以下是UL94中的定义,afterflame应该是余焰,不知道余焰和余燃有啥区别? afterglow是余灼.
3.1 Afterflame – Persistence of flaming of a material, after the ignition source has been removed.
3.2 Afterflame Time – The length of time for which a material continues to flame, under specified conditions,
after the ignition source has been removed.
3.3 Afterglow – Persistence of glowing of a material, after cessation of flaming or, if no flaming occurs, after
removal of the ignition source.
3.4 Afterglow Time – The length of time for which a material continues to glow under specified test conditions,
after the ignition source has been removed and/or cessation of flaming.
