Specifies thermometers of the mercury-in-glass solid-stem type of short range with enamel back. They are used in bomb calorimetry and for other purposes where an accurate measurement of a change of temperature is required. They are not suited for measurement of the absolute temperature because they are not provided with auxiliary scales. The requirements specify material, construction, scale, and accuracy.
