REQUIREMENTS: 3.1 First article inspection: Unless otherwise specified, the contractor shall furnish sample units for first article inspection and approval (see 4.4).3.2 Materials: The tape shall co
18、nsist of a backing coated on one side with a pressure sensitive adhesive requiring no moisture, heat or other special preparation prior to or after application.3.2.1 Backing: The backing shall be uniform in texture and shall perform satisfactorily as a masking tape. The backing shall have sufficient
19、 strength to allow the tape to be unwound from the roll and to be removed from the masked surface after application of finishing materials without breakage or delamination. The finishing materials shall not penetrate the backing.3.2.1.1 For type III: Surface of backing (not coated with adhesive) sha
20、ll have a matte finish to prevent paint flaking (flakeoff) during tape removal operation.3.2.2 Adhesive: The adhesive shall be pressure sensitive, water insoluble, homogeneous, and coated in a smooth and evenly distributed layer on one side of the backing. The adhesive shall cause the tape to adhere
21、 immediately and firmly to clean, dry surfaces to which the tape is generally applied during masking in finishing operations without wrinkling, curling, breaking or lifting. There shall be no liner over the adhesive.3.3 Finished tapes: 3.3.1 Rolls: The tape shall be uniformly and smoothly wound in r
22、olls, with adhesive side in, on suitable cores having an inside diameter of 3 (-0 + 1/16) inches. The cores shall have sufficient rigidity to prevent distortion of the roll under normal conditions of use. The tape shall be in one continuous strip, except that any single roll may contain three splice
23、s, provided the percentage of spliced rolls in any shipment does not exceed a reasonable proportion based upon standard manufacturing practice. The length of the tape in rolls shall be not less than 60 yards.3.3.2 Width: Tape widths shall be 1/2, 3/4, 1, 1-1/2, 2, 3-inches. Width tolerance of 1/32 i
24、nch applies to all types of tapes.3.3.3 Color: Tapes shall be opaque and may be any color commercially used by tape manufacturer.3.3.4 Marking of rolls: Each roll of tape shall be marked in or on the edge of the core with the manufacturers name and the specification number.3.4 Performance: Tapes sha
25、ll conform to the requirements of Table I.AMS-T-21595 SAE AMS-T-21595- 4 -3.5 Workmanship: The adhesive shall be a smooth, uniform coating covering the entire area of one side of the tape. Edges of the tape shall be straight, true and unbroken, to provide sharp, distinct boundaries to the finished (
26、painted) areas.TABLE I.
