At the end of the exposure period, the weight-loss shall be determined and the corrosion rate calculated as required. 4.67.7.2 Localized corrosion. 4.67.7.2.1 Test specimens. The test specimens shall consist of FINS S30400 CRES milled to finished dimensions of approximately Me inch thick, V2 inch wide, and 3 inches long. After degreasing with acetone, rinsing with distilled water, and air drying before exposure, the specimens shall be pretreated by immersion in a 1:9 concentrated nitric acid-water solution for the period of 5 minutes. 4.67.7.2.2 Procedure. Ten specimens shall be girdled lengthwise with a clean Me to Vs inch wide band o f a good grade of gum rubber of a size such that the band is taut during the test. Because of the poor quality of most commercial rubber bands, it is recommended that the bands for this test be cut from VA inch flat width pure gum amber tubing (Preiser Scientific Rubber tubing, Pure Gum, Gooch type, Hc-inch thin wall, pure gum amber tubing, very elastic, especially made for Gooch crucibles, or equal). This tubing is most easily cut into uniform strips with a blade-type papercutter, but can also be cut with sharp shears. The specimens girdled with the rubber bands shall be placed in a 600 mL beaker so that no contact is made between individual specimens. A V^-inch layer of glass beads shall be introduced into the beaker to aid in stabilizing specimen position. Enough liquid shall be added to completely immerse the specimens, and a watch-glass shall be placed over the beaker to retard evaporation (but allow air access) and act as a dust cover, and the assemblies allowed to stand at room temperature for 60 days. 4.67.7.2.3 Results. The specimens shall be monitored daily over the 60-day period to ascertain the presence or absence of pitting. These daily examinations shall be made without disturbing hie test (other than removing the cover). Corrosion is customarily signaled by the appearance of a dark spot which, if removed after sufficient exposure, discloses a corrosion pit. If the suspected area cannot be positively identified by the naked eye, it can be at a magnification of 10X. At the end of the test, each specimen shall be inspected carefully with particular attention being given to the edges of the specimens and those areas of the specimens under or adjacent to the rubber bands. 10X magnification shall be used, if necessary. 4.67.8 Total halides. The halide content shall be determined to be in accordance with ASTM D1821, except for the following modifications: a. Procedure: (1) Weight 40.1g or add 40.1 mL of concentrate into a 250 mL beaker (2) Add 75 mL of acetone. Add 2 mL of dilute nitric acid (one volume of concentrated acid to 60 volumes of water). 11 US00005951 MIL-DTL-24385G(SH) DRAFT DATED 18 October 2013 b. The calculation shall be modified as follows: Halide content, p/m=44.4(A-B). 4.62.9 Dry chemical compatibility. The foam's compatibility with potassium bicarbonate dry chemical extinguishing agent shall be determined by measuring the bumback time in the presence of dry chemical. 4.67.9.1 Test materials. The fuel shall be unleaded gasoline conforming to ASTM D439. The dry chemical agent shall conform to O-D-1407. The sieve shall be an 8-inch diameter, 40 mesh sieve conforming to Type I, Style AofRR-S-366. 4.67.9.2 Test procedure. A 28-square-foot fire test shall be conducted in accordance with 4.6.13.1 using Type 3 or 6 AFFF sea water solution, as required. Before placing the burning pan, one pound of dry chemical agent shall be evenly distributed over the foam blanket with die aid of a service on a long handle. This shall be accomplished within a 30-second period so that the total time from end of foam application to placement of the burning pan will not be longer than 90 seconds. The bumback time shall be determined as in 4.6.13.1.4. 4.67.10 Stability. 4.67.10.1 Sample preparation. Samples of concentrate, and Type 3 and Type 6 AFFF fresh water and sea water solution, as appropriate, shall be prepared in sufficient quantity to perform the required tests. One liter of each shall be placed in lightly stoppered glass cylinders. All samples shall then be stored at 652.0 C for a period of 10 days. The samples shall then be subjected to the following tests: a. Spreading coefficient b. Foamability c. Film formation and sealability d. Fire performance (28 ft2) e. Stratification f. Precipitation 4.6.4 4.6.5 4.6.6 4.6.13.1 4.6.14 4.6.152 Editor's Note: Recommend moving last sentence above and lettered list to a new paragraph 4.6.10.2 since it describes the test procedures and not instructions for preparing the sample. 4.67.11 Compatibility. 4.67.11.1 Sample preparation. The Government will provide samples of appropriate qualified product(s) to manufacturers officially authorized to submit candidate material for qualification (see 3.3.3). Mixtures, of the Type 3 and Type 6 concentrates, to be tested shall be prepared in sufficient quantities to perform the required tests. (For qualification testing, the testing activity will determine the number of product mixtures to be evaluated and the ratio of product comprising these mixtures.) Additionally, 3 percent of Type 3 or 6 percent o f Type 6 AFFF fresh water and sea water solutions shall be prepared from each concentrate mixture. One liter of each shall be placed in lightly stoppered glass cylinders. The samples shall be stored at 652.0 C for a period of 10 days. The samples shall then be subjected to the following tests: a. Foamability b. Film formation and sealability c. Fire performance (28 ft2) d. Stratification e. Precipitation 4.6.5 4.6.6 4.6.13.1 4.6.14 4.6.15 Editor's Note: I am concerned that the language above is not allowed in a specification, but I need to research further. It seems odd that the Government would provide a QPL applicant with product from a qualified manufacturer. If each manufacturer can meet the other requirements o f the specification, the paragraph seems redundant. Please consider removing. 2 In the preparation of the samples to be used for the precipitation test, the synthetic sea water shall be filtered prior to use. 12 US00005952 MIL-DTL-24385G(SH) DRAFT DATED 18 October 2013 4.7.12 Environmental impact. 4.67.12.1 Toxicity.
