The company has successfully completed the EN 1634-3 smoke control tests, adding the Sa4 ambient temperature smoke leakage classification to its existing EI(2)60 fire resistance classification.
This dual performance standard applies to EBD's EBD65-FireEI, EBD44-FireE, and EBD44-EXT.FireE door types, underscoring their excellence in both fire resistance and smoke control.
Comprehensive Protection Standards
These doors meet the rigorous EN 1634-1 (fire resistance) and EN 1634-3 (smoke control) standards, ensuring comprehensive protection.
Suitable for single and double leaf doorsets, these products can also include vision panels, providing flexibility and enhanced safety for various applications.
The advanced testing measures air leakage at different pressures, ensuring minimal smoke passage for optimal safety.
EBD's exceptional results enable the production of doors with clear opening heights up to 2950mm, showcasing their ability to provide flexible solutions for oversized doors.
Understanding Smoke Control Doors: Sa3 vs. Sa4
In June 2023, updates to the fire resistance classification standard (EN 13501-2) brought changes to the smoke leakage classification.
Previously, the EN 1634-3 smoke control test standard was a little controversial as it allowed the gap beneath the door to be sealed with impermeable material, potentially misrepresenting real-world behaviour.
EBD welcomes the recent clarifications, especially concerning smoke leakage at ambient temperature.
The latest version of EN 13501-2 introduces two classifications: Sa3 and Sa4, denoting whether the door has been tested with seals on three sides (vertical sides and head) or four sides (including the threshold).
The EBD65-FireEI has achieved the Sa4 classification, demonstrating superior smoke control performance without the need for sealing the gap beneath the door.
The updated EN 13501-2 classification reports for EBD65-FireEI, EBD44-FireE, and EBD44-EXT.FireE products are based on modern test evidence from the past three years.
This standard is crucial for fire resistance and smoke control classification, ensuring the doors meet the highest safety standards.
- EN 13501-2 Focus: This standard concentrates on fire resistance and smoke control, classifying performance into categories such as E (integrity), I (insulation), and W (radiation).
- Updated 2023 Edition: The latest reports are based on the current standard, utilising modern test evidence.
- Continuous Investment: EBD Steel Doors prioritises up-to-date testing and certification, avoiding reliance on outdated reports and assessments.
