Introduction

Static Smoke Barrier glass D600 & DH classes

Flames are not the only danger during a fire. Smoke can also reach extreme temperatures and impede the safe evacuation of building occupants. Smoke containment screens were designed to mitigate this risk. These screens are regulated to provide stable fire resistance at a constant temperature (600 °C) or on a standardized time-temperature curve (ISO 834).

Performance

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)
D₆₀₀ 30	600	30
D₆₀₀ 60	600	60
D₆₀₀ 90	600	90
D₆₀₀ 120	600	120
D₆₀₀A	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).
