12V Electric Car Fridge Specification Example for Construction Equipment: Adjustable Type
12V Electric Car Fridge Specification Example for Construction Equipment: Adjustable Type
This is a worked specification for 12v electric car fridge 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 construction equipment is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a specification nobody had written down.

How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Stainless Steel, 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
- cold forging
- gravity casting
- die casting
- injection moulding
- sintering
- heat treatment
Where this example applies
Programmes that run adjustable type most often specify this build for construction equipment. Related applications include assembly programmes, racing teams, workshop replacements, scooter fleets, off-road bikes.
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
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.
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. RoHS documentation is issued with the shipment when your market requires it.
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 3 days once you have seen the first piece.
