Technical Knowledge Base

Q

What is the main difference between UL 10C and EN 1634 steel fire door standards?


A

UL 10C and EN 1634 differ primarily in testing methodology and regional acceptance: UL 10C is the positive pressure fire test standard widely used in North America and GCC countries, while EN 1634 is the European standard evaluating fire resistance and smoke control for Europe and Asia.
Testing Method: UL 10C requires mandatory hose stream impact testing; EN 1634 tests both fire integrity (E) and thermal insulation (EI) parameters.
Fire Ratings: UL ratings range from 20 to 180 minutes (3 hours); EN ratings are classified as 30, 60, 90, or 120 minutes.
Regional Usage: Choose UL 10C for Saudi/GCC projects following NFPA guidelines; select EN 1634 for European and British-standard-aligned project specifications.

Q

How long can commercial steel fire doors withstand direct high temperatures?


A

Commercial steel fire doors are engineered to withstand direct high-temperature fire exposure from 20 minutes up to 180 minutes (3 hours), depending on the internal core material, gauge of galvanized steel, and certified testing standard.Fire RatingCore TypeTypical Commercial Applications60 Minutes (1 Hour)Honeycomb / Mineral WoolOffice corridors, residential stairwells, hotel rooms90 Minutes (1.5 Hours)Mineral Wool / PerliteHospital corridors, cleanrooms, commercial utility rooms120–180 Minutes (2–3 Hours)High-Density Mineral WoolIndustrial warehouses, transformer rooms, high-risk fire zones
