[0.10] [0.18] [0.25] mm [0.004] [0.007] [0.010] inch and shall be [clear]
[tinted] [reflective]. The film shall be supplied with an optically clear
weatherable pressure sensitive adhesive. The adhesive shall contain
ultraviolet inhibitors to protect the film for its required life and shall
limit ultraviolet transmission to not more than 8 percent of the radiation
between 300 and 380 nanometers. The adhesive shall not be water activated.
A water soluble detackifier and/or release liner may be incorporated over
the adhesive to facilitate film application. The adhesive shall be 90
percent cured within 30 days of installation. Adhesives on film
thicknesses of 0.25 mm 0.010 and greater shall be a minimum of 0.02 mm
0.0008 inch thick. The following tests to indicate compliance with
specified requirements shall be performed by an independent testing
laboratory, and the laboratory reports shall be signed by a responsible
official of the laboratory.
2.2.1
Impact Performance
**************************************************************************
NOTE: Retain sentences about splices when the film
will be applied to sheets of glass with a dimension
exceeding 1475 mm (58 inches) in both directions.
Paragraph 5.1.3 (2) of ANSI Z97.1 and paragraph
1204.4 (e) (1) (ii) of 16 CFR 1201 will not be an
accepted form of testing glazing failure after the
impact test because these paragraphs allow complete
disintegration if fragment particles are small
enough. Complete disintegration of the glazing is
unacceptable under blast loading because the
particles would be propelled into the building and
could seriously injure or kill the occupants.
Designers specifying fragment retention film for use
in other countries may substitute impact test
reports in accordance with British Standard (BS) BS
6206 Class B and German Standard DIN 5237, which use
similar testing methods to the impact tests
specified. The designer should accept but not
specify films tested and receiving an A1 impact
resistance under DIN 52290 or film which has tested
positively in accordance with BS 5544. Do not
specify the film to be tested in accordance with DIN
52290 or BS 5544 because relatively few films can
pass these more stringent impact tests.
**************************************************************************
Fragment retention film shall be tested for impact in accordance with ANSI
Z97.1 or 16 CFR 1201. Tests shall be conducted on fragment retention film
applied to 3.1 to 6.4 mm1/8 to 1/4 inch-thick annealed flat glass which
conforms to the requirements of ASTM C 1036, Type I, Class 1, Quality q3.
The film tested shall be applied to the glass with a splice located at the
midpoint of the specimen. Sketches showing location and configuration of
splice shall be included in submitted certified test reports. After the
impact portion of the test is conducted, satisfactory performance of the
test specimens shall be determined using ANSI Z97.1, paragraph 5.1.3 or 16
CFR 1201, paragraph 1201.4 (e)--INTERPRETATION OF RESULTS. To be qualified
for use under this specification, the manufacturer shall provide a report
that the fragment retention film satisfactorily performed in accordance
with ANSI Z97.1, paragraph 5.1.3 (1), (3), or (4) or with 16 CFR 1201,
paragraph 1204.4 (e) (1) (i), (iv), or (v). ANSI Z97.1, paragraph 5.1.3
