The combustion shall be protected from drafts and the vapors allowed to burn spontaneously
until the liquid is consumed. Record the weight of the ash residue and calculate the percent ash
residue using the following equation:
weight of residue
% ash residue =
x 100
weight of sample
4.4.7 Iron. Iron shall be determined in accordance with ASTM E 202, sections 18 - 26.
4.4.8 Chlorides.
4.4.8.1 Standard chloride solution. Dissolve 0.458 gm of sodium chloride in distilled
water and dilute to 1000 ml in a volumetric flask. Pipet 10 ml of this solution into a 100 ml
volumetric flask, dilute to the mark with distilled water, and mix thoroughly. A 1.0 ml portion of
the second dilution is equivalent to one ppm Cl and is used as the standard when measuring the
25 ml sample.
4.4.8.2 Procedure. Introduce 25 ml of the sample into one of two 100 ml short form
Nessler tubes.
a. Into the second tube, pipet 1.0 ml of the standard chloride solution. Reserve as the
standard.
b. Add 5 drops of concentrated nitric acid to each tube and dilute to the mark with
distilled water.
c. Add 2 ml of 10 percent aqueous silver nitrate solution to each tube and mix
thoroughly.
d. Compare the turbidity of the sample with that of the standard by reviewing down
through the tubes against a dark background. If the turbidity of the sample is greater than that of
the standard, the chloride content is in excess of one ppm.
4.4.9 Flash point. The flash point shall be determined in accordance with ASTM D 92,
except that the fire point need not be determined.
4.4.10 Rejection criteria. Failure of any sample to meet any requirement of this
specification shall be cause to reject the lot or batch.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as
specified in the contract or order (see 6.2). When packaging of materiel is to be performed by
DoD or in-house contractor personnel, these personnel need to contact the responsible packaging
activity to ascertain packaging requirements. Packaging requirements are maintained by the
Inventory Control Point's packaging activities within the Military Service or Defense Agency, or
