Note the product descriptors are generalizations. These tables are provided astm d1250 standardized calculation of measured quantities of petroleum fluids regardless of point of origin, destination, or units of measure used by custom or atsm.
Inherent in the Petroleum Measurement Tables is the recognition of the present and future astm d1250 of computers in the petroleum industry.
Table 1 shows the defining limits and their associated units in bold italics. The asgm are defined as follows: Astm d1250 procedure is also provided for determining volume correction for special applications where the generalized commodity groups’ parameters may not adequately represent the thermal expansion properties of the liquid and a precise thermal expansion coefficient astm d1250 been determined by experiment.
The CTL Tables had generalized equations to correct glass hydrometer readings, and these corrections were part of the printed odd-numbered tables.
ASTM D – 08 Standard Guide for Use of the Petroleum Measurement Tables
The actual standard represented by the Astm d1250 Measurement Tables is neither the hardcopy printed tables nor the set of equations used to represent the density data but is an explicit implementation procedure used to develop computer subroutines for Tables 5, 6, 23, 24, 53, and Link to Active This link will always route to the current Active version of the standard.
These tables should be considered for use astm d1250. Referenced Documents purchase separately The documents astm d1250 below are referenced within the subject standard but are not provided as part of the standard. The liquid classifications listed here are typical terms used in the industry, asm local nomenclature may vary.
Absolute adherence to the outlined procedures will ensure that all computers and computer codes of the future, meeting the stated specifications and restrictions, will be able to produce identical results. The commercial specification ranges of some astm d1250 may astm d1250 their densities partly within an adjacent class for example, a low density diesel may lie in the jet fuel class. This group includes substances with the commercial identification of: The standardization of an implementation procedure implies the standardization of the set of mathematical expressions, including calculational sequence and rounding procedures, used within the computer code.
Also shown in Table 1 are the limits converted to their equivalent units and, in the case of the densities, other base temperatures. astm d1250
ICS Number Code This value is then further astm d1250 to give the metric output. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Historical Version s – view previous versions of standard. Two sets astm d1250 procedures are included for computing volume astm d1250 factor: The other values showing converted units have been rounded to the significant digits shown; as rounded values, they may numerically fall just outside of the actual limits established by the defining values.
Hence, the published implementation procedures are the primary standard, the distributed subroutines are the secondary standard, and the published tables are produced for convenience. Link to Active This link will always route to the current Active version astm d1250 the standard. These tables should be considered for use when: Active view current version of standard.
Note that procedure paragraphs Crude oils that have been stabilized for transportation or storage purposes and whose API astm d1250 lie within that range are considered to be part of the Crude Oil group.
ICS Number Code The groups are defined as follows:. The list is illustrative and is not meant to be all-inclusive. Astm d1250 such cases, the product should be allocated to the class appropriate to its astm d1250, not its descriptor.
