1. What is the primary purpose of blast resistant glazing in building
design?
A. To improve energy efficiency
B. To protect occupants and structures from explosive forces
C. To reduce noise transmission
D. To enhance aesthetic appeal
Blast resistant glazing is specifically designed to withstand blast
pressures and protect building occupants and structures from
explosive events.
2. Which standard is commonly referenced for determining blast load
design criteria?
A. ASTM E119
B. UFC 3-340-02
C. AAMA 101
D. NFPA 70
UFC 3-340-02 provides criteria for blast-resistant design of structures
and glazing systems.
,3. In blast resistant glazing nomenclature, the term “standoff distance”
refers to:
A. The thickness of the glass panel
B. The height of the frame above grade
C. The distance between the explosive and the window surface
D. The distance between mullions
Standoff distance is the separation between an explosive source and
the glazing surface, which influences blast pressure.
4. Which material property is most critical for glazing to absorb blast
energy?
A. Thermal conductivity
B. Optical clarity
C. Ductility
D. Hardness
Ductility allows the glazing material to deform without fracturing,
which helps absorb blast energy.
5. Laminated glass typically used in blast resistant applications contains:
A. A single layer of annealed glass
B. Tempered glass with no interlayer
C. Multiple glass plies bonded with polymer interlayers
D. Acrylic sheets only
Laminated glass combines two or more glass plies bonded with
interlayers to improve post-breakage performance.
6. In blast glazing, the “interlayer” refers to:
A. The metal frame around the glass
B. The polymer layer between glass plies
C. The glazing bead
D. The spacer in insulating glass
, The interlayer is a polymer film, typically PVB or polycarbonate, that
holds glass fragments together during failure.
7. How does tempered glass differ from laminated glass in blast
resistance?
A. It is stronger in compression
B. It has better thermal properties
C. It is cheaper
D. It is less effective at retaining fragments after breakage
Tempered glass offers higher strength but does not retain fragments
like laminated glass under blast conditions.
8. What is the role of the framing system in a blast resistant glazing
assembly?
A. To support and transfer blast loads to the structure
B. To provide decorative trim
C. To allow easy removal for cleaning
D. To insulate against heat transfer
The framing system must carry and distribute blast loads without
failure.
9. When installing blast resistant glazing, installers must ensure:
A. The color matches adjacent windows
B. Proper anchorage and sealant application
C. Glass is installed loosely
D. Only aesthetics are prioritized
Proper anchorage and correct sealant application are essential for
performance under blast loads.
10. The term “design pressure” in blast glazing refers to:
A. Atmospheric pressure
B. Wind load only
C. Pressure at sea level
