shall meet the same requirements for deflection and structural adequacy as
specified for framing members when tested in accordance with ASTM E 330
except permanent deformation shall not exceed 0.4 percent; there shall be
no glass breakage, and no permanent damage to fasteners, anchors, hardware,
or operating devices. Windows shall have no water penetration when tested
in accordance with ASTM E 331.

Fire Resistance Tests
**************************************************************************
NOTE: The exception to the smoke developed
requirement as given in this paragraph does not
apply to hospitals and confinement (correctional)
facilities; insulation for these facilities must
have a smoke developed rating not exceeding 150.
**************************************************************************
Insulation [provided in the curtain wall system] [field applied in
conjunction with the curtain wall system] shall have a flame spread rating
not exceeding 75 and a smoke developed rating not exceeding 150 when tested
in accordance with ASTM E 84, except as specified otherwise herein.
a.
Insulation: Insulation [contained entirely within panel
assemblies which meets the flame spread and smoke developed
ratings of 75 and 150 respectively] [isolated from the building
interior by masonry walls, masonry cavity walls, or encased in
masonry cores] is not required to comply with the flame spread and
smoke developed ratings specified.
b.
Curtain Wall Systems: Material for firestopping the opening
between the edge of the floor slab and back of the curtain wall
system, shall have not less than the flame spread and smoke
developed ratings specified for insulation which is neither
isolated from the building interior nor encased in masonry cores.
c.
Curtain Wall Panels: Panels for fire resistive curtain walls
shall have a fire resistive rating of [_____] hours when tested in
accordance with ASTM E 119.
d.
Firestopping Materials and Devices: Firestopping material and
attachment devices shall be an effective barrier against the
spread of fire, smoke, and gases for a period of [_____] hours
when exposed to the conditions of the standard ASTM E 119
time-temperature curve for a period equivalent to the fire rating
of the floor system and shall also be rated noncombustible when
tested in accordance with ASTM E 136.
1.4.3.8
Sound Transmission Loss Test
Sound transmission loss (TL) of the wall shall be less than [_____] db,
when tested in accordance with ASTM E 90 for the frequency range from [125]
[_____] to [400] [_____] Hz.

GLAZED CURTAIN WALL SYSTEM REQUIREMENTS
**************************************************************************
NOTE: This specification is intended for use with
glazed curtain walls for low rise buildings and
multi-story buildings. Since aluminum shapes are
