Stress applied to a specimen made by joiningtwo ends of the braided tape with a square knot shall result in the breakage of

11、 the tape specimen rather the slippageor pulling out of the knot when tested as specified in Paragraph 5.2.2. Knot slip resistance is not applicable totapes which have finish A, B, and E.3.8 Put-up. Unless otherwise specified, the tape shall be furnished on parallel wind spools (reels) oruniversal w

12、ind tubes (holders). Size 1 and 2 tapes shall be put-up in a minimum of 250 yard lengths, and size 3,4, and 5 tapes shall be put-up in a minimum of 500 yard lengths. The tape shall be free from twists, lumps, orprojecting ends and shall be evenly wound so that each turn and layer is free from entang

13、lement and twisting.There shall be no more than four pieces per reel or holder, and no piece shall be less than 50 yards in length.3.9 Breaking Strength. Minimum breaking strength shall be as stated in Table I when tested as specifiedin Fed-Std-191 Method 4108.3.10 Fungus Resistance. No tape shall s

There shall be no visible damage or removal of the coatings on finish C, and E tapeswhen tested as specified in Paragraph 5.2.3.3.12 Accelerated Agin

15、g. When specified (see 7.4), finish C, and E tapes shall show no evidence ofstiffness, brittleness, softness, or tackiness when tested as specified in Fed-Std-191 Method 5852, except that thespecimen shall be six inches in length by the full width of the tape.3.13 Identification. Tape shall be tagge

16、d with a label or ticket containing at least the followinginformation: CID part number, National Stock Number, date of manufacture, and manufacturers name. Whenput-up or color is non-standard, the tag shall indicate the actual color or length.4. REGULATORY REQUIREMENTS4.1 The offerer/contractor is e

17、ncouraged to use recovered materials to the maximum extent practicable, inaccordance with paragraph 23.403 of the Federal Acquisition Regulation (FAR).Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-52081B35. QUALITY ASSURANCE PROVISIONS.5.1 Prod

18、uct Conformance. The products provided shall meet the salient characteristics of thiscommercial item description, conform to the producers own drawings, specifications, standards, and qualityassurance practices and be the same product offered for sale in the commercial market. The government reserve

19、sthe right to require proof of such conformance5.2 Inspection Requirements5.2.1 Determination of Percentage of Finish. The percentage of finish B, C, and E impregnatingmaterials on the respective type tapes shall be determined during processing, by the manufacturer, by weighing anidentical sample of

20、 tape or yarn (see 3.6), before and after the impregnating process. The test specimen shall be aminimum of 30 yards of tape or 120 yards of yarn as applicable. Weight (Length per pound) shall be determinedin accordance with Method 4010 of FED- STD-191. The percentage of finish shall be calculated as

21、 follows:Percent Finish A-B x 100BWhere: A = Length per pound of untreated tape or yarn, as applicable.B = Length per pound of treated tape or yarn, as applicable.5.2.2 Determination of Knot Slip Resistance. The knot slip resistance of the tapes shall be determined byusing Fed-Std-191 Method 4108, e

22、xcept as modified herein. The test specimens shall be cut in half and then thetwo halves shall be firmly tied together with a square knot. The two protruding ends at the knot shall be cut so thatone-half inch protrudes. The specimen shall be aligned so that the knot is approximately halfway between

23、theclamps. The machine shall be operated until the knot slips or pulls out or the specimen breaks at or in proximity tothe knot. Breaks closer than 1/2 inch of the jaws shall be discarded. Five good readings shall be obtained. If knotslippage is obtained on only one of five readings, an additional s

24、pecimen shall be tested and if a good reading isobtained, the reading indicating knot slippage shall be discarded.5.2.3 Determination of Blocking. Ten turns of the tape shall be wound on a one-quarter inchdiameter clean metal mandrel under a two pound tension and the end secured through holes in the

25、 mandrel. Eightturns of tape shall then be wound on top of the first layer under the two pound tension and the ends secured asbefore. The wound mandrel shall then be placed in a temperature controlled oven at 70 + 1o C for two hours, andin such a manner that no part of the specimen comes in contact

26、with the surface of the oven. The specimen shallthen be removed and cooled at room temperature. After cooling, the outer layer shall be unwound and examinedfor evidence of damage to the coatings due to adhesion between layers of turns. The first layer shall be examinedwhile still in place for simila

27、r evidence of adherence and damage.6. PACKAGING.6.1 Preservation, packing, and marking shall be as specified in the contract or order.7. NOTES.7.1 Intended use. The tape is intended for lacing and tying electrical wire and cable bundles. Tape withfinish C provides the best knot holding characteristi

28、cs. Finish E may provide good resistance to fluids and fuels.Useful temperature range of polyester tape is -100 F to 280 F.Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-52081B47.2 Part Identification Number (PIN).
