A calibration target mounted on a carbon fiber carrier is an assembly. The target pattern, its substrate, attachment and support condition all belong in the definition. A flat carrier inspection alone does not establish the accuracy of the complete calibration artifact.
State whether the controlled surface is the carbon carrier, a bonded target plate or another supplied item. Identify the pattern source and its required documentation. Keep the artwork and the mechanical drawing connected, but do not treat a printed image as a certified dimensional reference without supporting evidence.
Review the attachment and support
Show how the target is located, attached and held in the working setup. Adhesive layers, fasteners and supports can affect the assembled condition. Include the relevant environment and handling requirements where these are part of the intended use. A material label such as “low expansion” is not an assembly accuracy specification.
Define the delivered evidence
The order should distinguish a mechanical carrier from a complete, characterized target assembly. If an inspection or calibration is required, agree its scope and the identified configuration before production. Preserve that configuration with the result, including any detachable target or support. Later replacement of the pattern substrate should trigger a review of which earlier evidence still applies.
