Standard Test Method for Determination of Cycloparaffin Content in Saturated ATJ-SPK Jet Fuel Gas ChromatographyTranslate name
STANDARD published on 1.7.2020
Designation standards: ASTM D8302-20
Publication date standards: 1.7.2020
The number of pages: 20
Approximate weight : 60 g (0.13 lbs)
Country: American technical standard
Category: Technical standards ASTM
ATJ-SPK jet fuel, butanol, butanols, cycloparaffin, gas chromatography, paraffin,
|Significance and Use|
5.1 This test method applies specifically to the ATJ-SPK jet fuel as specified in Specification , section A5.4.1, derived from isobutanol and follows the fuel fingerprint described in the annex of this test method. It may not apply to other types of ATJ-SPK fuels.
5.2 Table A2.2 in Specification prescribes cycloparaffin concentration be a maximum of 15 % by mass.
5.3 Due to the nature of the chemical composition of ATJ-SPK jet fuel, standard analysis of the sample by Test Method for cycloparaffin content may yield a higher concentration of cycloparaffins than are actually present in the sample.
5.4 This method alleviates the potential for overestimating the cycloparaffin concentration by measuring the concentration of identified paraffins. Any remaining unidentified compounds are classified as potential cycloparaffins.
1.1 This test method covers the determination of cycloparaffin content by gas chromatography of the saturated ATJ-SPK jet fuel as specified in Specification , section A5.4.1, derived from isobutanol and follows the fuel fingerprint described in the Annex of this test method.
1.2 The working range for the test method is for cycloparaffin content in the range of 1 % to 15 % by mass.
1.3 The test method has an interim precision and will be updated once an extended ILS is conducted.
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.
