Keep the replacement definition with the spare-parts request

A worn sample, an old drawing and an approved replacement drawing answer different questions. State which evidence you have.

The item
Machine and part references, sample condition and available photographs.
The definition
Drawing revision, material and dimensions already approved; mark unknowns separately.
The order
Quantity, destination, receiving deadline and the person responsible for technical release.

Measurement, drawing work, product checks and replacement approval need named responsibilities and an agreed quotation scope.

  • Supply a drawing, sample or measured photographs.
  • Confirm the material and the critical tolerances.
  • Review the first article against the agreed specification.
