TABLE 1 REDUCTION OF OBSERVED SPECIFIC GRAVITY TO SPECIFIC GRAVITY 15.6/15.6°C (60/60°F)
This table gives values of specific gravity 15.6/15.6°C (60/60°F) corresponding to specific gravities observed with a glass hydrometer at temperatures other than
60°F. The expression “Observed Specific Gravity” appears in this table because it is the term most generally used in industry. For specific gravities determined by
hydrometer, a more exact expression would be “hydrometer indication at the observed temperature.” This hydrometer indication differs slightly from the true specific
gravity at the observed temperature owing to the expansion or contraction of the glass hydrometer when its temperature differs from its calibration temperature of
60°F.
It is generally impracticable to determine a specific gravity at exactly 15.6°C (60°F) although it is at this temperature only that strictly correct results are obtained
with a standard glass hydrometer. In converting an observed specific gravity at the observed temperature tF (hydrometer indication of specific gravity t/60°F) to the
corresponding 60/60°F value, two corrections are possible. The first arises from the change in volume of the glass hydrometer with temperature, and the second
arises from the change in volume of the butadiene. This table takes into account only the change in volume of the butadiene because the change in volume ofthe
hydrometer is insignificant in comparison with the accuracy of the values for the change in volume of the butadiene.
This table must be entered with specific gravities measured with a glass hydrometer calibrated at 15.6/15.6°C (60/60°F)
Example—If the specific gravity observed on a hydrometer in butadiene at 40°F is 0.642, what is its specific gravity 60/60°F?
Enter the table in the column for “Observed Specific Gravity,” headed 0.640, and note that against an “Observed Temperature” of 40°F, the corresponding
specific gravity 60/60°F is 0.627
Likewise, note that for 0.645 specific gravity opposite 40°F, the corresponding specific gravity 60/60°F is 0.632
This represents an increase of 0.005 in specific gravity 60/60°F for an increase of 0.005 in the value at 40°F. Therefore, by simple proportion, an increase
in the specific gravity value noted at 40°F from 0.640 to 0.642 increases the corresponding specific gravity 60/60°F by 0.4 3 0.005 or 0.002
Then, the specific gravity 60/60°F corresponding to the observed specific gravity of 0.642 at 40°F is 0.627 + 0.002 or 0.629

TABLE 2 REDUCTION OF OBSERVED VOLUME TO 15.6°C (60°F) AGAINST SPECIFIC GRAVITY 60/60°F
This table gives the factors for converting butadiene volumes observed at temperatures other than 15.6°C (60°F) to the corresponding volumes at 60°F for values
of specific gravity 60/60°F in the range 0.621 to 0.634.
It is emphasized that the volume correction factors in this table make no allowance for the thermal expansion of tanks and other types of containers.
This table must be entered with specific gravity values 15.6/15.6°C (60/60°F) and volumes measured at Fahrenheit temperatures.
Example—What is the volume at 60°F of 45 500 U.S. gal at 35°F of butadiene whose specific gravity 60/60°F is 0.625?
Enter the table in the column for “Specific Gravity 60/60°F’’ headed 0.625, and note that against an “Observed Temperature’’ of 35°F the factor is
1.027
Hence, 1 U.S. gal of butadiene of specific gravity 0.625 at 60/60°F and measured at 35°F occupies a volume at 60°F of 1.027 U.S. gal
Then 45 500 U.S. gal measured at 35°F occupy a volume at 60°F of 45 500 3 1.027 or 46 728 U.S. gal

ASTM D7061-23(Test Method)
Standard Test Method for Measuring n-Heptane Induced Phase Separation of Asphaltene-Containing Heavy Fuel Oils as Separability Number by an Optical Scanning Device

SIGNIFICANCE AND USE
5.1 This procedure describes a rapid and sensitive method for estimating the stability reserve of an oil. The stability reserve is estimated in terms of a separability number, where a low value of the separability number indicates that there is a stability reserve within the oil. When the separability number is between 0 to 5, the oil can be considered to have a high stability reserve and asphaltenes are not likely to flocculate. If the separability number is between 5 to 10, the stability reserve in the oil will be much lower. However, asphaltenes are, in this case, not likely to flocculate as long as the oil is not exposed to any worse conditions, such as storing, aging, and heating. If the separability number is above 10, the stability reserve of the oil is very low and asphaltenes will easily flocculate, or have already started to flocculate.  
5.2 This test method can be used by refiners and users of oils, for which this test method is applicable, to estimate the stability reserves of their oils. Hence, this test method can be used by refineries to control and optimize their refinery processes. Consumers of oils can use this test method to estimate the stability reserve of their oils before, during, and after storage.
FIG. 1 Schematic Representation of a Typical Measurement Using an Optical Scanning Device  
5.3 This test method is not intended for predicting whether oils are compatible before mixing, but can be used for determining the separability number of already blended oils. However, oils that show a low separability number are more likely to be compatible with other oils than are oils with high separability numbers.
SCOPE
1.1 This test method covers the quantitative measurement, either in the laboratory or in the field, of how easily asphaltene-containing heavy fuel oils diluted in toluene phase separate upon addition of heptane. This is measured as a separability number (%) by the use of an optical scanning device.  
1.2 The test method is limited to asphaltene-containing heavy fuel oils. ASTM specification fuels that generally fall within the scope of this test method are Specification D396, Grade Nos. 4, 5, and 6, Specification D975, Grade No. 4-D, and Specification D2880, Grade Nos. 3-GT and 4-GT. Refinery fractions from which such blended fuels are made also fall within the scope of this test method.  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Determination of Hydrocarbon Impurities in High Purity Propylene by Gas Chromatography

SIGNIFICANCE AND USE
5.1 High-purity propylene is required as a feedstock for various manufacturing processes, and the presence of trace amounts of certain hydrocarbon impurities may have adverse effects on yield or catalyst life. This test method is suitable for use as a benchmark in setting commercial specifications, for use as an internal quality control tool, and for use in development or research work.
SCOPE
1.1 This test method is used for the determination of hydrocarbon impurities in propylene (propene) material of 97 % by mass or greater purity (concentrates). These impurities are determined in the concentration range of 0.35 mg/kg to 8575 mg/kg and includes the following components: methane, ethane, ethylene, propane, acetylene, isobutane, propadiene, normal butane, trans-2-butene, butene-1, isobutylene, cis-2-butene, isopentane, methylacetylene, normal pentane, and 1,3-butadiene.
Note 1: Optionally, the analysis may include the determination of pentenes/hexanes and heavier components, see 6.3.  
1.2 This test method does not determine non-hydrocarbon impurities, and additional tests may be necessary to fully characterize the propylene sample.

Standard Test Method for Trace Carbonyl Sulfide in Propylene by Gas Chromatography

SIGNIFICANCE AND USE
5.1 In processes producing propylene, COS usually remains with the C3 hydrocarbons and must be removed, since it affects product quality. COS acts as a poison to commercial polymerization catalysts, resulting in deactivation and costly process downtime.  
5.2 Accurate gas chromatographic determination of trace COS in propylene involves unique analytical problems because of the chemical nature of COS and idiosyncracies of trace level analyses. These problems result from the reactive and absorptive nature of COS, the low concentration levels being measured, the type of detector needed, and the interferences from the propylene sample matrix. This test method addresses these analytical problems and ways to properly handle them to assure accurate and precise analyses.  
5.3 This test method provides a basis for agreement between two laboratories when the determination of trace COS in propylene is important. The test method permits several calibration techniques. For best agreement between two labs, it is recommended that they use the same calibration technique.
SCOPE
1.1 This test method covers the determination of traces of carbonyl sulfide (COS) in propylene. It is applicable to COS concentrations from 0.5 mg/kg to 4.0 mg/kg (parts per million by mass). See Note 1.  
Note 1: The lower limit of this test method is believed to be below 0.1 mg/kg, depending on sample size and sensitivity of the instrumentation being used. However, the cooperative testing program was conducted in the 0.5 to 4.0 range due to limitations in preparing commercial test mixtures.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Section 9.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
