YÜKSELİŞ ELEVATOR PROVIDES EXTRA CONFIDENCE IN FIRE RESISTANT DOORS…

Nikoletta CHERNOVA - YÜKSELİŞ ELEVATOR

When was the last time you have questioned the time for fire resistance of the elevator you use? In fact, before reading this question, have you ever thought of whether the elevator landing doors are fire resistant, and how important it is for your durability and your safety?

The elevator cabins we are get used to nowadays had entered our lives for the first time in the 19th century. The first building to where was installed a passenger elevator had five floors,  was  24-foot-height EV Haughwout at the corner of Broome Street and Broadway, built according to a project drawn by John P. Gaynor in 1857. The elevator was designed for wealthy customers of the fashion store located inside the building. It was powered by a steam engine installed in the basement and was used for advertising purposes. Movement speed - 0.2 m/s. Since that day, elevators have developed in all aspects and have taken a new form. Elevators offer us a brand new experience with their usability, safety and design.
 
Well, can these machines, which we are used to using every day, save our lives one day? Unfortunately, it is not possible to know when the fire will break out, but this is a life-threatening disaster. Therefore, it is useful to take precautions as much as possible. One of them is the fire resistant landing doors of the elevator used in the buildings. These doors, which have various resistance properties, are manufacturing as fire resistant elevator doors in our country according to TS EN 81-58 standard.

They are produced taking into account the norm and the "Regulation on the Protection of Buildings from Fire".

Doors must pass a strickt test before being put into production, and mass production can be started only after a succesfull test. Fire resistance level is not only measured by how many minutes the elevator landing doors can withstand fire,but also are taken into account measurements of the degree of impermeability, insulation and radiation.
The sample used in the examination must have exactly the same properties as the landing doors that will be used in real life. After the test piece is placed in the oven so that the chamber is hermetically sealed, the fume hood is turned on and the oven is ignited. The haet in the oven is controlled by a standard heating curve as EN 1363-1 standard requires.

During the examination, the data obtained from the measuring system are recorded for analysis. When the non-flammable surface temperatures and radiation from this surface and door deformation are measured, these data are also recorded.

Observations regarding the general behavior of the door sample are made during the test and any shape changes are noted.

After the test is over, a detailed test report is prepared containing all the technical specifications of the tested sample and the data recorded during the test. In this report, the performance evaluation regarding the fire resistance is made regarding the result of the test.The sample performance is rated by the leakage rate of the door during the test, the time it takes for a flame  to go out, the temperature rise. Apart from that door panel, the shape change and radiation of the door is measured, the temperature curve of the non-flammable surface are checked. Classification of the door and the application area of this classification are observed and reported in the report as well.

Fire resistant doors prevent the exit of smoke and flame, keeping  it from spreading to stairs and other areas.

Standard fire resistant landing doors produced by Yükseliş Elevator are produced in accordance with EN 81-58 standard and withstand fire for 120 minutes. These doors, which are our own production, have been designed and produced to not only ensure the safety of you and your family, but also to resist fire for a long time.

Doors that are resistant to fire are no longer a luxury, they are a necessity, and as Yükseliş Elevator company, we do all the necessary work to meet this need and offer solid and reliable elevator landing doors to our country and the world.
