REOUIREMENTS 3.1 Construction. 3.1.1 Type I tape shall consist of a polyester film, coated on one side with a homogeneous pressure-sensitive tape adhesive containing longitudinal reinforcing filaments. The reinf
12、orcing filaments shall be imbedded in the adhesive in a uniform layer throughout the length of the tape. The tape shall require no heat, solvent, or other preparation prior to or after applica- tion, and shall remove from the fiber containers or cans without breaking, over a temperature range of -66
13、O to 155OF (-53.3O to 68.3OC). 3.1.2 Type II tape shall consist of a biaxually oriented polypropylene Film coated on one side with a homogeneous pressure-sensitive adhesive in a uniform layer throughout the length of the tape. The tape shall not require any preparation prior to or after application,
14、 and shall remove from the fiber containers or cans without breaking over the temperature range of -66O to 155OF (-53.3O to 68.3OC). 3.2 Rolls. The tape shall be uniformly and evenly wound in - rolls, adhesive side in, on a core of sufficient rigidity to prevent distortion of the roll under conditio
15、ns of testing, transportation, storage and use. The inside diameter of the core shall be 3 .(-O, t 1/16) inches. 3.2.1 Length. Type I shall be furnished in 60 or 240 yard rolls as specified. Type II tape shall be furnished in 60 or 500 yards rolls, as specified. Each roll shall consist of a continuo
16、us length of tape, except that any single 60 yard roll shall contain no more than three splices, and 240 and 500 yard rolls shall contain no more than eight splices. The splices shall be made in such a manner that they will not separate when the roll is unwound for inspection or during machine or ha
17、nd applic-at ion. 3.2.2 Width. The width of the rolls shall be 1, 1 1/2 inches, or other commercially available width as specified. A tolerance of t 1/32 inch shall be allowed. - - 3.2.3 Color.

The adhesive shall cause the tape to adhere immediately, uniformly, and firmly to clean, dry surfaces when applied at any temperature within the range of 500 to 155OF (loo to 68.3OC) . 3.5 Holdinuower. The tape specimens with a one-inch acea and a 100
21、0 gram load adhered to a steel test panel, shall ehow no visual evidence of creepage in excess of 1/8 inch with the time interval specified in Table I, when tested as specified in 4.5.6. 3.6 Unwindaoperties. When tested as specified in 4.5.7, the tape shall meet the aiplicable requirements of Table
22、1, in the as-received condition-and after accelerated aging. The tape shall not break, nor shall the adhesive transfer to the back of the adjacent layer of tape so as to be visually evident during unwinaing o the tape a8 received, or after accelerated aging, 3.7 Ctabilit . The tape shall pass the ac

The tape shall not exhibit sufficient adhesive flow to the sides OE the rolls as to cause edge bond to be visually evident between the mcc
24、essive layers of the tape rolla. ( Such edge bond would be discernible in unwinding of the rolls (see 4.5.7). The tape shall show no visual a fiber containers or cans. The tape, d in 4.5.11, shall show no evidence of buckling, curling or lifting extending toward the center of the tape plies more tha
25、n 1/4 of the width of the tape from either side, and shall remove from the container without breaking. Adhesive transfer to the container or can shall not be cause for rejection. 3.8 LOW t . The tape shall be removable from the conta t breaking the tape backing, when tested as specified in 4.5.12. m

Each roll of tape shall be marked in or at the edge of the core with the
28、manufacturers name and code designation and (full or coded) date of manufacture. - 3.12 First-aicle-inRe. This specification contains provisions for first article inspection. Requirements for the submission of first article samples by the contractor shall be as specified in the contract (see 6.2). 3
29、.13 -_u- Workmansh&. The tape shall be fabricated in a thorough, workmanlike manner. It shall be free of foreign matter, and defects that detract from its appearance or that may impair its serviceability. The adhesive shall be a smooth uniform coating, evenly applied, covering the entire area of the
30、 backing without any bare spots or lumps. The tape shall be securely laminated, have no layer separation nor presence of blisters (applicable to reinforced tapes only). There shall be no holes, tears, cuts, cracks, or sharp creases. The edges of the tape shall be straight, clean cut, unbroken and no
31、t sticky. There shall not be any telescoping of the roll. TABLE I.
