Unless otherwise noted herein or in the contract, 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, super
20、sedes applicable laws and regulations unless a specific exemption has been obtained. 3. REQUIREMENTS 3.1 Materials. 3.1.1 Yarn material composition. The yarn used in the manufacture of the tape shall be composed of non-recycled Nylon 6,6 fibers. The Nylon 6,6 fibers shall have a tenacity of 8.7 gram
21、s per denier minimum. The Nylon 6,6 fibers shall be polyamide prepared from a process using hexamethylene diamine and adipic acid, or its derivatives, and shall have a minimum melting point of 244 C (see 6.2h and 6.5). This requirement is not applicable to the manufacturers colored identification ya
22、rns. 3.1.1.1 Yarn fibers. The yarn fibers shall be free from sizing, loading, delustrants, or other adulterants, and shall not be bleached or pre-dyed in any manner or by any process (see 6.2h and 6.5). This requirement is not applicable to the manufacturers colored identification yarns. 3.1.1.2 Bri
23、ghtness. The yarn shall be described as “bright” or “super bright.” The brightness description of the polymer indicates that the polymer has not been “delustered.” A yarn fiber containing no more than 0.025 percent Titanium dioxide (TiO2) can be characterized as bright or super bright (see 6.2h and
24、6.5). This requirement is not applicable to the manufacturers colored identification yarns. 3.1.1.3 Heat and light resistance. The Nylon 6,6 polymer formulation shall provide protection from damage caused by exposure to heat and ultraviolet (sun) light (see 6.2h and 6.5). This requirement is not app
25、licable to the manufacturers colored identification yarns. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-81736B(AS) 5 3.1.1.4 Adulterants. The Nylon fiber and yarn shall be free of any chemicals specifically used to increase fiber or yarn d
26、iameters (see 6.2h and 6.5). This requirement is not applicable to the manufacturers colored identification yarns 3.1.1.5 Yarn properties. The yarn shall meet the physical property requirements of table I when tested as specified in table III (see 6.2h and 6.5). This requirement is not applicable to
27、 the manufacturers colored identification yarns. TABLE I. Nylon 6,6 yarn physical properties.

29、Unplied Yarns, Condition 1 Ambient Air (see 6.2h, 6.5 and 6.6). Each manufacturer whose yarn is used in arresting tape production shall meet this requirement. This requirement is not applicable to the manufacturers colored identification yarns. 3.1.1.7 Yarn size and ply. Yarns of different denier or
30、 ply shall not be intermixed within the binder, stuffer, or ground components of the tape. The stuffer and ground shall have the same denier and ply; however, the denier and ply may vary among the binder and ground (see 6.2h and 6.5). For example: the specification permits the use of 840 or 1260 den
31、ier yarn for the ground; using both deniers within the ground is not permitted; however, 840 denier yarn can be used for the binder and 1260 for the ground. This requirement is not applicable to the manufacturers colored identification yarns. Provided by IHSNot for ResaleNo reproduction or networkin

The tape shall be installed on a reel as shown on the applicable NAEC Drawing 506733, 613516, or 510534. 3.5.2.1 Tape installation procedure. When installing tape on reel, it shall be installed over barrier material conforming to MIL-PRF-131
40、, class 1 which has been wrapped around the periphery of the reel hub. The barrier material shall also cover the sides of the tape reel (inside of the shipping reel) with two additional feet of paper in excess of the reel side diameters to permit sealing two sides together all around the reel (see f
41、igure 2). The additional barrier material shall permit the opening and re-sealing of the barrier paper if examination of or work on the tape is required. Sealing process for barrier material shall not injure the tape. After installing the tape on reel and covering the barrier material, wooden cleats
42、 shall be installed around the edge of the reel, as shown on the applicable NAEC Drawing 506733, 613516, or 510534. FIGURE 2. Barrier material placement on reel.

46、as “Fair” or “Good” when tested as specified in 4.5. 3.7 Fiber identification. Each roll of tape shall be labeled, ticketed, or invoiced for fiber content in accordance with 16 CFR Part 303. 3.8 Resin treatment of tape. The tape shall be impregnated with resin Spraylat TR-5418-3 or equivalent as app
