When selecting curtains, it is essential to ensure the entire assembly—not just the fabric—is certified to the relevant standard.
- UL 10D (Fire Protective Curtains): This is the primary standard for fire-protective curtains, certifying their ability to withstand intense heat (up to 1,850°F) for durations typically ranging from 1 to 4 hours.
- UL 1784 (Air Leakage/Smoke Control): Curtains with an “S” label meet this standard, meaning they have been tested to limit smoke and draft migration at both ambient and elevated temperatures.
- UL 10B (Hose Stream Test): This standard tests a curtain’s resilience against the thermal shock and physical force of a high-pressure fire hose stream (30 to 120 psi). It is often required for curtains used as replacements for traditional steel fire doors in fire-rated walls.
- UL 864 (Control Units): Governs the control panels and accessories that manage the curtain’s deployment to ensure they function reliably during an emergency
