on site. We advise which parts can be remote.
