This part of IEC 62631 describes test methods for the determination of permittivity and dissipation factor properties of solid insulating materials (AC methods from 0,1 Hz up to 10 MHz).<\/p>\n

\n

NOTE This part of the standard mainly considers measuring setups with guard-electrodes.<\/p>\n<\/blockquote>\n
