A.
Serialization: Provide unique serial umber to be used for unit identification throughout
certification process and for historical archive of unit performance.
B.
Liquid Crystal Film Inspection Parameters:
1.
2.
3.
4.
C.
Visual Inspection: Inspect on a light table prior to placing into production.
ITO Resistance Verification: The conductive coating where electrodes are applied is
verified to be within the desired operating range before the material is used in production.
High Voltage Test: The film is tested for a short duration 130 percent of the normal
operating voltage to check for issues that would otherwise result in premature failure.
Dimensional Verification: Prior to lamination, log and verify that the dimensions of the
film are within defined tolerance.
Assembled Unit QC Inspection Parameters:
1.
2.
Cycle Test: Cycle each piece of glass 10,000 times to ensure proper switching.
Burn-in Test:
a.
b.
3.
Energize each piece of glass at a specified operating voltage for minimum of 24
hours.
Measure and verify the temperature of the glass at the end of the burn-in test to
ensure that it falls within an acceptable range.
Visual Inspection: inspect the glass with and without power for operation and defects.

Haze: Take and record haze measurements every 20 inches (508 mm) along each panel.
Light Transmission: Take and record light transmission measurements every 20 inches
(508 mm) along each panel.
Clarity" Take and record clarity measurements every 20 inches (508 mm) along each
panel.
Resistance: Take and record a resistance measurement across glass leads.
Operating Current: Measure, record, and verify the panel's operating voltage and current
draw. Ensure that current measured falls within the specified voltage range necessary for
the panel's size.
Insulation Resistance test: Test the insulation of the finished panel at 1440 V to ensure
the glass does not pose a shock hazard.
Verify Dimensions: Completed panel dimensions to be within 1/16 inch (1.6 mm) of the
specified dimensions.
SGCC Testing: Perform weekly sample tests to ensure that laminate performs according
to safety guidelines.
SPG Certification:
1.
Verify that measured values from previous stages of QC comply with standards set forth
in SPG Certification Standards.
PART 3 - EXECUTION
3.1
EXAMINATION
A.
Examine decorative-glass framing members, with Installer present, for compliance with the
following:
1.
2.
3.
B.
For switchable glass, verify the following conditions:
1.
2.
C.
3.2
Manufacturing and installation tolerances, including those for size, squareness, and
offsets at corners.
Minimum required face or edge clearances.
Effective sealing between joints of decorative-glass framing members.
Ensure that [glazing channels] [storefront framing] [doors] [windows] to receive
switchable glass are erected, secured, and prepared in accordance with Contract
Documents.
Verify wiring paths are prepared and clear.
Proceed with installation only after unsatisfactory conditions have been corrected.
PREPARATION
A.
Clean glazing channels and other framing members receiving glass immediately before glazing.
Remove coatings not firmly bonded to substrates.

Examine glazing units to locate orientation of outer surfaces[ as indicated on Drawings]. Label
or mark units as needed so that surface orientation is readily identifiable. Do not use materials
that leave visible marks in the completed Work.
INSTALLATION, GENERAL
A.
Set decorative-glass units in each series true in line with uniform orientation, pattern, draw,
bow, and similar characteristics.
B.
Set glass lites with proper orientation so that each outer surface faces the direction [indicated
on Drawings] <Insert orientation>.
C.
Set decorative glass in locations indicated on Drawings. Install glass with hardware and
accessories according to hardware manufacturer's written instructions. Attach hardware securely
to mounting surfaces[ and building structure].
D.
Set decorative glass in locations indicated on Drawings and as specified in <Insert Section
number and title>.
3.4
INSTALLATION OF SWITCHABLE GLASS
A.
Glazing: Comply with "Sealant Glazing (Wet) Article instructions and manufacturer's written
instructions.
B.
Wiring: Comply with Division 26 requirements, Electrical Drawings, and manufacturer's
written instructions. Exercise caution to prevent excess voltage applied to glass.
C.
Joints: Space joints straight. Avoid glass-to-glass contact.
D.
Butt Joints: Seal butt joints according to GANA "Glazing Manual".
3.5
GLAZING, GENERAL
A.
Decorative Glass: Install glazing as specified in Section 088000 "Glazing."
B.
Comply with combined written instructions of manufacturers of glass, gaskets, sealants, tapes,
and other glazing materials unless more stringent requirements are indicated, including those in
referenced glazing publications.
C.
Protect glass edges from damage during handling and installation. Remove damaged glass from
Project site and legally dispose of off Project site. Damaged glass is glass with edge damage or
other imperfections that, when installed, could weaken glass and impair performance and
appearance.
D.
Apply primers to joint surfaces where required for adhesion of sealants, as determined by
preconstruction testing.

E.
Install setting blocks in sill rabbets, sized and located to comply with referenced glazing
publications, unless otherwise required by glass manufacturer. Set blocks in thin course of
compatible sealant suitable for heel bead.
F.
Do not exceed edge pressures stipulated by glass manufacturers for installing glass lites.
G.
Provide spacers for glass lites where length plus width is more than 50 inches (1270 mm).
1.
2.
H.
3.6
Locate spacers directly opposite each other on both inside and outside faces of glass.
Install correct size and spacing to preserve required face clearances, unless gaskets and
glazing tapes are used that have demonstrated ability to maintain required face
clearances, and to comply with system performance requirements.
Provide 1/8-inch- (3-mm-) minimum bite of spacers on glass and use thickness equal to
sealant width. With glazing tape, use thickness slightly less than final compressed
thickness of tape.
Provide edge blocking where indicated or needed to prevent glass lites from moving sideways
in glazing channel, as recommended in writing by glass manufacturer and according to
requirements in referenced glazing publications.
SEALANT GLAZING (WET)
A.
Install continuous spacers, or spacers combined with cylindrical sealant backing, between glass
lites and glazing stops to maintain glass face clearances and to prevent sealant from extruding
into glass channel and blocking weep systems until sealants cure. Secure spacers or spacers and
backings in place and in position to control depth of installed sealant relative to edge clearance
for optimum sealant performance.
B.
Force sealants into glazing channels[ and between glass-to-glass joints] to eliminate voids and
to ensure complete wetting or bond of sealant to glass and channel surfaces.
C.
Tool exposed surfaces of sealants smooth.
3.7
CLEANING AND PROTECTION
A.
Immediately after installation, remove nonpermanent labels and clean surfaces.
B.
Protect glass from contact with contaminating substances resulting from construction
operations. If, despite such protection, contaminating substances do come into contact with
glass, remove substances immediately as recommended in writing by glass manufacturer.
C.
Remove and replace glass that is damaged during construction period.
D.
Wash glass on both exposed surfaces not more than four days before date scheduled for
inspections that establish date of Substantial Completion. Wash glass as recommended in
writing by glass manufacturer.
