PART 21_FORMULAS FOR DENATURED ALCOHOL AND RUM--Table of Contents

 Subpart H_Weights and Specific Gravities of Specially Denatured Alcohol

Sec.  21.161  Weights and specific gravities of specially denatured alcohol.


    The weight of one gallon of each formula of specially denatured
alcohol at 15.56 [deg]C. (60 [deg]F.) is as listed in this section. The
specific gravity of each formula of specially denatured alcohol at 15.56
[deg]C./15.56 [deg]C. (60 [deg]F./60 [deg]F.) in air is as listed in
this section. (Weight of 1 gallon of water at 15.56 [deg]C. (60 [deg]F.)
is 8.32823 pounds in air.)

                        Weights and Specific Gravities of Specially Denatured Alcohol \1\
 [Slight deviations from this table may occur due to variations in specific gravities of authorized denaturants.
      Values for 190 proof determined experimentally in air. Other values calculated from these gravities.]
