An auditor tests a calibration system by following a chain: from a part's inspection record to the instrument, from the instrument to its certificate, from an out-of-tolerance certificate to its assessment, and from a key characteristic to its gauge study. Every link must be a record you can pull in minutes.
| Record | What it must show | Kept where |
|---|---|---|
| Equipment register | Every instrument, use, risk, interval, status, last known good | E01 |
| Certificates | As-found and as-left data, uncertainty, traceability, standards used, conditions | Quality drive by instrument ID |
| Inspection records | The instrument ID used for each characteristic | Travelers, inspection reports |
| Interim check records | Date, check, result, initials | At the station; scanned monthly |
| Impact assessments and the OOT log | Window, trace, evaluation, decision, notification, closure | E02 |
| MSA plan and studies | Study, result, verdict, conditions, next due | E03, E04 |
| Interval changes | The old and new interval and the reason | E01 notes |
| Laboratory approvals | Accreditation and scope; approval on the supplier list | Supplier file |
The findings we see most, and how the kit prevents them
| Finding | Usual root of it | Where the kit prevents it |
|---|---|---|
| Out-of-tolerance result with no product assessment | No trigger between the certificate and the assessment | Certificate checklist (chapter 6); E02 opened the same day |
| Instrument in use past its due date | Recall not reviewed; shutdown not planned | E01 status and Summary; weekly review |
| Instrument on the floor not on the register | Employee-owned or new tools not entered | Floor walk; register scope (chapter 5) |
| Inspection records do not identify the instrument | Record design | Required instrument ID field; quarterly trace test |
| Certificate shows no as-found data or uncertainty | Purchase order does not ask for them | Lab requirements on the order (chapter 6) |
| No evidence a gauge suits a key characteristic | Calibration taken as proof of fitness | E03 plan; E04 study |
| Capability claimed on an unproven gauge | Study order reversed | E06 setup names the gauge study |
| CMM program changed without verification | No change control on programs | Chapter 12; MSA plan line |
| Intervals never reviewed | No use of as-found history | Chapter 7; monthly review |
| Customer not told about shipped product in question | Waiting for a complete assessment | E02 Summary flags notification; chapter 9 |
