JJF 1184-2024 "Technical Specification for Temperature Field Testing of Thermocouple Verification Furnaces" applies to the temperature field testing of horizontal Thermocouple verification furnaces with a Temperature range between 300 ° C and 1500 ° C. The specification also applies to Miscellaneous electronically controlled heating equipment, provided that they are used to provide a uniform temperature field required for Thermocouple verification or calibrating. The referenced documents include calibrate specifications and standards involving various Thermocouple types, such as the JJG 75-2022 standard Platinum Rhodium 10-Platinum Thermocouple and the JJF 1262-2010 armored Thermocouple calibrate specification. This specification defines the concepts of axial and radial temperature fields, and methods of use for stationary and mobile couples. Thermocouple verification furnaces provide a stable temperature environment through their high temperature resistant ceramic furnace tubes, heating elements and temperature Control systems to ensure the accuracy and Reliability of Thermocouple during the calibrating process.
