Significance and Use
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 , 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.
1.3.1 Annex A1 provides some precautionary information regarding the use of the required reagents.
1.3.2 Annex A2 describes a standard practice for obtaining a sample of the particulates present in a flowing stream of aviation turbine fuel.
1.3.3 Appendix X1 describes a test method for rating the particulate level in an aviation turbine fuel on the basis of the color of a filter membrane after sampling the fuel in the field.
1.3.4 Appendix X2 provides some safety precautions to avoid static discharge resulting from the accumulation of electrical charges in the fuel and on the equipment while following the procedures.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
