Integrated Bumper Specification Example for Municipal Fleets: Adjustable Type
Integrated Bumper Specification Example for Municipal Fleets: Adjustable Type
This is a worked specification for integrated bumper 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 municipal fleets 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.
Example specification

How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Bronze, 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
- anodising
- assembly line testing
- die casting
- sintering
- ultrasonic cleaning
- powder coating
Where this example applies
Programmes that run adjustable type most often specify this build for municipal fleets. Related applications include agricultural trailers, trailer axles, export programmes, long-haul trucks, racing teams.
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
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.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the E-mark-compliant build instead of a fresh interpretation.
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.
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.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
