What is a Factory Acceptance Test Checklist?

A factory acceptance test checklist is a comprehensive document that outlines the criteria, procedures, and requirements to assess and verify equipment and system quality, functionality, and conformity. Quality managers, design engineers, operators, and maintenance personnel use this as a tool to test and ensure that newly produced equipment works according to design specifications before installation and operation.

Why Use a Factory Acceptance Test Checklist?

Overlooked equipment discrepancies can lead to installation problems on site, which can wreak havoc on a project schedule. Prior to shipment, quality managers should resolve nonconformity at the factory so that the clients’ new processing lines are up and ready to go on time.

When FATs are conducted with the help of checklists, the following issues can be proactively identified and avoided:

• Poor Machine Quality or Craftsmanship

• Nonconformity to Regulatory or Sanitary Specifications, especially for pharmaceutical or nutraceutical manufacturing (e.g., American Society of Mechanical Engineers (ASME), International Electrotechnical Commission (IEC))

• Lack of Appropriate Machine Guarding and Labels (e.g., Lock Out Tag Out (LOTO) labels and procedures, compliance with Occupational Health & Safety Administration (OSHA) standards)

• Lower than Expected Throughput

Hence, using a factory acceptance test checklist template can reduce costly project delays by ensuring the completion of factory acceptance test and its protocols—such as standard work procedures, certificates of compliance, and welding process qualifications, and implementing the proper factory acceptance test procedure.

What Should be Included in a Factory Acceptance Test Checklist?

A good factory acceptance test checklist should enable quality managers to make sure that no aspects are overlooked when it comes to performing factory acceptance tests. A comprehensive FAT checklist should include the following:

1. Documentation Review

• Verify technical specifications, design drawings, and manuals.

• Ensure calibration certificates and material certificates are available.

• Confirm compliance with regulatory standards and customer requirements.

• Check the bill of materials against delivered components.

2. Pre-Test Preparation

• Ensure test procedures and acceptance criteria are clearly defined.

• Confirm availability of required tools, instruments, and test rigs.

• Assign responsibilities to test personnel.

• Review risk assessments and safety protocols before starting.

3. Mechanical & Structural Inspection

• Verify equipment dimensions and physical condition.

• Check welding, joints, and finishes for defects.

• Ensure proper installation of moving parts, bearings, and fasteners.

• Confirm correct labeling, tags, and nameplates.

4. Electrical & Control Systems

• Inspect wiring, grounding, and connections.

• Test protective devices (fuses, circuit breakers, relays).

• Verify control panels and interfaces are functional.

• Confirm software/firmware versions match the specification.

5. Functional Testing

• Operate equipment under different modes (manual, automatic).

• Test alarms, interlocks, and emergency stops.

• Verify startup, shutdown, and restart sequences.

• Simulate fault conditions where feasible.

6. Safety & Compliance

• Check compliance with OSHA, CE, ISO, or other relevant standards.

• Inspect safety guards, light curtains, and lockout/tagout devices.

• Verify safety signage is visible and accurate.

• Review hazardous material handling protocols (if applicable).

7. Performance & Reliability Testing

• Run performance tests against agreed KPIs.

• Measure vibration, noise levels, and thermal behavior.

• Test endurance and repeatability under simulated load.

• Confirm energy efficiency or environmental compliance metrics.

8. System Integration & Connectivity

• Verify interfaces with upstream/downstream systems.

• Test communication protocols

• Check integration with MES, ERP, or SCADA systems.

• Confirm data logging and reporting functions work correctly.

9. Documentation & Reporting

• Record all test results and deviations.

• Ensure calibration records and certificates are attached.

• Include photos/videos of critical test steps where useful.

• Compile the FAT report in the agreed template.

10. Post-Test Review

• Conduct a debrief session with stakeholders.

• Document corrective actions and retest results if needed.

• Prepare recommendations for commissioning and site acceptance test (SAT).

• Store all records in a traceable, accessible system.

How to Create an Effective Factory Acceptance Test Checklist

An effective factory acceptance test checklist should be thorough, traceable, and practical. Additionally, it should:

• Be grounded in technical documentation

• Provide a detailed test plan and acceptance criteria

• Include specific tests such as visual and physical inspection, functional testing, safety and failure scenarios, and compliance checks

• Have structured documentation, reporting, and formatting

• Align expectations between vendors, customers, and inspectors

Perform Factory Acceptance Test Using a Checklist

Conducting a factory acceptance test using a checklist is a critical step to ensure that equipment or systems meet specified requirements and quality standards before they are delivered to the customer. Hence, properly following a structured process is essential to achieving the desired outcomes and avoiding potential issues.

Follow these steps to effectively carry out a FAT with the help of a checklist:

1. Prepare for the FAT testing

Ensure that all parties involved, including the customer and the manufacturer, have reviewed and agreed upon the FAT checklist. Also, verify that the testing environment is set up and that all necessary documentation, tools, and personnel are in place.

2. Perform the tests

Test the equipment or system’s various functions, performance parameters, and safety measures. Make sure to document the results of each test, including any deviations or discrepancies from the checklist.

3. Document real-time observation

Designated individuals, including customers and third-party inspectors, must observe and document their real-time observations during the tests using the checklist. They can verify that these are conducted impartially and that the equipment meets the acceptance criteria.

4. Address deviations and issues

If the equipment fails to meet any of the acceptance criteria or if discrepancies are found during testing, develop a plan to address them. The manufacturer is responsible for rectifying the problems and retesting the equipment until it complies with the requirements specified in the checklist.

5. Finalize documentation and obtain approval

Once all tests have been successfully completed, and any issues resolved, finalize the documentation of the FAT results. This should include a summary of the tests, deviations, resolutions, and any relevant observations. Make sure to obtain approval from all parties involved before proceeding with the shipment of the equipment or system.

FAT Report Example

A factory acceptance test report serves as a crucial documentation tool, summarizing the results and findings of the FAT and helping you understand how it supports the assurance of a successful project outcome.
