This standard is applicable to the determination of the volume resistivity of ceramic fabrics with electronic thousand-yuan devices in the range of choking temperature to 500 ° C. The test principle is to characterize the insulation performance of ceramic materials by measuring the ratio of DC electric field strength to Current density in the volumetric current direction of the sample. Usually, the resistivity of ceramic materials decreases with increasing temperature. Sample preparation includes selecting samples that meet the requirements of the standard, cleaning, drying treatment, and coating sintered silver electrodes on both planes of the sample.
