Scope

This specification applies to the calibration of non-removable tungsten-rhenium thermocouples with a temperature range of (0–2,300) °C. The calibration below 1,100 °C applies to tungsten-rhenium thermocouples with a protective tube length of not less than 300 mm, and the calibration between 1,100 and 2,300 °C applies to tungsten-rhenium thermocouples with a protective tube length of not less than 600 mm.
Other types of high-temperature thermocouples can refer to this specification for calibration.
