Note the product descriptors are generalizations. Historical Version s – view previous versions of standard. The other values showing converted units have d12500 rounded to the significant digits shown; as rounded values, they may numerically fall just outside of the actual limits established by the defining values. Work Item s – proposed revisions of this standard.
ICS Number Code A 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 has been determined by experiment.
This value is then further corrected to give the metric output.

Note that procedure paragraphs F1250 Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Table 1 shows the defining limits and their associated units in bold italics.
The liquid classifications listed here are typical terms used in the industry, but local nomenclature may vary.
Also shown in Table 1 are the limits converted to their equivalent units and, in the case of the densities, other base temperatures. The CTL Tables had generalized equations to correct glass hydrometer readings, and these corrections were part of the printed x1250 tables. This group includes substances with the commercial identification of: In such cases, the product should be allocated to the class appropriate to its density, not its descriptor.
The groups are defined as follows: The groups are defined as follows:.

Crude oils that have been stabilized for transportation or storage purposes and whose API gravities lie within that range are considered to be part of the Crude Oil group. Two sets of procedures are included for computing volume correction factor: The list is illustrative and is not meant to be all-inclusive. The commercial specification astj of some products may place their densities partly within an adjacent class for example, a low density diesel may lie in the jet fuel class.
These tables should be considered for use when:
