NCIDQ - Building Regulations and Codes (Chapter 7)
QUESTIONS WITH CORRECT SOLUTIONS.
Model Code correct answers Building code that has been written by a group comprised of
experts knowledgable in the field, without reference to any geographical area
International Building Code (IBC) correct answers Primary model code; it combines provisions
of three previous model codes
Building Codes correct answers Written to protect the health, safety, and welfare of the public
Model Codes correct answers Written based on the idea of the "least acceptable risk"; set a
minimum level of protection for building and occupant safety
National Electrical Code (NEC) correct answers Electrical code used by all jurisdictions;
published by NFPA
Standards-Writing Organizations correct answers ASTM International, NFPA, American Society
of Hearing, ASHRAE, IES, GA, TCNA
ANSI correct answers Organization that does not write or develop standards but approves
standards developed by other organizations and works to avoid duplications between different
standards
Underwriters Laboratories (UL) correct answers One of the most well known testing
laboratories; develops standards and tests products for safety
Listed Label correct answers When a complete and total product is successfully tested by UL
Classified Label correct answers Samples of the product were tested for certain types of uses
only by UL
ASTM E119 correct answers Standard Test Methods for Fire Tests of Building Construction and
Materials; Test that involves building a sample of the wall or floor/ceiling assembly in the
laboratory and setting a standard fire on one side. First part is to determine the temperature at
which the surface or adjacent materials on the side of the assembly not exposed to the heat
source will combust. Second part is the host stream test which uses a high-pressure host stream
to simulate how well the assembly stands up to an impact from falling debris and the cooling and
eroding effects of water
ASTM E119 correct answers For construction assemblies, a time-based rating is given to the
assembly in accordance with this test
