Hello all

IPC Testmethod Number 2.3.25 (Date 2/88)  Resistivity of Solvent Extract
seems to have an error. 
Nr. 2.3.25 requires 100ml of wash solutions for each 250mm2 of the board
MIL-STD-2000A requires 1.55ml for each cm2 (also MIL-P-28809 10ml/in2)

i think IPC should reqire 100ml at 6451.6mm2
Is this correct?
