Computed ISO 286 fit outcome must match the intended fit type
Rule Card¶
| Field | Value |
|---|---|
| Pack | F_OVERLAY — Industry Overlay and Compliance |
| Title | Computed ISO 286 fit outcome must match the intended fit type |
| Severity | critical |
| Check logic | Hybrid |
| Applies to | Compliance overlay |
| Inputs required | hole_features |
| Fix template | Adjust tolerance classes or nominal sizes (e.g., change from m6 to k6) until min/max clearance meets the intended functional fit; update drawing callouts. |
Short Description¶
Validates that the selected ISO 286 tolerance classes produce the intended clearance/transition/interference range for each tagged mating pair.
When It Applies¶
This rule runs only when an overlay activates F_OVERLAY. It targets Compliance overlay.
