-----
1/ (TMAX-TMIN) shall be interpreted as the difference in total wall thickness measured (1) along a line
through the centers of the conductors between the edge of each conductor and the nearest surface of
the core and (2) between a line tangent to the two conductors and a parallel line tangent to the
surface of the core on both sides of the conductors. The eccentricity corresponding to the larger
measured value (TMAX-TMIN) shall be reported.
