When a sample or prototype is available, approval should cover more than general appearance. Buyers can use the sample to confirm the details that will become the production reference.

These may include:

Overall dimensions
Roof movement
Profile appearance
Surface finish
Connection details
Accessories
Color reference
Packaging requirements
A specific approval record gives both buyer and manufacturer the same reference for the next production stage.
