WebUL 94 5V Rating: 5V, 5VA, 5VB ‐ Vertical Testing is done on both bar and plaque specimens. For any material to achieve 5V classification, the test specimens must not burn with flaming and/or glowing combustion for more than 60 seconds after the fifth flame. Also, the test specimens must not drip. Mixtures of dispersed combustible materials (such as gaseous or vaporised fuels, and some dusts) and oxygen in the air will burn only if the fuel concentration lies within well-defined lower and upper bounds determined experimentally, referred to as flammability limits or explosive limits.
