Onboard Diagnostic Tools Specification Example for Workshop Replacements: Lightweight Version
Onboard Diagnostic Tools Specification Example for Workshop Replacements: Lightweight Version
This is a worked specification for onboard diagnostic tools in a lightweight 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 lightweight version version exists because the duty cycle on workshop replacements 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 — Cast Iron, 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
- assembly line testing
- die casting
- powder coating
- surface grinding
- electroplating
- precision stamping
Where this example applies
Programmes that run lightweight version most often specify this build for workshop replacements. Related applications include racing teams, trailer axles, long-haul trucks, scooter fleets, municipal fleets.
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.
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
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.
What is the minimum order quantity?
The standard MOQ is 3000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
