1.1 These methods of test cover procedures for the determination of volume and surface resistance and calculations for determination of volume and surface resistivity of solid insulating materials.
1.2 Both volume and surface resistance tests are affected by the following factors: (a) the magnitude and time of voltage application, (b) the nature and geometry of the electrodes, and ( c ) the temperature and humidity of the ambient atmosphere during conditioning and measurement. Recommendations are made for these factors.
