What is tested
A complete door or shutter assembly — leaf, frame, hardware, glazing and seals — is installed in a supporting construction on a vertical furnace and exposed to the standard fire curve of EN 1363-1 (T = 345 log₁₀(8t + 1) + 20). The furnace pressure is controlled so that the neutral plane sits 500 mm above floor level, putting the upper part of the door under positive pressure.
Performance criteria
- Integrity (E): no sustained flaming on the unexposed face for more than 10 seconds, no ignition of a cotton pad, and gap gauges (6 mm and 25 mm) cannot pass through openings.
- Insulation (I1 / I2): average temperature rise on the unexposed face no more than 140 K and maximum no more than 180 K, with different rules for measuring near the edges for I1 and I2.
The result is reported as, for example, EI2 60 or E 120 under EN 13501-2.
Typical products
Hinged and pivoted steel and timber doors, sliding and rolling shutters, glazed doors, and openable windows — including doors for data centre modules and battery energy storage enclosures sold into Europe, the Middle East and other markets that use European standards.
Frequently asked questions
What is the difference between EI1 and EI2?
Both limit the temperature rise on the unexposed face, but they measure it differently near the edges of the leaf. EI1 is the stricter classification; EI2 allows higher temperatures close to the frame. Many specifications accept EI2.
Can one test cover several door sizes?
The field of direct application in EN 1634-1 allows limited changes to size and some details. Larger variations need an extended application report (EXAP). Plan the specimen with this in mind.
Do you measure radiation (EW)?
Radiation measurement is not within our accreditation scope. Integrity (E) and insulation (I1, I2) are.
