Enclosed-scale calorimeter thermometers
This standard was last reviewed and confirmed in 2017. Therefore this version remains current.
The specified thermometers are of the mercury-in-glass enclosed-scale type with short range. They are used in bomb calorimetry and for other purposes where an accurate measurement of a change of temperature is required. They are not provided with auxiliary scales and are therefore not suited for measurement of the absolute temperature. The requirements specify material, construction, scale, and accuracy.
