In late 2011, API MPMS Chapter 11.3.3, Miscellaneous Hydrocarbon Product Properties – Ethanol Density and Volume Correction Factors was published.
The standard includes implementation procedures for both pure and denatured ethanol.
For volume or density correction from observed temperature to 60 °F, the implementation procedure given in API MPMS Ch. 11.1-2004 shall be ...view middle of the document...
This applies to all vessel and barge shipments, including imports and exports involving discharges into and loadings from storage tank facilities, refineries and admissions to and transfers to or from foreign trade zones.
These tables should not be confused with Gauging Manual Table 7 (27 CFR 30.67) used by the Alcohol and Tobacco Tax and Trade Bureau (TTB), which applies to “spirituous liquors” (drinking alcohol). This old table (1913) is of limited utility as it covers 18 °F to 100 °F in 2 °F increments and provides three decimal VCF’s. (http://www.ttb.gov/foia/gauging_manual_toc.shtml#27:22.214.171.124.25.5.507.7).
Additionally, for the measurement of the quantity of non-denatured or denatured bulk fuel use ethanol for CBP purposes whose purity and other specifications fall outside the scope of the API-MPMS Chapter 11.3.3 standard, the ASTM D1250 standard shall be used. Ethanol of these other purities shall be considered to be a “Special Application” within the ASTM D1250 standard.
