Understand every code in your specification on one page: which standard tests what, and what each class means.
Doorsmar is the first and only Turkish wooden door manufacturer accredited by IFCC to UL/ANSI standards. That means certified, locally manufactured delivery on international projects that specify US standards.
The US positive-pressure fire test, replicating real fire conditions. A staple of Middle East and global hotel chain specifications.
The European fire resistance test using the ISO 834 standard fire curve. Turkish fire regulations reference this scope.
The British fire test standard, required on UK and Gulf projects.
The European classification standard that converts test data into E / EI / EW classes.
Smoke control (S class) testing; leakage measured at ambient and/or 200°C.
Quality management system covering all our production processes.
A rating like "EI90" carries two facts: the letters give the performance type, the number gives the duration in minutes.
| Class | Name | What Is Tested? | Typical Use |
|---|---|---|---|
| E | Integrity | Prevention of flame and hot gas passage | Escape corridor doors |
| EI | Integrity + Insulation | Plus surface temperature limits: mean ≤140°C, point ≤180°C | Fire compartment doors |
| EW | Integrity + Radiation | Heat radiation on unexposed face ≤15 kW/m² | Spaces adjoining escape routes |
| S / Sa / S200 | Smoke Control | Smoke leakage rate (EN 1634-3) | Hospital, hotel corridors |
| 30 / 60 / 90 / 120 | Duration (minutes) | Time the criterion is maintained under test | Regulatory requirement per space |
Our tests are carried out at TSE and Efectis laboratories. Cat A / Cat B in reports refers to direct application vs. the +15% extended field of application. For model-level lists see the DMSteel test tables and the DMWOOD Efectis report (EEA-26-161).
Our FDIS-certified engineers inspect, maintain and test fire rated doors in high-traffic buildings, delivering comprehensive reports. A fire door must stay as safe as the day it was installed.
Our engineers support you from site survey to installation. Send us your dimensions and required rating — we respond the same day.
