Is the conductivity of the floor in ohms / sq cm known? That would help determine whether it is hazardous given electrical equipment is present. IMHO, the difference between dissipative and conductive is semantics, but perhaps there is a range for each, e.g. dissipative is > 10k per sq cm and conductive is between 100 and 10k ohms per square cm.

Hello Technet, a quick question...  For a clean room application
(microelectronics assembly), which is more appropriate, a conductive floor
or a dissipative floor (and why)?
