MIL-DTL-12276E(MR)
Percent toluene, v/v = (area of toluene peak) x (1.017) * x (10) **
(area of benzene peak)
Percent ethylbenzene, v/v = (area of ethylbenzene peak) x (1.054) * x (10) **
(area of benzene peak)
where; * = the correction factor for the detector response.
** = the percentage of internal standard added.
NOTE: Sensitivity of the instrument should be adjusted to keep peaks from running off
the scale. Appropriate corrections must be made for changes in sensitivity when
computing the peak areas.
4.3.6.3 Test for olefinic or cycle-olefinic compounds. Take 2 test tubes and place 2 drops of
the distillate in each. Dissolve the first sample in 1ml. of chloroform and add 1 drop of 1
percent bromine in chloroform. Shake and allow to set for 5 minutes. A positive test is
indicated by the complete absence of yellow color when observed against a white
background. Dissolve the second sample in 1 ml. of acetone and add 1 drop of 1 percent
permanganate solution (1 gram of potassium permanganate crystals in 95 mls. of acetone
and 5 mls. of water). Shake and allow to set for 2 minutes. A positive test is indicated by
the decoloration of the purple solution. The solvent is considered to fail the test for olefinic
and cyclo-olefinic compounds if either of the above tests is positive (see 3.2.3 and 6.5).
4.3.6.4 Tests for ketones.
4.4.6.4.1 Reagent. Two grams of 2,4-dinitrophenylhydrazine plus 4 mls. of concentrated
sulfuric acid plus 30 mls. methanol (add slowly plus 10 mls. water).
4.3.6.4.2 Procedures. Pipette 1 ml. of reagent into 20 by 170 mm test tube. Add 10 drops of
distillate (see 4.3.6.1) and shake for 30 seconds. A yellow precipitate or cloud in the reagent
layer indicates the presence of ketones. Run a blank using one milliliter of reagent and 10
drops of mineral spirits.
4.3.7 Resistance to chemicals and solvents. A minimum of 18 panels shall be required .
Test panels, 1 x 2 ½ x 0.026 inches in size, shall be prepared and coated as specified in 4.3.1.
A minimum of one coated panel for each of the three schedules specified in 4.3.1 shall be
tested separately for resistance to the following chemicals and solvents by immersion. A
separate panel shall be used for each individual test.
