1、Designation: D 2392 96 (Reapproved 2006)An American National StandardStandard Test Method forColor of Dyed Aviation Gasolines1This standard is issued under the fixed designation D 2392; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revisio
2、n, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This test method cove
3、rs the determination of the accept-ability of color of dyed aviation gasolines.1.2 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and dete
4、rmine the applica-bility of regulatory limitations prior to use. For specificwarning statements, see Annex A1.2. Summary of Test Method2.1 The hue and color intensity of a sample of the gasolineto be tested are compared with those of glass permanent-colorstandards.3. Significance and Use3.1 Aviation
5、 gasolines are dyed different colors for easyidentification of grade, thus minimizing possibilities for fuelingaircraft with fuel of the wrong grade.4. Apparatus4.1 Color Comparator, split-field, for viewing simulta-neously (by transmitted light) the sample to be tested and thecombination of the ref

Material5.1 The reference liquid can be eit
7、her distilled water or asample of the gasoline to be tested before the addition of dyeor lead alkyl fluid. (WarningGasoline is extremely flam-mable. See A1.1 and A1.2.)6. Procedure6.1 Clean the optical surfaces of the color comparator. Insertthe empty fluid tubes in the comparator and adjust the pos
8、itionof the light source until the intensities of the light from bothhalves of the comparator split-field are equal.6.2 Rinse and fill one of the tubes with the reference liquidto be used and insert the plunger. Wipe all excess referenceliquid from the outside of the tube and from the top of theplun
9、ger, and insert the tube on the left side of the comparator.6.3 Rinse and fill the other tube with the sample to be tested,and insert the plunger. Wipe all excess sample from the outsideof the tube and from the top of the plunger, and insert the tubein the right side of the comparator, so that it is
10、 directly belowthe larger of the two openings when the access door is closed.6.4 Insert the glass permanent-color standards into thecomparator and rotate the standards until the color section canbe viewed by transmitted light. Turn on the light source andcompare the two fields for hue and intensity
11、with the minimumand maximum color sections of the glass permanent-colorstandards.6.5 Determine if the hue is approximately the same as thestandard and if the intensity of the color is between, orequivalent to, the minimum and maximum, in which case thecolor of the sample is acceptable. If the hue is
12、 different fromthe standard or if the intensity lies outside the minimum andmaximum color sections, report the test as a fail.7. Report7.1 Report the color as Acceptable or Fail.8. Precision and Bias8.1 PrecisionIn the case of pass-fail data no generallyaccepted method for determining precision is c
13、urrently avail-able.8.2 BiasNo justifiable statement can be made on the biasin this test method for determining the acceptability of thecolor of dyed aviation gasoline because it is a pass-fail test.9.
