The American Petroleum Institute provides procedures for calculating VCFs for Generalized Crude oils, Refined Products, Lubricating Oils, and Special Applications. These procedur

32、es are presented in API MPMS Ch. 11.12004/Adjunct to ASTM D1250-08/IP 200/08. The API has not previously addressed ethanol, considered a Special Application, in MPMS Ch. 11.1, so industry has used a variety of privately developed tables for both denatured 99+ % and denatured 95 % to 99 % fuel ethano

33、l VCFs. (Denaturant requirements vary by country and if this standard is being used outside the United States, refer to the local jurisdiction for denaturant requirements.) The most commonly used table has been that of a large ethanol supplier, and it appears that U.S. Customs and Border Protection

34、(CBP) and the Environmental Protection Agency (EPA) have adopted a variant of this table. The API, through a consortium of its member companies and in cooperation with the Renewable Fuels Association (RFA), commissioned an independent laboratory to take density measurements at various temperatures o

35、f pure (99.038 % by volume) ethanol and representative denatured fuel ethanols. The density data were obtained utilizing the best available commercial instrumentation and was then used to develop the VCFs provided in this standard.vii1Miscellaneous Hydrocarbon Product PropertiesDenatured Ethanol Den
