GB/T 36010-2018

This standard specifies the technical requirements, test methods, and temperature-electromotive force (EMF) tables for platinum-40%rhodium/platinum-20%rhodium thermocouple wires, which are used as high-temperature sensors in industrial furnaces, metallurgy, and glass manufacturing. It ensures accurate temperature measurement in environments ranging from 0°C to 1800°C, particularly in oxidizing or inert atmospheres where other thermocouples degrade. The standard is applied by manufacturers and calibration laboratories to verify the performance and interchangeability of these thermocouples for precision temperature control and process monitoring.
