a. Except in the case specified in 6.3.2c, floating conductive parts may be used if they have an area less than 1 cm2 and have a total capacitance less than 10 pF with respect to the structure.
NOTE This is to limit the energy available to discharge.
b. The configuration shall be such that energy involved in any possible discharge is less than one corresponding to a discharge of a capacitance of 10 pF under 6 × 103 V.
c. In case of multiple elements (in which case the empirical rule in 6.3.2a does not apply), tests shall be performed.
NOTE 1 Examples are patched antenna and solar arrays are multiple elements.
NOTE 2 See 6.3.1d NOTE for definition of a multi-conductor structures.
