  • How to determine the fire resistance level of a building?
  • The fire resistance grades of civil buildings should be divided into first, second, third, and fourth grades

    Fire-resistance grades is a grading scale to measure the fire resistance of a building. It is determined by the flammability and fire-resistance rating of the components that make up the building. Specifying the fire-resistance grade of buildings is one of the most basic measures in the fire protection technical measures stipulated in the building design fire protection code. Factors affecting the selection of fire resistance grades are the importance of the building, the nature of use and fire risk, the height and area of the building, the size of the fire load, and other factors.

    The first, second, third, and fourth grades of building fire resistance are divided as follows:
    1. A first-class fire-resistant building is a mixed structure composed of a reinforced concrete structure or a brick wall and a reinforced concrete structure;
    2. The second-level fire-resistant building is a mixed structure composed of steel structure roof trusses, reinforced concrete columns or brick walls;
    3. The third-level fire-resistant building is a brick-wood structure composed of a wooden roof and a brick wall;
    4. Grade 4 fire resistance is a combustible structure composed of wooden roofs and refractory walls.
    In order to ensure the safety of the building, the building fire resistance rating must be set by taking necessary fire protection measures to make it have certain fire resistance, even if a fire occurs, it will not cause too much loss.


    We can also use the Building Materials Flammability Tester Non-Combustibility Tester to test the Incombustibility of building materials. 

    Building materials non-flammable test furnace is designed and produced according to GB / T5464-2010 / ISO1182: 2002 standard. It is used to test the non-flammability 

    of the main components of homogeneous building products under specific conditions. Its maximum temperature is 900 ℃.

    Warm tips: The general building fire starts to spread about 10 to 15 minutes after the fire starts, and it can be manually called by telephone and other fire hydrants can be used to put out the fire. In large public buildings, high-rise buildings, underground buildings, workshops, and warehouses with high fire risk, automatic alarm devices, and automatic fire extinguishing devices should also be installed.
