A product specification sheet defines the measurable, functional, material, packaging and labeling requirements a supplier must meet. It should be controlled by revision and linked to the purchase.
The operating decision
Use clear units, tolerances, test methods, drawings and approved references. Mark mandatory requirements separately from preferences.
What to keep
Retain the approved revision, change history, authorizations, supplier acknowledgment and purchase orders that used it.

| Evidence | Retain the approved revision, change history, authorizations, supplier acknowledgment and purchase orders that used it. |
