Overview
This book represents the work of numerous authors at the first Symposium on the Use of
Glass in Buildings, April ,41 2002, Pittsburgh, .AP Architectural glass was the broad focus
for this symposium. Papers and presentations were targeted to deliver information the user
may find useful related to the quality, design, use, and performance of architectural glass.
The symposium had a broad focus that incorporated a variety of glass-related topics. Em-
phasis on glass design was also a key feature to the symposium.
The papers contained in this publication represent the commitment of the ASTM E-06.51
subcommittee to providing timely and comprehensive information on glass used in buildings.
Common themes throughout the tenure of this symposium can be found in this issue. Papers
discussing quality issues, performance assessments, glass design glass ni hurricane-prone
areas, and glass for fire safety and security were presented.
Quality Issues
Quality issues were addressed from several points of view. One paper focused on the
problems associated with the use of ASTM C1036 for field inspections of glass. Another
paper examined the interrelationship between building codes and glass standards. A third
paper discussed an on-line quality control measuring system for tempered and heat-
strengthened glass. A fourth paper assessed the impact of self-cleaning glass.
Performance Assessments
The intent of this section was to present developments around the performance of insu-
lating glass and glass facades. One paper discussed in-situ dew point testing to assess life
span of insulating glass units. A second presented an assessment of annual energy con-
sumption of ventilated double glass facades using computer simulation. A third paper focused
on the evaluation of a condensation resistance rating as determined using the National Fen-
estration Rating Council (NFRC) 500 procedure.
Glass Design
A series of papers were presented on glass design. One paper examined the structural
performance of laminated 'glass made with stiff interlayers. Several papers dealt with design
methodologies for glass, including rectangular window glass supported on three sides, large
trapezoidal window glass lites, and window glass design software based on ASTM El300.
Another paper introduced a new procedure for thermal stress evaluation of monolithic glass.
Glass in Hurricanes
Glass used in hurricane-prone areas requires special design consideration. In this session,
one speaker addressed retrofitting commercial structures with laminated glass to withstand
hurricane effects. A second paper discussed testing of annealed glass with anchored-film
glass retention systems.

viii THE USE OF GLASS IN BUILDINGS
Glass for Fire Safety and Security
This section was developed to cover a broad spectrum of topics, including security glazing,
fire rated glass and sprinklers, and a design procedure for blast resistant laminated glass.

Abstract: Glass can be damaged after installation, and often the home or building
owner is left trying to determine if the resulting surface damage is acceptable. Glass
quality is addressed in ASTM C1036, Standard Specification for Flat Glass. However,
this standard is not intended for use in the field. It is useful for the proper specification of
glass quality, and in lieu of any other field inspection standards, parts of ASTM C1036
are helpful in defining acceptable scratch criteria.
Keywords: damaged glass, scratched glass, glass inspection, glass specification, glass
storage
Introduction
Inspecting scratched glass in the field is far from an exact science. It is quite
common for the project specifications to overlook the type of scratches that are
acceptable. The owner and contractor are both exposed to risk in this situation. When a
project has damaged glass, the parties look for an industry quality standard, and often turn
to ASTM C1036, Standard Specification for Flat Glass to inspect the glass. Under ASTM
C1036, medium-intensity scratches are allowed for glass quality Glazing Select (Q3).
This level of quality is recommended for architectural applications including reflective
and low emissivity coated glass products, and other select glazing applications. It is the
most commonly specified quality of glass in the industry I and refers to Table 4 criteria
(Figure )1 for the maximum allowable blemishes for 6.0 mm (1/4 in.) or less glass
thickness.
