Testing Standards Flashcards
ASTM E119
(standard test methods for fire tests of building construction and materials)
Evaluates a wall or floor/ceiling assembly to prevent the passage of fire,heat, and hot gases for a given amount of time.
Gives fire ratings of walls, structure, and floor construction assemblies
(How long can it go before falling)
NFPA 252
(Standard methods of fire tests of door assemblies)
Evaluates the ability of a door to resist the passage of flame, heat, and gases
Establishes a time-endurance rating
NEPA 257
(Standard on fire tests for window and glass block assemblies)
Prescribes specific fire and hose stream test procedures to establish a degree of fire protection - in units if time - for window opening in fire rated walls
What does flammability tests determine for finish materials ?
- flammability of material (does it burn w applied heat or supports combustion)
-degree of flammability (how fast it spreads)
-amount of smoke and toxic gas it produces when ignited
ASTM E84
(Standard test method for surface burning characteristics of building materials)
Steiner tunnel test
-rates surface burning of interior wall finishes and other building materials
-most common fire testing standard
-generates a smoke developed index (how much can I see?)
3 classes
-class a : 0-25 flame spread - most fire resistant
-class b: 26-75 flame spread
-class c : 76-200 flame spread
NFPA 253 (ASTM E648)
measures the flame spread of flooring systems in corridors and exits
radiant heat is applied at a 30 degree angle over horizontal flooring to simulate thermal radiation levels from an adjacent fire
why is it important? we don’t want the means of egress to burst into flames - duh
class I : required in hospitals, nursing homes, jails, etc.
class II : other commercial occupancies - no residential
ASTM D2859
(Methenamine pill test)
Flammability testing for carpets and rugs
-does it burn ?
Required for all carpet sold in the US
A pill is placed in the center of a carpet sample held in a cube by a metal plate. If the material burns within 1 inch of said metal plate, then it fails the test
NFPA 286
(room corner test)
Evaluates the extent to which wall and ceiling finishes contribute to fire growth (except textiles)
NFPA 265
(Room corner test for textiles)
Contribution of textile wall finish to fire growth in a full-scale mock up
ASTM C1396
Standard spec for gyp board
ASTM E662/NFPA 258
Measures the amount of smoke given off by a flaming or smoldering material/finish
Given a smoke density of 0-800
450 or less for finish materials
Fire partition
Wall assembly with a 1 hour rating
Used in;
-separating dwelling units
-seperating guest rooms in R-1 and R-2 and I-1 occupancies (hotel rooms,etc.)
-seperating tenant spaces
-corridor walls
-elevator lobby separation
Fire partition
Wall assembly with a 1 hour rating
Used in;
-separating dwelling units
-seperating guest rooms in R-1 and R-2 and I-1 occupancies (hotel rooms,etc.)
-seperating tenant spaces
-corridor walls
-elevator lobby separation
Fire barrier
Vertical or horizontal assembly that is fire resistant and designed to restrict the spread of fire, confine fire to limited areas, and/or afford safe passage for egress
Must be continuous from floor to slab
-exit enclosures
-separate different occupancies into different fire areas
BIFMA Level Section 7
furniture sustainability standard about health & wellness impacts
