MIL-DTL-14072F
Dry Tape Test
Press a 5.08cm length of a somewhat longer piece of pressure sensitive adhesive tape
firmly on a flat or cylindrical surface of the item removing all air bubbles under the tape.
Allow the tape to normalize for 10 seconds. Grasp a free end of the tape and with a rapid
motion strip it from the test specimen by pulling the tape back upon itself at 180 degrees
(in such manner that the tape is folded back on itself during the procedure). Observe the
tested surface for areas where the paint is removed.
Disregard flecks of paint on the tape where the underlying metal, phosphate, chromate or
primer coating is not exposed.
Wet Tape Test
At the discretion of the Government, any or all of the following additional tests may be
performed:
A piece of cloth shall be taped on the area under inspection. The cloth shall be kept
soaked for a minimum of 24 hours with tap or distilled water. After 24 hours remove the
wet cloth and immediately apply a 5.08 cm length of pressure sensitive tape to the
painted surface, adhesive side down. Allow a sufficient additional length for gripping
with fingers during testing. Using finger/hand pressure press the 5.08 cm test section of
the tape firmly to the surface removing all air bubbles. Allow the tape to normalize for
10 seconds. In one abrupt motion remove the tape. Examine the tested area for damage
to the coating system or exposure of the base metal.
Scribe Tape Test
a. Scribe four 25.4mm lines completely through the paint finish, 1.59 to
2.38mm apart.
b. Scribe another four 25.4mm lines, 1.59 to 2.38mm apart, 90 degrees to
the first set of lines. The resulting pattern shall be nine squares.
c. Press a length of tape, longer than the scribed area, firmly over the
scribed pattern, rubbing out all air pockets.
d. Wait ten seconds minimum. Grasp a free end of the tape and at a rapid
speed strip it from the painted surface by pulling the tape back upon
itself at 180 degrees. The removal of two of more squares of topcoat,
topcoat primer, or topcoat primer-pretreatment coating constitutes test
failure. Removal of overspray does not constitute test failure.
Tape type.
The tape used for tape testing shall be 2.54 cm wide and have a minimum adhesion rating
of 502 g/cm.
