GB/T 37253-2018 specifies the test method for ion conductivity of functional Pottery and porcelain for oxygen Sensors. The standard requires the selection and pretreatment of functional Pottery and porcelain samples to ensure that the sample status meets the standard. With the help of professional testing equipment, under specific temperature, humidity and other conditions, the measurement of parameters such as the current generated by ion conduction of functional Pottery and porcelain under the action of electric field is calculated to obtain the ion conductivity. The standard specifies the test environment, equipment calibrating and operation process to ensure accurate and reliable data, providing key technical support for the research and development, production and quality control of functional Pottery and porcelain for oxygen Sensors, and helping to improve the performance of oxygen Sensors.
