22、nforced coating adhesion specimens, cyanoacrylate (solventless) adhesive, and pulling clamp speed of 5 ds. Three specimens shall be tested by adhering face-to face and three specimens shall be tested by adhering back-to-back. 4.4.7 Blocking;. - ASTM D-75 1, Determination of Blocking Resistance of Fa
23、brics Coated with Rubber or Plastics at Elevated Temperatures, except that only one specimen shall be exposed at an oven temperature of 180F k2“F for 30 minutes. 4.4.8 Resistance to leakage test . ASTM-D-75 1, Hydrostatic Resistance, Procedure B, (Pressure Application by a Rising Column of Water), P
24、rocedure 2 with the hydrostatic head fixed at 50 centimeters and applied to the test specimen for 10 minutes. The back side of the finished cloth shall contact the water. The report shall only include “measurement of the appearance of water drops“. Leakage of any specimen shall be considered a test
25、failure. Leakage is defined as the appearance of water at three or more different places within the 4 1/2 inch diameter test area. 4.4.9 Resistance to diethyltoluamide . The diethyltoluamide for use in this test shall conform to type It, concentration A of 0-1-503. Three drops of the diethyltoluamid
26、e solution shall be placed in the center of a 4 by 8- inch specimen of the finished cloth with the diethyltoluamide solution contacting the face side. The specimen shall be folded to form a 4 by 4-inch square with the face sides contacting each other. The folded specimen shall then be placed between
27、 two 6 by 6-inch glass plates and a 4-pound weight placed on the assembly and left at standard conditions for 16 hours. The specimen shall then be removed from between the glass plates, scale rated for blocking as shown in ASTM D-75 1, Determination of Blocking Resistance of Fabrics Coated with Rubb
28、er or Plastics at Elevated Temperatures, except that the specimen shall not be exposed to elevated temperature, and then immediately examined for conformance to the requirements in Table I. 4.4.10 Adhesion of seam tape . The test shall be conducted as follows: A heat seal tape, 1 inch (+ 1/16 inch)
29、wide shall be heat sealed to the back side of the finished cloth by activating the thermoplastic adhesive layer of the heat seal tape using high temperature air and then immediately plying the tape with the back side of the waterproof cloth (parallel to the warp direction of the waterproof cloth) ob
30、taining intimate contact between the tape and waterproof cloth by passing through pressurized rollers. The use of a flat-faced heated platen-type sealing machine is prohibited. Five specimens shall be prepared; no two specimens shall contain the same warp yarns. Test specimens shall be cooled and co
31、nditioned prior to testing for adhesion. The adhesion test shall be conducted in accordance with Method 5962 of FED- STD-191 except that the maximum load of resistance occurring in the 3-inch separation shall be recorded. 4.4.1 1 Color matching: . The color of the waterproof cloth shall match the st
32、andard sample when viewed under filtered tungsten lamps that approximate artificial daylight and that have a correlated color temperature of 7500 e.g., magnesium oxide, or vitrolite tiles. The spectral band width at 860 nm shall be less than 26 nm. Reflectance measurements shall be made by either th
33、e monochromatic or polychromatic mode of operation. When the polychromatic mode is used, the spectrophotometer shall operate with the specimen diffusely illuminated with the full emission of a continuous source that simulates either CIE Source A or CIE Source D65. The specimen shall be measured as a
34、 single layer backed with two layers of the same fabric and shade. Measurements shall be taken on a minimum of two different areas, and the data averaged. The measurement areas should be at least 6 inches away from the edges of the finished cloth. The specimen shall be viewed at an angle no greater
35、than 10“ from normal, with the specular component included. Photometric accuracy of the spectrophotometer shall be within 1 percent and wavelength accuracy within 2 nm. The standard aperture size used in the color measurement device shall be 1 .O to 1.25 inches in diameter. Any color having spectral
36、 reflectance values falling outside the limits at four or more of the wavelengths specified in 3.5.1 for Type I or in 3.5.2 for Type Ii shall be considered a test failure. 4.4.13 Pattern execution . The pattern on the waterproof cloth shall be matched to the pattern drawing (see 6.4). 4.4.14 Toxicit
37、y assessment . The waterproof cloth shall be tested for toxicity as follows: a) Title 40, Code of Federal Regulations, 1994 Edition; Section 798.4100- Dermal Sensitization Section 798.4470- Primary Dermal Irritation Section 798.4500- Primary Eye Initation Marzulli, F. & H.

For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When actual packaging of materiel is to be performed by DoD personnel, these
40、personnel need to contact the responsible packaging activity to ascertain requisite packaging requirements. Packaging requirements are maintained by the Inventory Control Points packaging activity within the Military Department System Command. Packaging data retrieval is available from the managing
