Anti Theft Lock Specification Example for City Buses: Load Rated Version
Anti Theft Lock Specification Example for City Buses: Load Rated Version
This is a worked specification for anti theft lock 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 city buses 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
| Item | Anti Theft Lock |
|---|---|
| Application | City Buses |
| Version | Load Rated Version |
| Base material | High Density Foam |
| Controlled dimensions | 6 key dimensions, recorded per lot |
| Tolerance band | ±0.1 mm |
| Finish | zinc plated |
| MOQ | 2,000 pieces per specification |
| Sampling | 7 working days, 5 days per revision |
| Compliance | ECE R90 |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — High Density Foam, 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
- heat treatment
- shot blasting
- gravity casting
- powder coating
- cold forging
- CNC machining
Where this example applies
Programmes that run load rated version most often specify this build for city buses. Related applications include city buses, export programmes, courier fleets, aftermarket retail, long-haul trucks.
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
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.
What testing is included?
Standard lots ship with dimensional and hardness reports. ECE R90 documentation is issued with the shipment when your market requires it.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 2000 pieces per line.
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.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
