The standard allows measurement uncertainty. If your caliper has an error of ±0.5 mm and the tolerance is ±2 mm, you are fine. But if the tolerance is ±1 mm, you need a more precise instrument.

This refers to the tolerance for straightness, flatness, and parallelism. While linear dimensions use letters A through D, shape and position tolerances use E through H. Class F is the second-most precise level in this category (often considered "Medium" for shape). Why Use EN ISO 13920-BF?
