Meaning
Quality verification procedures validate machine functionality and manufacturing specification compliance before equipment leaves the vendor production facility. Conducting a factory acceptance test allows the buyer to verify mechanical tolerances, sensor integration, system safety interlocks and software response against agreed procurement requirements. The boundary of this evaluation ends at the vendor plant gate and does not guarantee performance following transit and final site installation.
Protocol Execution
Standardized test procedures exercise machine axes and automated tool changers under controlled shop conditions. During a factory acceptance test, engineers record positional accuracy and sub-assembly alignment metrics. Non-conformances identified in raw material or assembly integration are documented in punch lists.
Corrective actions must occur before equipment packing and shipment release.
Handover Verification
Quality documentation packages consolidate calibration certificates and baseline performance logs into a permanent record. Completing a factory acceptance test establishes sign-off authorization for shipment milestone payments. Factory baseline measurements serve as benchmark data for subsequent installation evaluations.
Documented compliance confirms that the built machine matches purchase order specifications.
Scope Limitation
Vendor factory environments feature stabilized electrical power and controlled baseline foundations that differ from customer site conditions. Passing a factory acceptance test demonstrates manufacturing completeness but cannot account for shipping shock or facility utility variances. Foundation rigidity and localized thermal cycling remain unverified until site deployment.
Final operational sign-off depends on repeating verification tests after destination commissioning.
