I have always read it as that way, in the Z direction, I could use the internal spacing from column B1.  If I'm reading it wrong then I'd like to know also.

Fellow TechNetters:

   I am requesting clarification on the above stated document section 6.3 Electrical Clearance.   The minimum spacing between conductors, between conductive patterns, layer to layer conductive spaces (z=axis), and between conductive materials (such as conductive markings or mounting hardware) and conductors shall be in accordance with Table 6-1, and defined on the master drawing"."

Does this implies that the spacing is also true in the vertical, z=axis, direction as measured in a typical cross section.

Victor,
