2. A measured value or physical property of a material, manufactured object, system, or service,
3. Other measured values (such as temperature, humidity, etc.).
4. In engineering and safety, a physical distance or space (tolerance), as in a truck (lorry), train or
boat under a bridge as well as a train in a tunnel (see structure gauge and loading gauge).
5. In mechanical engineering the space between a bolt and a nut or a hole, etc..
Example: Tolerances are specified to allow reasonable leeway for imperfections and inherent
variability without compromising performance
