2、ision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope Scope*1.1 This test method covers the deter

For specific warning statements, see Annex A1.2. Summary of Test Method2.1 The hue and color intensity of a sample of the ga

5、soline to be tested are compared with those of glass permanent-colorstandards.3. Significance and Use3.1 Aviation gasolines are dyed different colors for easy identification of grade, thus minimizing possibilities for fueling aircraftwith fuel of the wrong grade.4. Apparatus4.1 Color Comparator, spl

Material5.1 The reference liquid can be either distilled water or a sample of the gasoline to be tested before the addition of dye or leadalkyl fluid. (WarningGasoline is extremely flammable. See A1.1 and A1.2.)6. Proced

8、ure6.1 Clean the optical surfaces of the color comparator. Insert the empty fluid tubes in the comparator and adjust the positionof the light source until the intensities of the light from both halves of the comparator split-field are equal.6.2 Rinse and fill one of the tubes with the reference liqu

9、id to be used and insert the plunger. Wipe all excess reference liquidfrom the outside of the tube and from the top of the plunger, 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 fr

10、om the outsideof the tube and from the top of the plunger, and insert the tube in the right side of the comparator, so that it is directly below thelarger of the two openings when the access door is closed.1 This test method is under the jurisdiction of ASTM Committee D02 on Petroleum Products Produ
