Factory Acceptance Testing Procedure Documentation
Factory acceptance testing procedures organize the inspection and testing of equipment or systems before they leave the supplier or manufacturing facility.
We prepare FAT documentation from equipment specifications, purchase requirements, drawings, test plans, supplier information, and approved acceptance criteria.
Factory Acceptance Testing Procedure Writing
Consistent Pre-Delivery Testing and Review
A factory acceptance testing procedure provides a documented sequence for evaluating equipment, machinery, panels, software, or integrated systems before delivery.
We structure the procedure around test preparation, inspection points, functional demonstrations, results, defects, and authorization to proceed.
The document can be adapted to manufacturing, industrial equipment, automation, electrical systems, software, and engineered packages.

Our Process
How We Develop FAT Procedures
1. Review the equipment package
We examine specifications, drawings, supplier documents, test plans, and purchase requirements.
2. Establish the FAT scope
We identify the components, functions, interfaces, and inspections to be performed at the factory.
3. Organize the test sequence
We arrange preparation, visual checks, functional demonstrations, measurements, and evidence collection.
4. Define results and defects
We document expected outcomes, failure handling, retesting, and outstanding item tracking.
5. Prepare the review draft
We create the procedure for technical review by the supplier, customer, or project team.
6. Finalize the FAT document
We incorporate approved comments and organize sign-off, revision, and recordkeeping sections.
