3.2.5* Standard. - CORRECT ANSWER-An NFPA Standard, the main text of which
contains only mandatory provisions using the word "shall" to indicate
requirements and that is in a form generally suitable for mandatory reference by
another standard or code or for adoption into law. Non-mandatory provisions are
not to be
considered a part of the requirements of a standard and shall be located in an
appendix, annex, footnote, informational note, or other means as permitted in
the NFPA Manual of Style.
When used in a generic sense, such as in the phrase "standards development
process" or "standards development activities," the term "standards" includes all
NFPA Standards, including
Codes, Standards, Recommended Practices, and Guides.
3.3.1* Absolute Temperature. - CORRECT ANSWER-A temperature measured in
Kelvins (K) or Rankines (R).
,3.3.2 Accelerant. - CORRECT ANSWER-A fuel or oxidizer, often an ignitible
liquid,
intentionally used to initiate a fire or increase the rate of growth or spread of fire.
3.3.3 Accident - CORRECT ANSWER-An unplanned event that interrupts an
activity and sometimes causes injury or damage or a chance occurrence arising
from unknown causes; an unexpected happening due to carelessness, ignorance,
and the like.
3.3.4 Active Fire Protection System. - CORRECT ANSWER-A system that uses
moving mechanical or electrical parts to achieve a fire protection goal.
3.3.5 Ambient. - CORRECT ANSWER-Someone's or something's surroundings,
especially
as they pertain to the local environment; for example, ambient air and ambient
temperature.
3.2.1* Approved. - CORRECT ANSWER-Acceptable to the authority having

conductor can carry continuously under the conditions of use without exceeding
its temperature rating. [70, Article 100]
3.3.7 Ampere. - CORRECT ANSWER-The unit of electric current that is
equivalent
to a flow of one coulomb per second; one coulomb is defined as 6.24 × 1018
electrons.
3.3.8 Arc. - CORRECT ANSWER-A high-temperature luminous electric discharge
across a gap or through a medium such as charred insulation.
3.3.9 Arc Mapping. - CORRECT ANSWER-The systematic evaluation of the
electrical
