Which term is used to describe the range of acceptable variation in a designated measurement?

Explanation:
Tolerances describe the range of acceptable variation in a designated measurement. In practice, you have a target or nominal value for a dimension, and the tolerance specifies how far the actual size may deviate while still meeting the specification. It’s often shown as a plus/minus amount or as explicit upper and lower limits. For example, a component specified as 25.00 mm with a tolerance of +0.03 / -0.02 may vary from 24.98 mm to 25.03 mm and still be acceptable. This concept lets manufacturing accommodate natural process variation while ensuring parts still fit and function together. Other terms don’t describe this range of allowable variation. Market grades refer to overall quality levels, not how much a single measurement can vary. A Qualified Products List (QPL) is a list of pre-approved items for use, not the allowable dimensional variation. The remaining term isn’t a standard descriptor for measurement tolerance in this context.
