4.5.1 Coated fabric. Coated fabric properties shall be tested in accordance with the test methods in table I. Nonconformance to 3.5.2 and table I shall constitute failure of this test.

4.5.2 Weathering resistance. During weather resistance testing, the exterior side of the berm liner sample shall face the light (see 6.4.6). The number of specimens shall be limited to 10 (5 in the warp direction and 5 in the fill direction). Testing shall be in accordance with ASTM D 750 or AATCC 111 as appropriate. Nonconformance with tables I shall constitute failure of this test.

4.5.3 Fungus resistance. The berm liner shall have no cracking, blistering or delamination and shall retain 60% of initial breaking strength when tested in accordance with

AATCC 30.

4.5.4 Low temperature crease resistance. Immerse three coated fabric specimens, each 8 inches square, in JP-8 conforming to 4.5.13, and condition for 24 hours, +1 hour, at 73 +5 °F.

Remove specimens, place on a wire screen, and air dry with forced air at 73 +5 °F, for 24 hours, +1 hour. Then, fold the specimens in half in each direction so that a folded corner occurs in the center of each specimen. Place each folded specimen under a 4-pound load and condition at -25 +2 °F (Type I) or -60 ±2 °F (Type II), for 46 hours. At the end of the conditioning period, unfold the specimens while still at test temperature and examine visually. Signs of cracking, peeling, or delamination of any coating material shall constitute failure of this test.

4.5.5 Blocking. Place three coated fabric specimens 6.00 inches by 1.00 inch on a smooth surface in such a manner that the ends are overlapped 1.00 inch. Place a 4-pound weight directly on the overlapped areas. Place prepared specimens in an oven. After conditioning at a temperature of 158 +2 °F, for 4 hours, take the specimens from the oven, remove the weight, and condition for 1 hour at 73 +5 °F and 65 +2 percent humidity. Attach one end of the specimen in a suitable clamping device, allowing the free end to hang down. Suspend a 4-ounce load from the free end of the specimens. Inability of the strips to separate within 5 seconds under the 4-ounce load shall constitute failure of this test.

4.5.6 Ozone resistance. Ozone resistance shall be tested as specified in ASTM D 1149.

Test method A specimen shall be conditioned for 7 days at a temperature of 104 ±4 °F in air having a partial pressure of ozone of 50 millipascals. Nonconformance to table I requirements shall constitute failure of the test.

4.5.7 Coating adhesion. Samples of coated fabric shall be bonded face-to-face to provide specimens for determining adhesion between the base fabric and exterior coating(s), between the base fabric and interior coating(s), between laminations of interior coatings and barrier, and between laminations of exterior coatings (see 6.4.5 and 6.4.6). In forming this bond the specimens shall be subjected to no heat or pressure other than that normally encountered in curing the coated fabric, except for minimal pressure necessary to ensure contact while the bond is setting.

4.5.7.1 Test procedure. The adhesion shall be determined in accordance with ASTM D 413, machine method, except that the specimens shall be 2 inches wide. The specimens shall be of sufficient length to conduct adhesion test for both initial values and after fuel (see 4.5.13) or water immersions. Immersion of specimens shall be in accordance with ASTM D 471. The adhesion results obtained on each immersed specimen shall be compared with the initial adhesion of the same specimen to determine percentage of adhesion retained. The reported adhesion and percent retention shall be the average of not less than three specimens. Attempts shall be made to cut the coating back to the fabric and to determine the adhesion value at the coating to fabric interface. However, if a specimen separates at a plane other than the bond of the coating to fabric (such as between layers of coating materials or between barrier film and coating) the adhesion value and the plane of failure shall be recorded. Immersed specimens shall be conditioned in the test fluid at 73 +5 °F, for 30 to 90 minutes before testing. Testing shall be completed within 3 minutes after removal from the conditioning fluid. Nonconformance to 3.5.2 and table I shall constitute failure of this test. Any obvious bond failure evident after immersion but before stressing, even if the plane of failure is not sandwiched between the layers of fabric, shall constitute failure of this test.

4.5.8 Puncture resistance. ASTM D 751 applies except that the ring clamp mechanism shall have an internal diameter of 3.00 inches. Nonconformance to 3.5.2 and table I shall constitute failure of this test.

4.5.9 Diffusion. The test apparatus shall consist of a diffusion cup and ring, using figure 2 as a guide. Other cup designs are acceptable as long as the inside diameter of the cup and ring is maintained at 2.000 inches ±0.016-inch and the cup is 1.00 inch ±0.06-inch deep. Cut a circular test disk of coated fabric to conform to the outside diameter of the cup flange. Punch holes in the disk to correspond to the flange bolt dimensions as needed. The cup shall be filled with approximately 40 ml of water. A suitable solution shall be used to seal the exposed fabric around the outer edge of the test disk and to seal the test disk to the diffusion cup flange. The test disk shall be placed over the cup with the berm liner "exterior" side towards the water (see 6.4.6). The bolts shall be tightened securely. Place the diffusion cup in a suitable rack that permits free access of air to the test disk and condition at constant temperature of 73.3 ±2 °F, and a relative humidity of 65 ±2 percent. Allow 1 hour for the assembly to reach equilibrium, then weigh the cup to the nearest 0.005 gram and place in the rack, face upward. Keep the cup at the above constant temperature and humidity for 24 hours, then weigh and check for vapor loss. Re-torque the bolts if necessary. Invert the cup (test disk down) in a rack to the test disk. Weigh the cup daily. Defective films or leaks caused by faulty assembly are usually found when the cup is weighed on the third day. Continue to weigh the cup daily until the weight loss is constant to within 0.010 grams per day after two 24 hour periods. Then record daily weight loss for a continuous interval of 72 hours. The diffusion rate (D) in fluid ounces per square foot per 24 hours shall be the average of not less than three specimens when calculated from the following expression:

D = 144 (average daily loss in grams) (Sp. Gr.) (29.573)(3.142)(R²)

Where Sp. Gr. is the specific gravity of the test medium and R² is the inside radius of the test cup.

4.5.10 Seam tests. The bonding together of any two or more pieces of coated fabric (such as lap joints, butt joints, coated fabric flanges of fittings, etc.) shall be considered seams and shall be subjected to all seam tests specified herein. The average breaking strength of five specimens for each type seam, for each test, shall be reported for conformance to table II.

Breaking strength specimens shall be 2.00 inches wide (parallel to the seam) and shall extend (perpendicular to the seam) 3.00 inches beyond both edges of the seam. Specimens shall be stabilized in the immersion fluids at 73 +5 °F, for 30 to 90 minutes before testing. Testing of immersed specimens shall be completed within 3 minutes after removal from the immersion fluids. The average peel adhesion strength of three specimens for each type seam shall be reported for conformance to table II. Peel adhesion specimens shall be of sufficient length to determine both the initial and after fuel (see 4.5.13) or water immersion values on the same specimen. If seam construction involves the use of binding thread, then the peel specimens shall be prepared with threads removed. All specimens shall break in the coated fabric. Failure of any specimen in a seam area shall constitute failure of this test. Nonconformance to 3.5.3 and table II shall constitute failure of this test.

4.5.11 Dead load shear resistance. The test specimens shall be 1.000 inch +0.020-inch wide, (parallel to the seam) and coated fabric shall extend a minimum of 3.00 inches (perpendicular to the seam) on each side of the seam. One index mark shall be scribed on each side of the seam to facilitate observation and measurement of slippage. Each specimen shall be subjected to a constant (dead load) tension force of 50 +0.50 pounds, at 180 +5 °F. After 8 hours examine each specimen while still under tension for sign of slippage or separation. Three specimens shall be tested for each determination. Slippage, by any specimen, greater than specified in table II shall constitute failure of this test.

4.5.12 Handle pull resistance. The test sample shall consist of the handle and a minimum of 1 foot of berm liner body fabric extending in all directions from the handle. The body fabric shall be tightly drawn and clamped. The rigidity, strength, and construction of the clamp(s) shall be such that the berm liner body material shall not slip more than 0.50 inch at any point during the test. With the sample held securely, a tension shall be applied by a bar or pipe, 1 inch in diameter, inserted in the loop of the handle. The tension shall be slowly and smoothly applied in a direction perpendicular to the edge and parallel to the plane of the berm liner until the specified load of 500 pounds is reached. The 500-pound load shall be maintained for 1 minute. Any damage, permanent distortion, or separation of the handle, or berm liner material shall constitute failure of this test.

4.5.13 Test fuel. Unless otherwise specified, each applicable test requirement shall utilize two sets of test specimens in parallel. Diesel fuel (A-A-52557) shall be used as the test fluid for the first set of test specimens and JP-8 (MIL-DTL-83133) shall be used for the second set.
