■UL94 standard (Vertical flame retardancy test method and criteria)
| Criteria | Flame retardant classification | ||
|---|---|---|---|
| V-0 | V-1 | V-2 | |
| Respective afterflame time for each specimen (t1 and t2) | ≦10s | ≦30s | ≦30s |
| Total afterflame time for a set of 5 specimens for each conditioning tf | ≦50s | ≦250s | ≦250s |
| Total of afterflame time and residual dust time after second flame contact of each specimen (t2+t3) | ≦30s | ≦60s | ≦60s |
| Afterflame and residual dust reaching the holding clamp | No | No | No |
| Molten drippings or flaming falling objects that ignite cotton absorbent rug | No | No | Yes |
- tf: Total afterflame time (s)
- t1: First afterflame time of specimen (s)
- t2: Second afterflame time of specimen (s)
- t3: Residual dust time (s)
- Afterflame: Flame that connects after the ignition source is removed
- Afterflame time: Length of time that an afterflame lasts under specified test conditions
- Residual dust: Red-hot combustion that persists after the ignition source is removed and flaming combustion is over
