For many industrial components, the Defense Logistics Agency requires "First Article Testing" (FAT) before full-scale production begins. This process is designed to ensure that a contractor can produce a product that meets all technical and performance requirements of the contract.
FAT is usually required when the item is complex, has high reliability requirements, or is being procured from a new source. The contract will specify whether "Contractor FAT" (you test it and provide a report) or "Government FAT" (the government tests it) is required.
