this paragraph to hide the film edge.
**************************************************************************
Fragment retention film shall be applied past the edge of the visible glass
and extend onto the frame. Amount of film overlap, edge connection to the
frame, and adhesive for adhering film to frame shall be as recommended by
the film manufacturer. When contact between the glazing compounds and/or
gaskets and the film occurs, the Contractor shall ensure compatibility.
3.2.5
Splicing
**************************************************************************
NOTE: Overlaps of 0.25 mm (0.010 inch) thick and
thicker film are highly visible and are not
recommended. If no glazing has a dimension
exceeding 1475 mm (58 inches) in both directions,
specify that the film may not be spliced.
**************************************************************************
[Splices or seams in fragment retention film are not permitted.] [Splices
or seams in fragment retention film are permitted only when a sheet of
glass has a dimension exceeding 1.475 m 58 inches in both directions. All
seams shall be applied with a minimum overlap of 6 mm 1/4 inch unless
submitted test reports indicate impact performance is not diminished when
seam is applied with a different overlap or a gap.]
3.3
CLEANING
Cleaning of the fragment retention film shall be in accordance with the
manufacturer's instructions.
3.4
FIELD INSPECTION
The applied fragment retention film shall be clean and free of peeling,
splitting, scratches, creases, wrinkles, discoloration, and foreign
particles. The film application shall be free of air bubbles after 30
days. Fragment retention film shall not show signs of waviness and
distortion at the time the work is accepted. This determination shall be
made by the unaided eye (except for corrective prescription glasses), when
the film is viewed from a distance of 3 m 10 feet from the interior room
side at angles up to 45 degrees when looking at a clear or uniformly
overcast sky. Unacceptable fragment retention film applications shall be
removed in accordance with manufacturer's instructions and new film applied.
