FLAMMABILITY CODES REFERENCE GUIDE

Please use the reference guide & specifications to determine which fire code applies to the textile you have selected. Flammability testing determines a fabric's resistance to burning. There are a variety of fire codes employing different methods and standards depending on the intended end use of the fabric, (i.e. Seating, Drapery, Panel, Wallcovering.)

SEATING CODES:

  • California Technical Bulletin 117 - Section E:

  • (The standard industry code for seating-All Momentum Group fabrics pass)
    • Test Method:2" x 6" sample is exposed at a 45 degree angle to a 5/8" pencil thin flame for 1 second.
    • Standard to Pass: Sample must not burn more than 5" in 3.5 seconds.
  • California Technical Bulletin 133:
    • Test Method: A square gas burner is placed on the test furniture. It is ignited and burns for 80 seconds.
    • Standard to Pass: Measurements of temperature, mass loss of the furniture, concentrations of carbon dioxide, unburned hydrocarbons and opacity of smoke are made. Heat release measurements based upon oxygen consumption are also made.
    • Note: California 133 is a full burn test (a composite test) meaning the test is done on a complete piece of furniture, not on the individual components. No Fabrics Can Be Pre-Approved. The use of a fire barrier is helpful in aiding to pass this test.
  • Boston Fire Code (BFG 11-2):
    • Test Method: A vertical sample 1 1/2" x 10" hangs 1 1/2" into a 6" flame for 10 seconds.
    • Standard to Pass: Drip burn is prohibited during first 2 seconds of exposure.
  • Massachusetts Fire Code (FPR - 20):
    • Test Method: A vertical sample 1 1/2" x 10" is exposed to 2" of a 6" flame for 10 seconds.
    • Standard to Pass: After flame maximum of 2 seconds. Afterglow maximum of 40 seconds.
  • UFAC:
    • Test Method: A sample is placed over a standard foam substrate and exposed to a burning cigarette.
    • Standard to Pass: Class I - Char length less than 1 3/4"
      Class II - Char length over 1 3/4"
  • BIFMA x 5.7 - Class I:
    • Test Method: 5 samples 6 1/2" x 3" are exposed to a 5/8" flame for 1 second.
    • Standard to Pass: Flame spread is 1 second longer.
  • City of New York - (Bulletin #44):
    • Test Method: A vertical 2 1/2" x 12" sample hangs 3/4" into a test flame for 12 seconds.
    • Standard to Pass: Afterflame maximum average is 3 seconds. Afterglow maximum is 20 seconds.
  • NFPA 260:
    • Test Method: A sample is placed over a standard foam substrate and exposed to a burning cigarette.
    • Standard to Pass: Class I - Char length less than 1 3/4"
      Class II - Char length over 1 3/4"

VERTICAL CODES:

  • NFPA 701 - Small Scale:
    • Test Method: 10 samples 3 1/2" x 10are conditioned in an oven at temperatures of 140-145 degrees for 1 hour then exposed to a 1/2long flame 12 seconds.
    • Standard Pass: Afterflame maximum is 2 Char length cannot exceed 3No drip burn allowed.
  • NFPA 701 - Large Scale:
    • Test Method: 10 samples 5" x 7" are conditioned in an oven at temperatures of 140-145 degrees for 1 hour then exposed to an 11" long flame for 2 minutes.
    • Standard to Pass: Afterflame maximum is 2 seconds. Char length cannot exceed 10". No drip burn in allowed.
  • ASTM E-84:
    • Test Method: A horizontal sample 21" x 24" is exposed to a 4 1/2" test flame for a 10 minute period.
    • Standard to Pass: Using a complicated formula, a flame spread distance-time relationship is calculated.
  • UL:
    • Test Method: 10 square feet of the panel system with the fabric in question are subjected to UL Test 723.
    • Standard to Pass: Flame spread index must be 200 or less. Also the smoke developed index must be 200 or less.
TRANSPORTATION CODES:
  • FAR 25.853B - Aircraft:
    • Test Method: A vertical 2" x 12" sample hangs 3/4" into a 1 1/2" flame for 15 seconds.
    • Standard to Pass: Afterflame maximum average is 15 seconds. Char length maximum average is 8". Drip burn maximum average is 5 seconds.
  • MVSS 302 - Automobiles, Buses, RV's:
    • Test Method: The edge of a 4" x 14" sample is exposed horizontally to a 1 1/2" flame for 15 seconds.
    • Standard to Pass: Maximum burn rate is 4' per minute or "self-extinguishing" before burning 2" past the start of the timing zone.
