a) Traffic level (high or low).  This represents the
number of people working or moving through an area.
b) Exposure to extreme temperatures
c) Worksheets (see Appendix B):
1)  Cross-Section Selection (CSS)
2)  Cross-Section Evaluation (CSE)
<1> For Each Cross-Section: Do <2> through <5> for each cross-section on the
Cross-Section Selection or Cross-section Evaluation worksheet (see AppendB x
i
for all worksheets).  If this is an analysis for a selection application,
return to Figure 6.  Otherwise, return toFigure 7.
<2> Select Using Cross-Section Type: Select the next structure by type of cross-
section.  For a glass-clad polycarbonate cross-section, proceed to <3>.  For a
polycarbonate cross-section, proceed to <5>.  For a laminated glass cross-
section, proceed to <6>.
<3> Exposed to Extreme Low Temperatures? If cross-section is exposed to
temperatures of 0F or lower for at least 20% of the time, proceed to <4>.
Otherwise, proceed to <1> for next cross-section.
<4> Consider Air-Gap System. Consider using an air-gap system to avoid
temperature-induced stresses at the glass to polycarbonate interface.  Proceed
to <1> for next cross-section.
<5> Polycarbonate Environmental Analysis: Analyze environmental effects for a
polycarbonate cross-section using igure 32
F
.  Proceed to <1> for next cross-
section.
<6> Laminated Glass Environmental Analysis. Analyze environmental effects for a
laminated glass cross-section using igure 33
F
.  Proceed to <1> for next cross-
section.

Polycarbonate Environmental Analysis Procedure.  This
procedure covers high humidity, high traffic conditions, and
vandalism for polycarbonate.  Figure 32 presents a process chart
description for the polycarbonate environmental analysis
procedure.
8.3.1
Required Information.  The following information is
required for the polycarbonate environmental analysis procedure:
a) Traffic level (high or low).  This represents the
number of people working or moving through an area.
b) Humidity level (high or low)
c) Exposure to extreme temperatures
d) Worksheets (see Appendix B):
1)  None
