Designing a hose production batch record

Technical explanation

In hose assembly, component and process traceability provides data for failure or change investigations. The manufacturer's safety and maintenance approach supports correct identification of the product and preservation of records. The batch model proposed here links the hose batch, fitting/ferrule batches, drawing revision and production inspection. Not every product made on the same date must automatically be treated as the same technical batch; the company's batch-forming rule should be written down.

How to evaluate it in practice

In the batch record, keep the order, product revision, length, quantity, A/B ends and the component batches used. When a component or instruction changes, apply a clear rule on whether to continue with the current batch. Link individual inspection results to the identification of the relevant physical hose. In a recall investigation, it should be possible to query which assemblies used the same component. If records are updated later, the previous information and the reason for the change must be preserved; documentation gaps must not be filled with estimated data.

Frequently asked questions

Does a batch number mean giving all hoses the same serial number?

No. A batch identifies a common production group, while an individual serial number identifies the physical unit.
