Knot slip

12、 resistance is notapplicable to tapes which have finish A, B or E.3.8 Put-up. Unless otherwise specified, the tape shall be furnished on parallel wind spools (reels) oruniversal wind 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

13、 be put-up in a minimum of 500 yard lengths.

REGULATORY REQUIREMENTS.4.1 The offerer/contractor is encourage

18、d to use recovered materials to the maximum extent practicable, inaccordance with paragraph 23.403 of the Federal Acquisition Regulation (FAR).5. QUALITY ASSURANCE PROVISIONS.5.1 Product Conformance. The products provided shall meet the salient characteristics of thiscommercial item description, con

19、form to the producers own drawings, specifications, standards, and qualityassurance practices and be the same product offered for sale in the commercial market. The government reservesthe right to require proof of such conformance5.2 Inspection Requirements5.2.1 Determination of Percentage of Finish

20、. The percentage of finish B, C, E and G impregnatingmaterials on the respective type tapes shall be determined during processing, by the manufacturer, by weighing anidentical sample of tape or yarn (see 3.6), before and after the impregnating process. The test specimen shall be aminimum of 30 yards

21、 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 follows:Percent Finish A-B x 100BWhere: A = Length per pound of untreated tape or yarn, as applicable.B = Length p

22、er 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 inaccordance with Fed-Std-191 Method 4108, except as modified herein. The test specimens shall be cut in half andthen the two halves shall be firmly

23、tied together with a square knot. The two protruding ends at the knot shall becut so that one-half inch protrudes. The specimen shall be aligned so that the knot is approximately halfwaybetween the clamps. The machine shall be operated until the knot slips or pulls out or the specimen breaks at or i

24、nproximity to the knot. Breaks closer than 1/2 inch of the jaws shall be discarded. Five good readings shall beobtained. If knot slippage is obtained on only one of five readings, an additional specimen shall be tested and if agood reading is obtained, the reading indicating knot slippage shall be d

25、iscarded.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 mandrel. Eightturns of tape shall then be wound on top of the first layer under the two pound tension an

26、d 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 with the surface of the oven. The specimen shallthen be removed and cooled at room temperature. After coo

27、ling, 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 similar evidence of adherence and damage.6. PACKAGING.6.1 Preservation, packing and marking shall be as specifi

The tape is intended for lacing and tying electrical wire and cable bundles. Tape withfinish C provides the best knot holding characteri

29、stics. Finishes E or G may provide good resistance to fluids andfuels. Useful temperature range of nylon tape is approximately -67 F to 250 F.7.2 Part Identification Number (PIN). The PIN shall consist of the basic CID number, followed by thefinish code letter from 3.6, followed by the size number f
