Rearview Mirror Camera Specification Example for Three-Wheelers: Heavy Duty
Rearview Mirror Camera Specification Example for Three-Wheelers: Heavy Duty
This is a worked specification for rearview mirror camera in a heavy duty 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 heavy duty version exists because the duty cycle on three-wheelers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually warranty claims traced back to a single lot.

Example specification
| Item | Rearview Mirror Camera |
|---|---|
| Application | Three-Wheelers |
| Version | Heavy Duty |
| Base material | High Density Foam |
| Controlled dimensions | 5 key dimensions, recorded per lot |
| Tolerance band | ±0.05 mm |
| Finish | anodised |
| MOQ | 2,000 pieces per specification |
| Sampling | 14 working days, 5 days per revision |
| Compliance | IATF 16949 |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — High Density Foam, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.

Processes involved
- electroplating
- CNC machining
- robot welding
- die casting
- injection moulding
- gravity casting
Where this example applies
Programmes that run heavy duty most often specify this build for three-wheelers. Related applications include aftermarket retail, utility trailers, delivery vans, fleet maintenance, racing teams.
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
What testing is included?
Standard lots ship with dimensional and hardness reports. IATF 16949 documentation is issued with the shipment when your market requires it.
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.
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
How long does sampling take?
Samples leave the factory in 14 working days, and each revision round adds about 5 days once you have seen the first piece.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
