1. According to ASTM C1048, what is the minimum required surface compression for fully
tempered glass?
A. 10,000 psi
B. 7,500 psi
C. 3,500 psi
D. 15,000 psi
Answer: A
Conceptual Explanation: Fully tempered glass must have a surface compression of 10,000
psi or greater, or an edge compression of 9,700 psi or greater, to meet safety standards.
2. In the High Velocity Hurricane Zone (HVHZ), what is the maximum allowed deflection for a
single glass lite under design load?
A. L/175
B. L/60
,C. L/240
D. L/360
Answer: A
Conceptual Explanation: For glass supported on four sides, the Florida Building Code
limits deflection to L/175 of the span to prevent pull-out or breakage under wind loads.
3. When installing setting blocks for a 60-inch wide lite of glass, where should they be ideally
placed?
A. At the 1/4 points of the width
B. At the 1/2 points of the width
C. At the 1/8 points of the width
D. 6 inches from each corner
Answer: A
Conceptual Explanation: Standard practice for glass installation requires setting blocks to
be placed at the 1/4 points (15 inches from each end for a 60-inch lite) to distribute weight
evenly.
4. Which type of safety glazing is required for glass in a sliding door according to CPSC 16 CFR
1201 Category II?
A. Annealed glass with a film
B. Heat-strengthened glass
, C. Laminated glass
D. Wired glass
Answer: C
Conceptual Explanation: Laminated glass (or fully tempered glass) meeting Category II
impact standards is required for hazardous locations like sliding doors to prevent injury
upon impact.
5. What is the minimum shore A durometer hardness for neoprene setting blocks?
A. 40 to 50
B. 60 to 70
C. 100 to 110
D. 80 to 90
Answer: D
Conceptual Explanation: Setting blocks must be hard enough to support the glass weight
without excessive compression; 80 to 90 Shore A durometer is the industry standard.
6. When performing a ‘Large Missile Impact Test’ for Florida HVHZ compliance, what is the
weight and speed of the missile?
A. 2 lb. 2x4 at 50 fps
B. 9 lb. 2x4 at 34 fps
C. 9 lb. 2x4 at 50 fps
