ASTM D2276-22

5.1?This test method provides a gravimetric measurement of the particulate matter present in a sample of aviation turbine fuel by line sampling. The objective is to minimize these contaminants to avoid filter plugging and other operational problems. Although tolerable levels of particulate contaminants have not yet been established for all points in fuel distribution systems, the total contaminant measurement is normally of most interest. The Appendix X1 color rating method is useful for fuel system monitoring purposes. No quantitative relationship exists between gravimetric and color rating test results.

1.1?This test method covers the determination of particulate contaminant in aviation turbine fuel using a field monitor.

1.2?There are two test methods described. The basic test method is used to evaluate the level of contamination gravimetrically. The second test method, presented in Appendix X1, describes a color rating technique that is used for rapid qualitative assessment of changes in contamination level without the time delay required for the gravimetric determinations by stringent laboratory procedures.

1.3?There are two Annexes and two Appendixes in this test method.

1.4?The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.5?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.

1.6?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.
