The percentage of finish C impregnating materials on the respective type tapes shall be determined during processing, by the manufacturer, by w

18、eighing an identical sample of tape or yarn (see 3.6), before and after the impregnating process. The test specimen shall be a minimum of 30 yards of tape or 120 yards of yarn as applicable. Weight (Length per pound) shall be determined in accordance with Method 4010 of FED- STD-191. The percentage

19、of finish shall be calculated as follows: Percent Finish A-B x 100 A Where: 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 Deleted. 5.2.3 Determination of blocking. Ten turns of the tape shall be wound on a one-quarte

20、r inch diameter clean metal mandrel under a two pound tension and the end secured through holes in the mandrel. Eight turns of tape shall then be wound on top of the first layer under the two pound tension and the ends secured as before. The wound mandrel shall then be placed in a temperature contro

21、lled oven at 70 1o C for two hours, and in such a manner that no part of the specimen comes in contact with the surface of the oven. The specimen shall then be removed and cooled at room temperature. After cooling, the outer layer shall be unwound and examined for evidence of damage to the coatings

22、due to adhesion between layers of turns. The first layer shall be examined while still in place for similar 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 lacin

23、g and tying electrical wire and cable bundles. Tape with finish C provides the best knot holding characteristics. TFE-fluorocarbon may provide good resistance to fluids and fuels. Useful temperature range of TFE-fluorocarbon tape is -100 F to 450 F. 7.2 Part Identification Number (PIN). The PIN shal
