Codes Flashcards
ASTM
American Society for Testing and Materials: publishes standards and test procedures; it does not actually perform test, but its procedures and standards are used by testing agencies
NFPA
National Fire Protection Agency: Develop standards related to the causes and prevention of destructive fires
Standard writing organization that have interest in a particular material, product, or filed of expertise, such as ASHRAE (American Society of Heating, Refrigeration, and Air-Conditioning Engineers)
Industry Trade Groups
ANSI
American National Standard Institute: does not develop or write standars; it approves standards developed by other organizations and works to avoid duplications between differ standards
NRTL
Nationally Recongnized Testing Laboratory: when a standard describes a test procedure or requires tests in its description of a material or product, a testing laboratory must perform the test. Underwriters Laboratories (UL) is one of the most well known ____.
passed safety test and is manufactured under the UL follow-up services program
Listed Label
Samples of the product were tested for certain types of uses only
classified Label
building construction and material: evaluates an assembly’s ability to prevent the passage of fire, heat, and hot gasses for a given amount of time; these assemblies are given a rating according to time: 1-4 hr ratings, and for doors and other assemblies 20/30/45 min rating
ASTM E119
Door assemblies: evaluates the ability of a door assembly to resist the passage of flame, heat, and gases
NFPA 252
Window and Glass block assembly: prescribes specific fire and hose stream test procedures to establish a degree of fire protection in units of time
NFPA 257
Surface burning characteristics of building materials; test samples in a narrow chamber that has a controlled flame at one hand. The result is a materials flame spread rating (class A (I), B (II), C (III))
ASTM E84 (Steiner Tunnel Test)
sometimes required in addition to the ASTM E84 test for textile interior finishes or instead of it. It determines the contribution of interior textile and ceiling covering to fire growth
NFPA 265 ( Room Corner Test)
Evaluating contribution of wall and ceiling interior finish to room fire growth; it evaluates material other than textiles and addresses displacement during the ASTM E84 test
NFPA 286
a space or room that in an accessory to a main occupancy but that does not exceed 10% of the floor area of the main occupancy. It does not need to be separated from the main occupancy with a fire barrier
Accessorry use Occupancy
a space or room not exceeding 10% of the floor area of the sotry where it is located which is incidental to a main occupancy and has the same qualifications as the nearest main occupancy but must be separate from the main occupancy by a fire barrier
Incidental Use Occupancy
Type I and II construction
noncombustible materials
Type III Construction
the exterior walls are of noncombustible material and the interior walls must rated
Type IV Construction
heavy timber; the exterior walls are of noncombustible material and the interior walls are of solid or laminated wood without concealed spaces
Type V Construction
least fire resistive; both exterior and interior walls must be rated.
portion of the means of egress that leads to the entrance of an exit. It does not provide a protected path of travel distance but the travel dis. Is measured and regulated
Exist Access
Portion of the means of egress that provides a protected (1 or 2 hr) rating and fully enclosed path of egress from all interior spaces between the exit access and exit discharge.
Exit
Portion of the means of egress between the termination of an exit and public way.
exist discharge
a street, alley, or similar parcel of land essentially unobstructed from the ground to the sky that is permanently appropriated to the public use and has a clear width of no less than 10’
public way
corridor clear width if occupant load is >50
44”
exit/egress stairway width that is ADA
48” b/w handrails
dimensions of a ADA clear floor space
30”x48”
ADA Accessible route slope maximum
5% or 1:20
ADA Accessible route cross slope
1:50 max
Maximum ramp slope
1:12
