How should tolerances be marked before RFQ?

How should tolerances be marked before RFQ?

Use standard GD&T symbols on the 2D drawing with feature control frames for geometric tolerances and direct dimension limits for size tolerances. Include a general tolerance note for unspecified dimensions.

Specification Note: Specify the standard used (ISO, ASME, DIN) in the drawing title block.

Procurement Tips

• Use standard GD&T symbols

• Specify tolerance standard in title block

• Call out only critical functional tolerances

• Use general tolerances for non-critical features
