Rearview Mirror Camera Specification Example for Off-Road Bikes: Premium Line
Rearview Mirror Camera Specification Example for Off-Road Bikes: Premium Line
This is a worked specification for rearview mirror camera in a premium line programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The premium line version exists because the duty cycle on off-road bikes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually reorders that did not match the approved sample.

- State the inspection level and who pays when a lot fails.

Processes involved
- laser cutting
- precision stamping
- ultrasonic cleaning
- robot welding
- powder coating
- die casting
Where this example applies
Programmes that run premium line most often specify this build for off-road bikes. Related applications include dealership service, three-wheelers, construction equipment, assembly programmes, workshop replacements.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 2.5 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the ECE R90-compliant build instead of a fresh interpretation.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 3000 pieces per line.
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
How long does sampling take?
Samples leave the factory in 7 working days, and each revision round adds about 3 days once you have seen the first piece.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
