In the event of a conflict between the text of this document and the references cited herein, the text of this document takes precedence. Nothing in this document, however, supersedes applicable laws and regul

25、ations unless a specific exemption has been obtained. 3. REQUIREMENTS 3.1 First article. When specified (see 6.2), a sample shall be subjected to first article inspection (see 4.2 and 6.3). 3.2 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally pref

26、erable materials should be used to the maximum extent possible provided that the material meets or exceeds the operational and maintenance requirements, and promotes economically advantageous life cycle costs. 3.3 Design. The helmet cover is reversible and can be worn in both desert and woodland env

27、ironments. The Type I cover is designed to fit over the Marine Corps Lightweight Helmet, and the Personnel Armor System, Ground Troops (PASGT) helmet. The Type II cover is designed to fit over the Modular Integrated Communications Helmet (MICH), with front and back openings, and crown loop fastener

28、tape to accommodate communications equipment. See Figures 1 and 2. The cover provides the helmet with signature reduction in the visible and near infrared spectral ranges, which provides against detection by visual observation or through passive night vision devices. The cover also provides noise re

29、duction (softening noise if helmet strikes something). The cover contains buttonholes that allow for the attachment of indigenous plant material and other camouflage enhancing aids. 3.4 Basic material. The basic material for the reversible helmet cover shall be midweight nylon/cotton twill cloth pri

30、nted with a desert pattern print on the face side and the woodland pattern print on the back side, and conforming to the requirements specified below. The cloth shall show no toxicity when used as intended and when tested as specified in 4.4.1 (see 6.2e). The suggested sole source shall be in accord

31、ance with 6.6. 3.4.1 Nylon. The nylon shall be first quality, high tenacity, semi-dull staple having a nominal cut length of 1-1/2 inches and a round cross-section, with a nominal denier of 2.25 to 2.5. The use of any form of nylon waste is prohibited, such as undrawn fiber, mixtures of deniers, lus

32、ters or cross sections, and waste from any stage of fiber production: whether drawn, undrawn, or mixed or garneted fiber. The contractor shall submit the fiber producers certification that each lot nylon staple used conforms to the requirements specified herein. Testing shall be as specified in para

33、graph 4.4.2. 3.4.2 Cotton. The cotton shall be carded. Testing shall be as specified in paragraph 4.4.2. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-32117A 5 3.4.3 Yarn. The warp and filling yarn shall be singles made from a blend of 50 (

34、+ 5) percent nylon with the remaining percentage cotton, based on the dry weight of the desized cloth when tested as specified in paragraph 4.4.2. 3.4.4 Weave. The weave shall be a 2/1 left-hand twill. 3.4.5 Fiber and fabric identification. Each roll of finished cloth shall be labeled or ticketed fo

35、r fiber content in accordance with the Rules and Regulations under the Textile Fiber Products Identification Act. Each roll shall indicate cloth type. Testing shall be as specified in paragraph 4.4.2. 3.4.6 Physical requirements. The cloth shall conform to the requirements in Table I when tested as

37、 25.0 3.4.7 Color. The cloth shall be dyed and printed on the backside of the fabric with the woodland colors. The use of pigments may be allowed. The cloth shall be dyed to a ground shade approximating Khaki 475. The Woodland camouflage pattern shall be obtained by roller or screen-printing using e

38、ither three or four rollers or screens, as appropriate for the Green 474, Khaki 475, Coyote 476 and Black 477 areas of the pattern. The cloth shall be dyed and printed on the face side with the desert colors. The cloth shall be dyed and printed with the warp effect side as the face. The cloth shall

39、be dyed to a ground shade approximating Light Tan 479. The desert camouflage pattern shall be obtained by roller or screen-printing using either three or four rollers or screens, as appropriate for the Urban Tan 478, Light Tan 479, Highland 480 and Light Coyote 481 areas of the pattern. Resin bonded

40、 pigments are not permitted. 3.4.8 Labile sulfur. The use of dyes and compounds containing sulfur capable of oxidation to sulfuric acid shall be chosen and applied such that the dyed cloth shall contain no more labile sulfur than shown by the standard sample when tested as specified in 4.4.6. When n

41、o standard sample is available, the dyed cloth shall show no more than a slight trace of labile sulfur when tested as specified in 4.4.2. 3.4.9 Color matching 3.4.9.1 Visual matching. The color and appearance of the camouflage printed cloth shall match the standard sample when viewed using AATCC Eva

42、luation Procedure 9, Option A, under filtered tungsten lamps that approximate artificial daylight D75 illuminant with a color temperature of 7500 (+ 200) K with illumination of 100 (+ 20) foot candles, and shall be a good match to the standard sample under horizon lamplight at 2300 (+ 200) K. 3.4.9.

43、2 Instrumental color matching. Each color of the camouflage printed cloth shall match the standard sample using AATCC Evaluation Procedure 6. A color difference greater than a E CMC = 1.0 when using a E CMC (2:1) ratio (D65 /10O) units as compared to the standard sample, shall be basis for rejection

44、. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-32117A 6 3.4.10 Colorfastness. The finished camouflage printed cloth shall show fastness to: light (after 40 AATCC standard fading hours or 170 Kilojoules); laundering (after 4 cycles); and pe

45、rspiration (acid and alkaline) and crocking. The colorfastness of the cloth shall be equal to or better than the standard sample, or equal to or better than a rating of “4” using the AATCC Gray Scale for Color Change and a rating of “3-4” using the AATCC Gray Scale for Staining for each of the color

46、s, except the Black 477 shall have an equal to or better than a rating of 2-3. The woodland pattern print shall have a colorfastness to crocking rating when using the AATCC Chromatic Transference Scale Rating equal to or better than 3.0 for all colors except Black 477, which shall have a rating not

47、lower then, 1.0 when tested as specified in 4.4.2. 3.4.11 Pattern execution. The pattern shall reproduce the standard sample in respect to design, colors, and registration of the respective areas.
