Mobile Phone Repair Tools Specification Example for City Buses: High Performance

This is a worked specification for mobile phone repair tools in a high performance 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 high performance version exists because the duty cycle on city buses is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a fitment that looked right on paper and failed on the bench.

How the example is built up

  2. Fix the base material in writing — Sintered Metal, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Where this example applies

Programmes that run high performance most often specify this build for city buses. Related applications include municipal fleets, light trucks, long-haul trucks, off-road bikes, trailer axles.

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

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.

Can the specification be held on file?

Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the CCC-compliant build instead of a fresh interpretation.

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.

How long does sampling take?

Samples leave the factory in 7 working days, and each revision round adds about 5 days once you have seen the first piece.

Send the specification you are working to and we will confirm what we can match, what we would change and why.
