Excerpt from Circular of the Bureau of Standards, Vol. 8: Testing of Thermometers; Issued June 30, 1911
It is well known that the scale of temperature defined by a mercurial thermometer is dependent upon the composition and treatment of the glass. Even samples of glass from the same pot show differences in this respect. Mercury in glass thermometers, although capable of very great precision when properly constructed and used with due precautions, are therefore not suited to establish the standard scale of temperature.
International Hydrogen Scale - The temperature scale which has come into almost world-wide use in the interval 3 5° to 100° C is the hydrogen scale of the International Bureau of Weights and Measures, as defined by the 'following resolution of the International Committee on Weights and Measures, adopted October 15, 1887.
