Q1: What is UL 94?
A1: UL 94 is a plastics flammability standard released by Underwriters Laboratories (UL) of the USA
The standard classifies plastics according to how they burn in various orientations and thicknesses. From lowest (least flame-retardant) to highest (most flame-retardant), the classifications are:
HB: Slow burning on a horizontal specimen; burning rate < 76 mm/min for thickness < 3 mm.
V2: Burning stops within 30 seconds on a vertical specimen; drips of flaming particles are allowed.
V1: Burning stops within 30 seconds on a vertical specimen; no drips allowed.
V0: Burning stops within 10 seconds on a vertical specimen; no drips allowed.
5VB: Burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may develop a hole.
5VA: Burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may not develop a hole.
Tests are generally conducted on a 5″ x 1/2″ specimen of the minimum approved thickness. For 5VA and 5VB ratings, tests are performed on both bar and plaque specimens, and the flame ignition source is approximately five times as severe as that used for testing the other materials.
A2: If the plastic specimens reach V0 standard, they must:
Specimens must not burn with flaming combustion for more than 10 seconds after either test flame application.
Total flaming combustion time must not exceed 50 seconds for each set of 5 specimens.
Specimens must not burn with flaming or glowing combustion up to the specimen holding clamp.
Specimens must not drip flaming particles that ignite the cotton.
No specimen can have glowing combustion remain for longer than 30 seconds after removal of the test flame.
