3、.1.Scope1.1 This test method covers the determination of particulatecontaminant in aviation turbine fuel using a field monitor.1.2 There are two test methods described.The basic testmethod is used to evaluate the level of contamination gravi-metrically.The second test method,presented in Appendix X1
4、,describes a color rating technique that is used for rapidqualitative assessment of changes in contamination level with-out the time delay required for the gravimetric determinationsby stringent laboratory procedures.1.3 There are two Annexes and two Appendixes in this testmethod.1.3.1 Annex A1 prov
