The description of the allowable variation between a feature and its basic dimensions is called what?

• A. A color property
• B. A calibration chart
• C. A description of the allowable variation between a feature and its basic dimensions
• D. A device to modify color

Answer: (C)

Tolerance describes the allowable variation between a feature and its basic dimensions. In design and manufacturing, a basic dimension is an exact value used to define the true size or location of a feature. The tolerance establishes how far the actual feature may deviate from that exact value and still be acceptable. For example, a hole specified as 20.00 mm with a tolerance of ±0.10 mm can range from 19.90 to 20.10 mm and still pass inspection. This concept is essential for ensuring parts fit and function together consistently, even with minor manufacturing variations. The other options relate to color or calibration, not dimensional limits.
