Heat Rejection Tint Specification Example for Aftermarket Retail: Off-Road Version
Heat Rejection Tint Specification Example for Aftermarket Retail: Off-Road Version
This is a worked specification for heat rejection tint in a off-road version 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 off-road version version exists because the duty cycle on aftermarket retail is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a supplier who changed material without saying so.

Example specification
| Item | Heat Rejection Tint |
|---|---|
| Application | Aftermarket Retail |
| Version | Off-Road Version |
| Base material | Nylon 66 |

| Sampling | 10 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 — Nylon 66, 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
- powder coating
- electroplating
- precision stamping
- robot welding
- CNC machining
- rubber vulcanisation
Where this example applies
Programmes that run off-road version most often specify this build for aftermarket retail. Related applications include assembly programmes, construction equipment, trailer axles, passenger cars, export programmes.
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 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.
What is the minimum order quantity?
The standard MOQ is 2000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
What testing is included?
Standard lots ship with dimensional and hardness reports. REACH documentation is issued with the shipment when your market requires it.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 2000 pieces per line.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
