(Test Method)Standard Test Method for Color of Dyed Aviation Gasolines
Standard Test Method for Color of Dyed Aviation Gasolines
SIGNIFICANCE AND USE
3.1 Aviation gasolines are dyed different colors for easy identification of grade, thus minimizing possibilities for fueling aircraft with fuel of the wrong grade.
SCOPE
1.1 This test method covers the determination of the acceptability of color of dyed aviation gasolines.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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. For specific warning statements, see Annex A1.

2. Summary of Test Method
2.1 The hue and color intensity of a sample of the gasoline to be tested are compared with those of glass permanent-color
standards.
3. Significance and Use
3.1 Aviation gasolines are dyed different colors for easy identification of grade, thus minimizing possibilities for fueling aircraft
with fuel of the wrong grade.
4. Apparatus
4.1 Color Comparator, split-field, for viewing simultaneously (by transmitted light) the sample to be tested and the combination
of the reference liquid and the glass permanent-color standard.

5. Material
5.1 The reference liquid can be either distilled water or a sample of the gasoline to be tested before the addition of dye or lead
alkyl fluid. (Warning—Gasoline is extremely flammable. See A1.1 and A1.2.)
6. Procedure
6.1 Clean the optical surfaces of the color comparator. Insert the empty fluid tubes in the comparator and adjust the position
of 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 liquid to be used and insert the plunger. Wipe all excess reference liquid
from 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 from the outside
of 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 the
larger of the two openings when the access door is closed.
