The division of building fire resistance rating is one of the basic measures in building fire prevention technology measures. China's building design code divides the fire resistance rating of buildings into one or 2. 3. four levels, with the highest level and the strongest fire resistance capacity; the lowest level and the weakest fire resistance capacity. The fire resistance rating of a building depends on the fire performance and fire resistance limits of the building elements that make up the building. The so-called building component refers to the building wall, foundation, beam, column, floor, stairs, ceiling and a series of basic components.

Class A fireproof material means that the combustion performance of the material is made of non-combustible material. The fire rating A is a fire resistant material that is resistant to fire for 3 hours.

Determination Conditions for Fire Resistance Limit:

◆ There are three conditions for building components to reach fire resistance limit: loss of supporting ability; Integrity; The period of time until the fire isolation effect is lost; As long as any of the three conditions is reached, it is determined that it has reached its fire resistance limit. The division of building fire resistance rating is one of the basic measures in building fire prevention technical measures.
