SPECIFIC POWDER RESISTIVITY
[EN 61241; IEC 93]
The specific powder resistivity is the specific electrical resistance in Ohm·m.
It is determined as the average value from five measurements carried out in a cell with two electrodes of 20 cm² cross section.
The bulk resistivity is a relevant parameter for the assessment of the hazard of charge accumulation.
Objects having a resistivity > 108 Ohm·m are likely to show charge accumulation, objects with > 1010 Ohm·m are always subject to charge accumulation.
