Select standards by the work they govern: design, bare-board performance, soldering process or workmanship acceptance. Then identify revisions, classes and applicable addenda. A general reference to IPC does not define a complete purchase requirement.
Start with these questions
- Which document applies to each delivered item?
- Are revisions and exceptions stated consistently?
- What evidence must accompany the finished order?

What to keep in the project record
Use controlled copies of the actual standards for acceptance. Keep personnel training, supplier certifications and product conformity evidence distinct.
