ASTM D 1319 Document Information:
Title
Standard Test Method for Hydrocarbon Types in Liquid Petroleum Products by Fluorescent Indicator Adsorption
ASTM International
Publication Date:
Oct 15, 2008
Scope:
This test method covers the determination of hydrocarbon types
over the concentration ranges from 5 to 99 volume % aromatics, 0.3
to 55 volume % olefins, and 1 to 95 volume % saturates in petroleum
fractions that distill below 315°C. This test method may apply to
concentrations outside these ranges, but the precision has not been
determined. Samples containing dark-colored components that
interfere in reading the chromatographic bands cannot be
analyzed.
NOTE 1—For the determination of olefins below 0.3 volume %,
other test methods are available, such as Test Method D 2710.
This test method is intended for use with full boiling range
products. Cooperative data have established that the precision
statement does not apply to narrow boiling petroleum fractions near
the 315°C limit. Such samples are not eluted properly, and results
are erratic.
The applicability of this test method to products derived from
fossil fuels other than petroleum, such as coal, shale, or tar
sands, has not been determined, and the precision statement may or
may not apply to such products.
This test method has two precision statements depicted in
tables. The first table is applicable to unleaded fuels that do not
contain oxygenated blending components. It may or may not apply to
automotive gasolines containing lead antiknock mixtures. The second
table is applicable to oxygenate blended (for example, MTBE,
ethanol) automotive spark ignition fuel samples with a
concentration range of 13–40 volume percent aromatics, 4–33 volume
percent olefins, and 45–68 volume percent saturates.
The oxygenated blending components, methanol, ethanol,
methyl-tert-butylether (MTBE),
tert-amylmethylether (TAME), and
ethyl-tert-butylether (ETBE), do not interfere with the
determination of hydrocarbon types at concentrations normally found
in commercial blends. These oxygenated components are not detected
since they elute with the alcohol desorbent. Other oxygenated
compounds shall be individually verified. When samples containing
oxygenated blending components are analyzed, correct the results to
a total-sample basis.
The values stated in SI units are to be regarded as standard. No
other units of measurement are included in this standard.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use. For specific warning statements, see
Section 7, 8.1, and 10.5.
