GSO ASTM D1319:2011 Scope
1.1 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.
1.2 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.
1.3 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.
1.4 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.
1.5 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.
1.6 The values stated in SI units are to be regarded as
standard. No other units of measurement are included in this
standard.
1.7 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.
