Materials and methods

Test guideline

Qualifier:

according to guideline

Guideline:

other: IEC 62141-2-2

Principles of method if other than guideline:

The test cell consists of two metal electrodes that are positioned on a non-conducting (glass) base plate. The gap (length 100mm, height 10mm, width 10mm) between the electrodes is filled with the dust sample. The resistance of the dust sample is measured for a set of applied voltages (up to 2000 V DC). The electrical resistivity of the powder is calculated from the meausred resistance.
