Weights and specific gravities of specially denatured alcohol.

§ 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 °C. (60 °F.) is as listed in this section. The specific gravity of each formula of specially denatured alcohol at 15.56 °C./15.56 °C. (60 °F./60 °F.) in air is as listed in this section. (Weight of 1 gallon of water at 15.56 °C. (60 °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.
