Question

Quizplus · Accepted Answer

The Answer is Thwe following conditions apply:
1. The tolerance zone is the space between two parallel planes
2. The tolerance zone may be oriented to best fit the high and low points of the surface
3. All surface elements of the controlled surface must be within this zone
4. The distance between the parallel planes is equal to the flatness tolerance value
5. The tolerance zone extends across the length and width of the surface
