whichever is less, when tested in accordance with ASTM E 330, except that
when a plastered surface will be affected the deflection shall not exceed
1/360 of the span. No framing member shall have a permanent deformation in
excess of 0.2 percent of its clear span when tested in accordance with ASTM
E 330 for a minimum test period of 10 seconds at 1.5 times the design wind
pressures specified.
1.4.3.2
Water Penetration Test
**************************************************************************
NOTE: The test method of ASTM E 331 is that of
determining resistance of the curtain wall to water
penetration under uniform static air pressure
difference. When testing under dynamic conditions
is required, AAMA Specification 501 should be
referenced. The availability of facilities for
conducting dynamic testing is very limited and
should be checked before specifying this type of
test.
**************************************************************************
No water penetration shall occur when the wall is tested in accordance with
ASTM E 331 at a differential static test pressure of 20 percent of the
inward acting design wind pressure as specified, but not less than 0.19 kPa
4 psf. Make provision in the wall construction for adequate drainage to
the outside of water leakage or condensation that occurs within the outer
face of the wall. Leave drainage and weep openings in members and wall
open during test.
1.4.3.3
Air Infiltration Test
Air infiltration through the wall, when tested in accordance with ASTM E 283,
shall not exceed 0.005 cms per sq. m 0.06 cfm per square foot of fixed wall
area, plus the permissible allowance specified for operable windows within
the test area.
1.4.3.4
Delamination Test
Adhesively bonded metal-faced [[_____] faced] panels shall show no evidence
of delamination, warpage or other deterioration or damage when subjected to
the six "Accelerated Aging Cycles" specified in ASTM D 1037.
1.4.3.5
Thermal Conductance Tests
The thermal transmittance of opaque panels shall not exceed specified
U-value, when tested in accordance with ASTM C 236. The average calculated
thermal transmittance of the complete wall assembly including panels,
windows, and all other components shall not exceed a U-value of [_____].
Determine U-values of components in accordance with ASTM C 236.
1.4.3.6
Window Tests
**************************************************************************
NOTE: Inert appropriate Section number and title in
blank below using format per UFC 1-300-02.
**************************************************************************
Windows shall meet the requirements specified in [_____] except where the
requirements of this section differ, this section shall govern. Windows
