精细陶瓷（高级陶瓷、高级工业陶瓷）.导电精细陶瓷总电导率的试验方法

[中文适用范围]： 本标准规定了采用DC（直流）四端子法测定导电精细陶瓷总电导率的试验方法。 该测试方法适用于离子迁移数为0.01或更小的导电精细陶瓷。 适用的电导率范围为1 S cm−1 至1000 S cm−1，温度范围高达1000 °C。 测试方法中表示的数值符合国际单位制（SI）。 本文件旨在用于燃料电池、电池和水电解等电极中使用的导电精细陶瓷的工业产品质量控制和材料开发。 [外文原描述]： 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 to 1 000 S cm−1 and the temperature range is up to 1 000 °C. The values expressed in the test method are in accordance with the International System of Units (SI). 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.
