Clip-On Mirror Replacement Specification Example for Emergency Vehicles: Adjustable Type
Clip-On Mirror Replacement Specification Example for Emergency Vehicles: Adjustable Type
This is a worked specification for clip-on mirror replacement in a adjustable type 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 adjustable type version exists because the duty cycle on emergency vehicles 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 | Clip-On Mirror Replacement |
|---|---|
| Application | Emergency Vehicles |
| Version | Adjustable Type |
| Base material | Tempered Glass |
| Controlled dimensions | 5 key dimensions, recorded per lot |

| Finish | powder coated |
| MOQ | 2,000 pieces per specification |
| Sampling | 7 working days, 3 days per revision |
| Compliance | REACH |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Tempered Glass, 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
- gravity casting
- assembly line testing
- electroplating
- rubber vulcanisation
- sintering
- precision stamping
Where this example applies
Programmes that run adjustable type most often specify this build for emergency vehicles. Related applications include aftermarket retail, trailer axles, dealership service, rental motorcycles, three-wheelers.
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. REACH documentation is issued with the shipment when your market requires it.
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 7 working days, and each revision round adds about 3 days once you have seen the first piece.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the REACH-compliant build instead of a fresh interpretation.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
