Automotive Air Conditioning Specification Example for Agricultural Trailers: Load Rated Version
Automotive Air Conditioning Specification Example for Agricultural Trailers: Load Rated Version
This is a worked specification for automotive air conditioning in a load rated 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 load rated version version exists because the duty cycle on agricultural trailers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually inconsistent hardness between lots.

Example specification
| Item | Automotive Air Conditioning |
|---|---|
| Application | Agricultural Trailers |
| Version | Load Rated Version |
| Base material | Semi-Metallic Compound |
| Controlled dimensions | 3 key dimensions, recorded per lot |
| Tolerance band | ±0.05 mm |
| Finish | powder coated |
| MOQ | 200 pieces per specification |
| Sampling | 14 working days, 3 days per revision |
| Compliance | ISO/TS 16949 |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Semi-Metallic Compound, 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
- surface grinding
- precision stamping
- powder coating
- heat treatment
- anodising
- injection moulding
Where this example applies
Programmes that run load rated version most often specify this build for agricultural trailers. Related applications include courier fleets, off-road bikes, long-haul trucks, utility trailers, construction equipment.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 1.5 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
How long does sampling take?
Samples leave the factory in 14 working days, and each revision round adds about 3 days once you have seen the first piece.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.
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 testing is included?
Standard lots ship with dimensional and hardness reports. ISO/TS 16949 documentation is issued with the shipment when your market requires it.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
