In what consists the fire resistance?
It is the property of a building element or other components of a building, of keeping the stability and / or sealing, thermal insulation, mechanical strength or any other specific function, for a certain period of time, when subjected to heating process resulting from a fire.
What is the difference between a flameproof door (E) and a fire rated door (EI)?
A flameproof door (E) should ensure the tightness against flames and hot gases. The fire rated door (EI) should resist without significant deformation during the time for which it was rated (mechanical stability), should ensure the tightness against flames and hot gases and should thermally insulate for a certain period of time (thermal insulation).
E = tightness against flames and hot gases | ability of a building element with the function of compartmentation to not let pass any flames or hot gases, for a certain period of time.
I = thermal insulation | ability of a building element with the function of compartmentation, to ensure that the temperature of the unexposed side to fire do not rise above a given degree, from the beginning and for a certain period of time.
Fire stability | ability of a building element with the function of load bearing to resiste to collapse for a specified period of time when subjected to the action of fire.
NOTE 1 | The time for which the door was rated is presented in minutes (30, 45, 60, 90 or 120). For example, a 30 minutes fire rated door is rated as EI30.
NOTE 2 | The fire resistence rate covers all the lower rates, including flameproof rates.
What are the differences between the testing procedures for fire resistance ratings in EI1 and EI2?
I1– The thermocouples on the leaf should be placed 25 mm from the gap (between frame and leaf) and those on the frame should be placed 100mm from the corner connection. During the test, the increasing of temperature in the leaf and the frame (at any point on the side not exposed to fire) must not exceed the initial temperature of over 180 ° C and the average temperature must never exceed 140 ° C.
I2 – The thermocouples on the leaf should be placed 100 mm from the gap (between frame and leaf) and those on the frame should be placed 100 mm from the corner connection. During the test, the increasing of temperature in the leaf and the frame (at any point on the side not exposed to fire) must not exceed the initial temperature of over 180 ° C, the temperature of the frame must not exceed 360 ° C and the average temperature must never be above 140 ° C.
What is a thermocouple?
The thermocouples are electronic devices whose function consists in measuring the temperature. Are fundamentally composed of two filaments of different metals or of alloys of different composition. The filaments are welded at one extremity, designated hot joint or measuring joint, and the other extremity, the circuit is closed.

What is the fire compartmentation?
Part of a building comprising one or more spaces, rooms or floors, enclosed by elements of construction with the appropriate fire resistance to ensure the protection of the building, prevent the fire spreading to the rest of the building or split the fire load, during a certain period of time.
It is required to apply a closing recovery system in a fire rated door?
Yes. A fire rated door must have a closing recovering system: ability of a building element that furnish a doorway to, in case of fire, take a position that guarantees the door closes without human intervention. To respond to this function, is incorporated a hidraulic doorcloser (per leaf) that may be apparent (with articulated arm or sliding rail) or hidden (embedded on top of the leaf).
What is an anti-panic bar?
An anti-panic bar is a mechanical device installed in a door to allow its easy open in case of emergency evacuation, by pressing with the user's body, without using the hands.
NOTE: All combinations of accessories and harware are possible both in doors with anti-panic bar and with a pair of handles.
What is the free passage?
The free passage (W x H) corresponds to the width / height measured between the inner boundary of the frame, equavalent to the largest dimensions so that persons or objects can pass through the door.
What is a unit of passage?
It is a theoretical unit used in to evaluate the necessary width to the passage of people during evacuation. The correspondence in metric units, rounded down to the nearest whole number, is as follows:
• 1 UP = 900mm
• 2 UP = 1400mm
• n UP = n x 600mm
How it is defined the direction of opening to a door?
Positioned on the opposite side to the hinges we can see the inside face of the door. When we press the handle or the anti-panic bar, we put into action its rotational movement that can process up to the right or to the left. Thus we define its direction of opening (right door or left door).
What is an emergency exit?
An emergency exit is an exit to a protected escape route or a safety zone, which is not normally available for public use.
