A factory acceptance test checklist, or FAT checklist, is a document used in the manufacturing and quality assurance process to ensure a piece of equipment meets the specific requirements necessary to perform its function. The checklist verifies that the equipment is ready for installation and reduces the risk of issues and failures.
A factory acceptance test checklist contains a set of items and criteria that must be verified during the testing process.
Here are 10 of the key elements found in an FAT checklist
- Documentation Review: Ensure completeness and accuracy of manuals, specifications and drawings.
- Functional Testing: Verify equipment’s functionality based on design documents.
- Performance Testing: Measure equipment against specified criteria.
- Safety Checks: Evaluate safety features for compliance with standards.
- Environmental Testing: Assess equipment’s reliability under varying conditions.
- Interface Testing: Check compatibility for seamless integration.
- Alarm and Error Handling: Confirm effective issue detection and response.
- Calibration and Measurement: Ensure sensor accuracy through calibration.
- Electrical Testing: Examine electrical components for compliance and safety.
- Sign-off and Approval: Obtain relevant parties’ signatures to confirm successful FAT completion.
An FAT checklist assures quality by thoroughly testing the equipment against predetermined criteria, reducing the risk of defects or operational issues post installation. It helps to identify and address issues during the testing phase, minimising equipment downtime and costly repairs. A well-documented checklist provides transparency and traceability, aiding in accountability and communication.
The most common issues found during a FAT
- Functional Failures: Equipment may not perform as intended, with issues like inaccuracies, malfunctioning parts or incorrect movements.
- Safety Concerns: Problems with safety mechanisms or compliance with safety standards can pose significant risks.
- Control System Glitches: Error in control systems, including programming flaws, can lead to erratic behaviour.
- Compatibility Problems: Interface issues, such as data transfer failures or incompatibilities, may hinder seamless integration.
