2017年9月18日 · Concentricity is considered the “circular” form of GD&T symmetry. Both tolerances measure derived median points compared to a datum plane/axis and are notoriously difficult to measure. Runout is a combination control that can indirectly control concentricity and circularity simultaneously. e.g.

GD&T Tolerance Zone: Concentricity is a 3-Dimensional cylindrical tolerance zone that is defined by a datum axis where all the derived median points of a referenced cylindrical feature must fall within.
Practical GD&T: Concentricity Measurement - Basic Concepts
Concentricity is no longer a universal symbol, as will be discussed below. The symbol for the concentricity control is the same in both the current ISO and former ASME standards; two concentric circles along with, at a minimum, a value for the tolerance, and a reference datum.
