MIL-F-24385F where: ~Yi ~Ya~ Xi. = Spreading coefficient 56 = Surface tension of cyclohexane as determined in 4.7.4.1 = Surface tension of AFFF solution as determined in 4.7.4.1 & = Interfacial tension between liquids as determined in 4.7A2. & 4.7.4.1 Surface tension. The surface tension of 3 0.05 percent of type 3 or 6 0.1 percent of type 6 by volume in distilled water, as appropriate, and of reagent grade cyclohexane shall be determined with a DuNoy tensiometer, or equal, at 23 C 2.0 C in accordance with ASTM D1331. ^Where sea water is required for tests, synthetic sea water in accordance with ASTM D1141 shall be used. A sea salt mixture conforming to this standard may be purchased from Lake Products Company, Inc., P.O. Bax 2248, St. Louis, Missouri 63043. 4.7.4.2 Interfacial tension. The interfacial tension between 3 0.05 percent of type 3 or 6 0.1 percent of type 6 by volume in distilled water, as appropriate, and reagent grade cyclohexane shall be determined with a DuNoy tensiometer, or equal, at 23 C 2.0 C until the readings come to equilibrium and in accordance with ASTM D1331. 4.7.5 Foamability. The foam shall be generated by means of a special 2 gallons per minute (gal/min) test nozzle. The basic nozzle, as made by National Foam System, Inc., Lionville, Pennsylvania, (or equal) shall be modified by shortening the length of the foam barrel from 21/2 to 1-1/4 inches, and by adding a "wing-tip" spreader on the outlet. The spreader shall have a 1/8 inch wide, circular orifice, 1-7/8 inches long. (It may be made by slightly compressing a Bernz-o-matic TX-1527, or equal, flame spreader). A print of the nozzle construction is available from the Naval Research Laboratory, Code 6180, Washington, DC 20375. During foam sample collection, the nozzle inlet pressure shall be maintained at a gauge pressure of 100 pounds per square inch (lb/in2), and the solution temperature at 23 C 5.0 C. The nozzle shall be held at hip height and directed onto the backboard from a distance of 4 to 6 feel. The method and procedure shall be in accordance with NFPA 412. Foamability shall be run on 6 percent fresh and sea water solutions of the type 6 concentrate and 3 percent fresh and sea water solutions of the type 3 concentrate. 4.7.6 Film formation and sealability. 4.7.6.1 Test equipment. A CRES graduated measure of 1,000 milliliter (mL) capacity (41/2 inches in diameter, 5 inches deep; Cole-Parmer Co., Chicago, Illinois, or equal) shall be fitted with two retaining clips at the top edge. The clips serve to restrain a cone 5 inches in 11 US00005917 Downloaded from http://www.everyspec.com on 2011-05-03T15:11:47. MIL-F-24385F height and 4-3/4 inches in diameter, made of 80-mesh perforated CRES, in an inverted position inside the measure. The 2 gal/min nozzle specified in 4.7.5 shall be used for foam production. 4.7.6.2 Test procedure. After placing 400 mL of water and 200 mL of 98-percent cyclohexane in the measure, 200 mL of freshly-made foam shall be poured onto the fuel. The inverted cone shall be pushed down into the measure, thereby pushing most of the foam aside but allowing the film-producing liquid to creep in through the mesh openings. A foam-free surface shall be created by manually scooping out most of the residual foam from the center of the cone. After a 1-minute waiting period, a pilot flame shall be passed over the fuel surface at a height of about 1/2 inch. A small flash is permitted, but no sustained ignition shall result, if an effective vapor seal is present. A 1-inch long pilot flame shall be provided with a hand-held propane cylinder fitted with a capillary tubing outlet. 4.7.7 Corrosion. The liquid for immersion of the metal specimens for general corrosion and localized corrosion tests shall consist of the concentrate diluted by 10 percent by volume with sea water. 4.7.7.1 General corrosion. 4.7.7.1.1 Test specimens. The test specimens shall consist of the following metals, in accordance with UNS designations (see ASTM E527): G10100 steel, C7Q600 copper-nickel alloy, N04400 nickel-copper and C90500 bronze. All specimens, except the bronze, shall be milled to Finished dimensions of approximately 1/16 inch thick, 1/2 inch wide, and 3 inches long. The bronze shall have sand cast faces and be approximately 3/16 inch thick, 1/2 inch wide, and 3 inches long. All specimens shall be degreased in acetone, rinsed with distilled water, and air dried before exposure. (Prepared metal specimens may be obtained from the Metaspec Company, Box 27707, San Antonio, Texas 27227-0707.) 4.7.7.1.2 Test procedures. Five weighed specimens of each metal shall be fully immersed in the test medium in a separate 600 mL beaker and held at room temperature for a period of 60 days. A watch-glass cover shall be used to retard evaporation. At the end of the exposure period, the weight-loss shall be determined and the corrosion rate calculated as required. 4.7.7.2 Localized corrosion. 4.7.7.2.1 Test specimens. The test specimens shall consist of UNS S30400 CRES milled to finished dimensions of approximately 1/16 inch thick, 1/2 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 a period of 5 minutes. 4.7.7.2.2 Procedure. Ten specimens shall be girdled lengthwise with a clean 1/16 to 1/8 inch wide band of 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 12 US00005918 Downloaded from http://www.everyspec.com on 2011-05-03T15:11:47. MIL-F-24385F bands for this lest be cut from 1-3/4 inch flat width pure gum amber tubing (Preiser Scientific Rubber tubing, Pure Gum, Gooch type, 1/32-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 1/4-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. 4.7.7.2J 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 the 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. 4.7.8 Total halides. The halide content shall be determined to be in accordance with ASTM D1821, except for the following modifications: a. Procedure: (1) Weight 4 0.1 g or add 4 0.1 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). b. The calculation shall be modified as follows: Halide content, p/m = 44.4(A-B). 4.7.9 Dry chemical compatibility. The foam's compatibility with potassium bicarbonate dry chemical extinguishing agent shall be determined by measuring the burnback time in the presence of dry chemical. 4.7.9.1 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 A of RR-S-366. 4.7.9.2 Test procedure. A 28-square-foot fire test shall be conducted in accordance with 4.7.13.1 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 the aid of a sieve 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 be not 13 US00005919 Downloaded from http://www.everyspec.com on 2011-05-03T15:11:47. MIL-F-24385F longer than 90 seconds. The burnback time shall be determined as in 4.7.13.1.4. 4.7.10 Stability. 4.7.10.1 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 (L) of each shall be placed in lightly stoppered glass cylinders. All samples shall then be stored at 65 C 2.0 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 scalability d. Fire performance (28 ft2) e. Stratification f.
