product under test and heat the aarroie to. 10*0, above that
temperature.

4, Immerse the bulb of a hydrometer of -a suitable range in the ' liquid and stir wall with a paper scale thermomater.
5o Adjust theJsetaperature to the desired point by controlling the steaa feed to the jacket. Continue stirring until the tempera ture remains - constant f or half a minute.

6. Note the temperature, quickly withdraw the thermometer anti
allow the hydrometer to silk Into the liquid at the center of the
cylinder.

7, Read the hydrometer scale at the point of the lower meniscus and record with the temperature<,
MOTSs Due to the opaque nature of crude Arcolors, it is necessary to estimate this reading. Usually It Is one scale division below the highest visible part of the scale.
8. Correct the specific gravity reading from the observed tempera ture to a temperature required by the specification for the product under test. Use the following table;
