This document specifies the test method for the determination of total electrical conductivity of conductive fine ceramics by the DC (direct current) four-terminal method. The test method applies to conductive fine ceramics which have an ionic transference number of 0,01 or less. The applicable conductivity range is from 1 S cm?1<\/sup> to 1 000 S cm?1<\/sup> and the temperature range is up to 1 000 \u00b0C. The values expressed in the test method are in accordance with the International System of Units (SI).<\/p>\n

This document is intended for industrial product quality control and material development of conductive fine ceramics used in electrodes, e.g. fuel cells, batteries and water electrolysis.<\/p>\n
