NOTE 24—The observed barometric reading does not have to be
corrected to a standard temperature and to standard gravity. Even without
performing these corrections, the corrected temperature readings for the
same sample between laboratories at two different locations in the world
will, in general, differ less than 0.1 °C at 100 °C. Almost all data obtained
earlier have been reported at barometric pressures that have not been
corrected to standard temperature and to standard gravity.
