Smoke barriers tested for a constant temperature stability time (D) must maintain their integrity for a defined time at 600 °C. Barriers are classified in accordance with EN 13501-4 (Classification using data from fire resistance tests on components of smoke control systems).
Normalized classes
| Classes | Temperature (°C) | Time (min) |
|---|---|---|
| D 600 30 | 600 | 30 |
| D 600 60 | 600 | 60 |
| D 600 90 | 600 | 90 |
| D 600 120 | 600 | 120 |
| D 600A _ | 600 | Any duration beyond 120 min |
Smoke containment screens tested according to a stability period with the standardized time-temperature curve (DH) must maintain their integrity for a defined time-temperature pair. Barriers are classified in accordance with EN 13501-4 (Classification using data from fire resistance tests on components of smoke control systems).
Classes for smoke barrier systems operating in high temperatures
| Classes | Temperature (°C) | Time (min) |
