This International Standard specifies, for use in the preparation of measurement tables for liquids, a conventional value for the thermal cubic expansion coefficient of glass hydrometers. It states how the indications of hydrometers having a thermal cubic expansion coefficient differing from the recommended conventional value may be corrected for use in connection with measurement tables in the construction of which the conventional value has been used.
