35、-80, IP 200/80). This standard gives the following equivalents for any value of API gravity at 60 F: relative density at 60 F (old Table 3); absolute density at 60 F; absolute density at 15 C (old Table 3); pounds per U.S. gallon at 60 F in vacuo and in air (old Table 8); U.S. gallons per pound at 6

36、0 F in vacuo and in air (old Table 8); short tons per 1000 U.S. gallons at 60 F in vacuo and in air (old Table 9); U.S. gallons per short ton at 60 F in vacuo and in air (old Table 10); short tons per barrel at 60 F in vacuo and in air (old Table 9); barrels per short ton at 60 F in vacuo and in air

37、 (old Table 10); long tons per 1000 U.S. gallons at 60 F in vacuo and in air (old Table 11); U.S. gallons per long ton at 60 F in vacuo and in air (old Table 12); long tons per barrel at 60 F in vacuo and in air (old Table 11); barrels per long ton at 60 F in vacuo and in air (old Table 12); metric

38、tons per 1000 U.S. gallons at 60 F in vacuo and in air (old Table 13); metric tons per barrel at 60 F in vacuo and in air (old Table 13); barrels per metric ton at 60 F in vacuo and in air; cubic metres per short ton at 15 C in vacuo and in air (old Table 14); cubic metres per long ton at 15 C in va

39、cuo and in air (old Table 14).While not related to API gravity, the following are included for user convenience: U.S. gallons at 60 F to litres at 15 C (old Table 4); barrels at 60 F to litres at 15 C (old Table 4);This standard is intended for application to bulk liquid quantities.This standard pro

40、vides implementation procedures for conversion of API gravity at 60 F to equivalent densities in both in vacuo and in air values. A derivation of the in air equation is presented in Section B.4. In air values reflect the buoyancy effect of air if a substance were to be weighed in the air, and thus a

41、re slightly less than in vacuo values by approximately 0.1 % to 0.2 %. Although in air implementation procedures are presented in this standard in recognition viiof certain common industry practices, in vacuo values are recommended because they more accurately represent the amount of material presen

42、t. Furthermore, as there is no known technical reason for the continued use of API gravity in the oil industry, absolute density is recommended instead (see API MPMS Ch. 11.5.3). This standard is presented, however, for the convenience of certain current common industry practices.viii1Chapter 11Phys

43、ical Properties DataSection 5Density/Weight/Volume IntraconversionPart 1Conversions of API Gravity at 60 FImplementation GuidelinesThis revised standard is effective upon the date of publication and supersedes the applicable parts of API MPMS Ch. 11.1-1980, Volumes XI/XII. However, due to the nature

44、 of the changes in this revised standard, it is recognized that guidance concerning an implementation period may be needed in order to avoid disruptions within the industry and ensure proper application. As a result, it is recommended that this revised standard be utilized on all new applications no

45、 later than TWO YEARS after the publication date. An application, for this purpose, is defined as the point where the calculation is applied.Once the revised standard is implemented in a particular application, the previous standard will no longer be used in that application.However, the use of API

46、standards remains voluntary and the decision on when to utilize a standard is an issue that is subject to the negotiations between the parties involved in the transaction.1 ScopeThese intraconversion tables are applicable to all crude oils, petroleum products, and petrochemicals.2 ReferencesThe foll
