Application Summary AI generated
This standard specifies the technical requirements, test methods, inspection rules, and packaging for tungsten-rhenium alloy wires used as thermocouple cathode materials and electronic emission materials. It is applied in high-temperature measurement instruments (e.g., thermocouples for industrial furnaces) and electronic devices requiring stable thermal electron emission, such as vacuum tubes and electron microscopes. The standard ensures consistent wire diameter, tensile strength, and thermal stability under extreme operating conditions.
