Onboard Diagnostic Tools Specification Example for Municipal Fleets: Load Rated Version
Onboard Diagnostic Tools Specification Example for Municipal Fleets: Load Rated Version
This is a worked specification for onboard diagnostic tools 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 municipal fleets 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.

- precision stamping
Where this example applies
Programmes that run load rated version most often specify this build for municipal fleets. Related applications include light trucks, rental motorcycles, city buses, delivery vans, boat trailers.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 4.0 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 2000 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.
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.
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.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
