When specified (see 6.2) a sample shall be subjecte
17、d to first article inspection (see 6.3) in accordance with 4.3. 3.2 Standard sample. The finished cloth shall match the standard sample for shade and appearance and shall be equal to or better than the standard sample with respect to all characteristics for which the standard sample is referenced (s

The blend shall consist of 95 percent meta-aramid fiber and 5 percent para-aramid fiber. The fiber s
19、hall be 1.5 denier per filament, and 1-1/2 to 2 inches in staple length. The fiber shall not char at a tempera-ture less than 675OF. The yarn for both the warp and filling shall be spun into singles for the type I cloth and 2-ply or the type II cloth. 3.3.1.1 Conductive fiber. An approved conductive
20、 fiber (see 6.6) may be added to the aramid fiber blend to meet the electrostatic decay requirement as specified in 3.8,l. 3.4 Color. 3.4.1 Types I and II, class 6.

21、lored fiber (see 6.12). The color shall be 3.4.2 Type II, class 5. The cloth shall be colored to a ground shade either matching or approximating Light Green 354, and subsequently overprinted with the applicable camouflage pattern. When the ground shade is colored to match the Light Green 354, the wo
22、odland camouflage pattern shall be obtained by roller or screen printing using three rollers or screens, as appropriate for the Dark Green 355, Brown 356 and Black 357 areas of the pattern. If the ground shade is colored to approximate Light Green 354, four rollers or screens shall be used to match
23、the required pattern. 3.4.3 Visual matching. The color of the finished cloth, shall match the standard sample when viewed under filtered tungsten lamps that approximate artificial daylight and that have a correlated color temperature of 7500 + 200 Ky with illumination of 100 + 20 foot candles and sh
24、all be a good match to the standard sample under incandescent lamplight at 2300 2 200 K. 3.4.4 Instrumental matching, class 5. As an alternative to visual color matching the following instrumental color matching requirements may be used. The four colors in the Woodland pattern for the printed finish
25、ed cloth listed below shall match the corresponding colors in the standard sample when measured on a spectrophotometer (see 6.8) in the visible wavelength range of the electromagnetic spectrum, 400 to 700 nanometers (nm). The following are the maximum numerical tolerances for acceptability (AA) for
26、each of the four colors in the Woodland pattern when tested as specified in 4.5.2.

The finished cloth shall show fa
29、stness to crocking equal to or better than the standard sample or shall show and AATCC Chromatic Transference Scale rating not lower than 3.5 for each of the pattern areas except Black 357 which shall show and AATCC Chromatic Transference Scale rating not lower than 1.5. Testing shall be as specifie
30、d in 4.4.3. 3.5 Pattern execution, class 5. The pattern shall match the standard sample with respect to design, colors and registration of the respective areas. Each pattern area shall show solid coverage; skitter ness exceeding that shown by the standard sample in any of the printed areas wil not b
31、e acceptable. The pattern repeat of the camouflage printed finished cloth shall be 27.25 +1.25 -2.5 inches. When the standard sample is not availa le for pattern execution, a pattern drawing shall be provided, and the pattern on the finished cloth shall match that of the drawing (see 2.1.2 and 6.2).
