Of which 7.2.4.deals with ungrounded equipment. In 7.2.4.1 General (toward the end ) it says you can: sweeping of the EUT with a grounded carbon fibre brush with bleeder resistors (for example, 2 × 470 kÙ) in the grounding cable. Where can I find a carbon fiber brush I can then ground (with two 470Kohm resistors)? Would a fanned out multi-strand copper wire work just as well to dissipate the ESD charge buildup?
