A pre-production sample is produced before the main run using the intended design, materials, components, artwork and manufacturing method. Approval sets the reference for production.
The operating decision
Resolve every known deviation before approval or document it explicitly. Mark the approved unit and control the matching digital records.
Evidence to retain
Store the signed specification, sample identifier, photos, measurements, tests, approval date and authorized approvers.
