Hi Barry,
The difference between UL94 (July 29, 1997) classs are listed below.
1. Afterflame time for each individual sample t1 or t2
V-0 <=10s. ; V-1 <= 30s. ; V-2 <= 30s.
2. Total afterflame time time for any condition set (t1 plus t2
for the 5 specimens.
V-0 <=50S. ; V-1 <= 250S. ; v-2 <= 250s.
3. Afterflame or afterglow of any sample up to the holding clamp.
V-0, V-1, and V-2 Not allowed
4. Cotton indicator ignited by flaming particles or drops
V-0 and V-1 Not allowed; V-2 Allowed
Like many independent labs out there, we do this type of testing
quite a bit.

I believe that it is the time that it takes the material to
extinguish once the flame has been removed.
immediately vs 1 sec?

Good morning Tech Net.
I have a question in regards to UL Flame ratings for PCB's. My incoming
inspectors have asked me what the difference is between 94V-0 and 94V-1.
any help is appreciated.
Thank you in advance.
