Portable Vehicle Cooler Specification Example for Assembly Programmes: Premium Line
Portable Vehicle Cooler Specification Example for Assembly Programmes: Premium Line
This is a worked specification for portable vehicle cooler 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 assembly programmes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually inconsistent hardness between lots.

Processes involved
- assembly line testing
- die casting
- shot blasting
- anodising
- ultrasonic cleaning
- laser cutting
Where this example applies
Programmes that run premium line most often specify this build for assembly programmes. Related applications include off-road bikes, scooter fleets, workshop replacements, export programmes, three-wheelers.
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
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.
What testing is included?
Standard lots ship with dimensional and hardness reports. ISO 9001 documentation is issued with the shipment when your market requires it.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the ISO 9001-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 2000 pieces per line.
