Installing of fire resistant door
The installation of fire doors counts as a measure for the “fire protection closure” (FSA).
Fire protection is intended to prevent the spread of a fire and to limit it in the event of an actual outbreak.
Each fire protection element is accompanied by installation instructions.
Door and wall define the type of assembly. The door leaf is fastened with the frame. The door frame is connected to the wall. Frame and wall can be mounted together in different ways. The material of the wall ultimately decides which installation is most suitable.
The strength between frame and wall depends on the number and placement of the anchor points. The choice of dowels determines the reliability of fire protection. If dowels, screws and frames are not tight enough and come loose in the event of a fire smoke and flames can spread unrestricted.
Customer receives a completed declaration of conformity after the installation of the fire door.
This guarantees that the fire door has been installed professionally and properly.
Fire doors Mandatory marking
The preventive fire resistance of a fire protection door is subject to mandatory labelling. In Germany, the decision as to when and where a door must be installed for fire protection is made by the state building code according to a prescribed standard. Depending on the type, the functional doors must:
- fire-resistant
- Close tightly
- Be self-closing
The fire doors marking requirement includes a number of requirements.
The marking contains the following data in the structure:
- Door with DIN and T (fire resistance) specification (T30, T60, T90, T120 and T180)
- Manufacturer with manufacturer’s identification number and name
- Monitoring sign “Ü”
- the year of manufacture
The regulation applies to all materials of fire and smoke protection doors.
Fire resistance classes
Components of building are classified in fire resistance classes depending on the fire resistance duration. The standardized classification clarifies:
- is the component basically made of combustible building materials;
- how flame-retardant is the building material;
- how many minutes can the component withstand a fire.
The fire resistance classes are proven by fire tests. Depending on the reaction to fire, the component is issued with a test certificate based on DIN 4102.
Fire resistance class table:
F60 ≧ 60 minutes highly fire resistant
F90 ≧ 90 minutes fire-resistant
F120 ≧ 120 minutes highly fire resistant
F180 ≧ 180 minutes highly fire-resistant
Components receive special code letters. The “T” stands for fire protection closures (flaps, gates, doors). In concrete terms, this means that a T90 fire door. In addition to this time component, there are also three factors in the fire safety test:
- Carrying capacity
- Room closure
- Thermal insulation
The fire resistance of a component is considered to be broken if one of the three factors no longer applies in the fire test.
OTHER USEFULL INFO
Each fire door is manufactured and certified under third-party supervision.
Fire protection and smoke protection doors must comply with the standard EN 16034, the “CE” recognized throughout Europe.
The requirements for fire doors and their testing have been significantly tightened by the European standards (e.g. modified temperature sensors and increased pressure conditions in the fire chamber). As a result, the fire door is subjected to much greater stress during fire testing than during testing according to the old DIN 4102-5 standard. The classification of fire doors according to the DIN EN 16034 is explained below (for example EI²30-C5-S):
| E | Room closure | Prevention of flame propagation |
| I | Thermal insulation | Describes the ability of the fire protection element to determine the temperature at the Surface of the door on the side facing away from fire at certain measuring points opposite the Limit initial temperature. |
| 1/2 | Index of thermal insulation | 2 = measuring range of thermal insulation in 100mm from the edge of the door, 1= measuring range of the thermal insulation in 25mm from the door edge. |
| 30/60/90/120 | Fire resistance , duration | Time in minutes in which the fire protection element allows flame passage disabled. |
| S | Smoke protection function | Prevention of smoke passage at up to 50 Pa air pressure. |
| 200 | Smoke protection function | The number “200” describes the test both at room temperature and at 200°C in the Test chamber. |
| C | Self-locking ability | Self-closing is the ability of an open door completely, automatically by stored energy. This is achieved by an overhead door closer. |
| 0/1/2/3/4/5 | Durability of self-closure | it must be ensured that the self-closing function remains permanently functional. Depending on the number of cycles achieved, it is classified in a usage category. The number 5 means type designation of a fire door the achievement of 200,000 Closing cycles. |
An additional label must be affixed to the following information:
Manufacturer, product type and/or designation, serial or reference number of the product, fire resistance and/or Smoke protection classification and / or classification of self-closure.
A declaration of performance must be handed over.
The fire protection element is marked by the manufacturer by a label (on the strip edge of the door leaf) and by proves the submission of a letter of admission. The manufacturer certifies the approval-compliant Execution of the element by self-monitoring and external monitoring.
