Sec. 1500.44  Method for determining extremely flammable and flammable solids.

    (a) Preparation of samples--(1) Granules, powders, and pastes. Pack 
the sample into a flat, rectangular metal boat with inner dimensions 6 
inches long x 1 inch wide x one-fourth inch deep.
    (2) Rigid and pliable solids. Measure the dimensions of the sample 
and support it by means of metal ringstands, clamps, rings, or other 
suitable devices as needed, so that the major axis is oriented 
horizontally and the maximum surface is freely exposed to the 
atmosphere.
    (b) Procedure. Place the prepared sample in a draft-free area that 
can be ventilated and cleared after each test. The temperature of the 
sample at the time of testing shall be between 68  deg.F.

and 86  deg.F. Hold a burning paraffin candle whose diameter is at least 
1 inch, so that the flame is in contact with the surface of the sample 
at the end of the major axis for 5 seconds or until the sample ignites, 
whichever is less. Remove the candle. By means of a stopwatch, determine 
the time of combustion with self-sustained flame. Do not exceed 60 
seconds. Extinguish flame with a CO2 or similar 
nondestructive type extinguisher. Measure the dimensions of the burnt 
area and calculate the rate of burning along the major axis of the 
sample.
