# PSW, Acceptance Criteria and Approval Status

## PSW content

| Section | Fields |
|---------|--------|
| Part information | Part number and name, drawing number and revision, engineering change level and date, safety / government regulation flag, PO number, weight (kg, 4 decimals), checking aid number and change level |
| Organization | Supplier name, code, manufacturing site address |
| Material reporting | IMDS or other customer format, submission ID; substances of concern declaration |
| Reason for submission | Initial, engineering change, tooling, correction of discrepancy, material/sub-supplier change, process change, inactive tooling, other |
| Submission level | 1-5 |
| Results | Dimensional, material/functional, appearance, statistical process package: meets all requirements yes/no |
| Declaration | Samples representative of parts made with production tooling and processes at the quoted rate; signed by an authorized person with title, phone, date |
| Customer use only | Approval disposition and signature |

Never sign "meets all requirements" with a known nonconformity: submit with a documented deviation or interim
approval request instead.

## Initial process study acceptance (special characteristics)

| Result (stable process) | Interpretation |
|-------------------------|----------------|
| Index > 1.67 | Meets acceptance |
| 1.33 <= index <= 1.67 | May be acceptable; contact the customer and review |
| Index < 1.33 | Does not meet acceptance; contact the customer; 100% inspection and a corrective action plan |

Use Ppk for initial studies when data are from a short run; Cpk when the process is stable over time. At least
100 readings in 25 or more subgroups (or as the customer agrees). Unstable processes, one-sided specifications
or non-normal data: agree the approach with the customer before submission.

## Customer approval status

| Status | Meaning | Supplier action |
|--------|---------|-----------------|
| Approved | Part meets all requirements | Ship production quantities |
| Interim approval | Limited time or quantity approval | Ship within the limits; close the action plan; resubmit |
| Rejected | Does not meet requirements | Correct and resubmit; no production shipments |

## Dimensional results

Ballooned drawing, every characteristic with specification, measured values per sample (commonly 5 parts per
cavity, mould, die, line or process stream), OK/NOK, measuring equipment. Any NOK result blocks "meets all
requirements" unless covered by an approved deviation.
