Which statement is NOT part of a standard feature control frame?

• A. Material specification
• B. Geometric characteristic symbol
• C. Tolerance value/modifier
• D. Datum references

Answer: (A)

A standard feature control frame conveys how a geometric characteristic must be controlled, including the geometric symbol, the tolerance value (with any modifier), and the datum references that establish the controlling datums. It does not include material specification; material details are given in notes or in the title block/BOM, not inside the feature control frame. So the statement about material specification does not belong in the frame, which is why it’s the correct choice. The frame always includes the geometric symbol, the tolerance value/modifier, and the datum references.
