Flammability
A number of test procedures have been developed which can be used for the evaluation and comparison of
various materials to support combustion.
UL 94 Vertical Burning Test
Samples of a material, with dimensions 127mm by 12.7mm and the thickness of the intended end use product,
are tested in an unaged “as manufactured” state and in an aged state (seven days at 158°F, 70°C). The test
requires the placement of a precisely controlled flame under a vertically supported specimen for a ten second
period. The controlled flame is removed and the duration of flaming combustion of the specimen is recorded.
When the flaming combustion of the specimen extinguishes, it is immediately subjected to an additional
controlled flame exposure. After the additional ten seconds of exposure, the controlled flame is removed,
and the duration of flaming combustion of the specimen is recorded. A piece of surgical cotton is placed under
the specimen. If drips ignite the cotton, this fact is also recorded.
Materials Classed 94V-0
Requirements:
• None of the specimens will burn with flaming combustion for more than ten seconds after either
application of the controlled flame
• The total flaming combustion time will not exceed 50 seconds for the ten controlled flame applications
(two controlled flame applications for each of the five specimens)
• None of the specimens will burn with flaming or glowing combustion up to the holding clamp
• None of the specimens will drip flaming particles that ignite the dry absorbent surgical cotton
located 12 inches (305mm) below the test specimen
• None of the specimens will exhibit glowing combustion that persists for more than 30 seconds after
the second removal of the controlled flame
Materials Classed 94V-1
Requirements:
• None of the specimens will burn with flaming combustion for more than 30 seconds after either
application of the controlled flame
• The total flaming combustion time will not exceed 250 seconds for the ten controlled flame applications
(two controlled flame applications for each of the five specimens)
• None of the specimens will burn with flaming or glowing combustion up to the holding clamp
• Specimens may drip flaming particles which burn only briefly, and may not ignite the dry absorbent
surgical cotton located 12 inches (305mm) below the test specimen
• None of the specimens will exhibit glowing combustion that persists for more than 60 seconds after the
second removal of the controlled flame
Materials Classed 94V-2
Requirements:
• None of the specimens will burn with flaming combustion for more than 30 seconds after either
application of the controlled flame
• The total flaming combustion time will not exceed 250 seconds for the ten controlled flame applications
(two controlled flame applications for each of the five specimens)
• None of the specimens will burn with flaming or glowing combustion up to the holding clamp
• Specimens may drip flaming particles which burn only briefly, and may ignite the dry absorbent surgical
cotton placed 12 inches (305mm) below the test specimen
• None of the specimens will exhibit glowing combustion that persists for more than 60 seconds after
the second removal of the controlled flame
