Classification of combustion performance
For example, according to the test results in previous years, we still need to remember the combustion performance grades of commonly used building interior decoration materials. In the process of memorizing, we can recite A, then understand B2, and the rest is naturally B 1, which can save you a lot of time.

Interior decoration
The Code for Fire Protection Design of Interior Decoration of Buildings lists the combustion performance grades of decoration materials in single-storey, multi-storey, high-rise and underground civil buildings (Table 5. 1. 1, 5.2. 1, 5.3. 1). According to the exam questions, pay more attention to these forms!

1) For crowded places, places with fire hazards such as fire, fuel oil and gas, and places or parts such as evacuation staircases, evacuation walkways, evacuation rooms and refuge floors in various buildings, thermal insulation materials with combustion performance of Grade A should be adopted.
2) Thermal insulation materials with low smoke, low toxicity and combustion performance not lower than B 1 should be used in other places.
3) The protective layer of thermal insulation system shall be made of incombustible materials. When using thermal insulation material with combustion performance of B 1, the thickness of protective layer should not be less than10 mm. ..
4. For buildings in crowded places, the combustion performance of external thermal insulation materials for external walls should be Grade A. ..
