Revision Notes
This specification is revised by the Fire Department of our Ministry together with 10 units including the Design and Research Institute of the Ministry of Machinery Industry and the Textile Design Institute of the Ministry of Textile Industry in accordance with the notification of the former State Construction Commission (81) No. 546.
During the revision process, in accordance with the relevant principles and policies of national capital construction and the fire protection work principle of "prevention first, prevention and fire prevention combined", the current status of fire protection design of more than 200 factories, warehouses and civil buildings of various types in 27 large and medium-sized cities was investigated, the experience and lessons of building fire protection design in the past 10 years were summarized, and the advanced building fire protection technology achievements that conform to the actual situation in my country were absorbed from foreign countries. The opinions of relevant units across the country were solicited, and finally the draft was finalized after joint review by relevant departments.
This specification is divided into ten chapters and five appendices. Its main contents include: general provisions, fire resistance level of buildings, factories, warehouses, civil buildings, fire trucks and railway lines into factories, building structures, fire water supply and fixed fire extinguishing equipment, heating, ventilation and air conditioning, electricity, etc.
Since this specification is a comprehensive fire protection technical specification with strong policy and technical nature and wide coverage, it is hoped that all units will combine engineering practice and scientific research, carefully summarize experience, and pay attention to accumulating information during the implementation process. If any modification or supplement is found, please send your opinions and relevant information to the Fire Department of our Ministry for reference in future modifications.

Note: ① The fire resistance level of buildings with wooden columns as load-bearing and non-combustible materials as walls should be determined according to level 4. ② For prefabricated reinforced concrete assembled structures of high-rise industrial buildings, the exposed parts of the joints or metal load-bearing component nodes should be made of fireproof protective layers, and their fire resistance limit should not be lower than the provisions of the corresponding components in this table. ③ For the suspended ceiling of buildings with a second-level fire resistance level, if non-combustible bodies are used, their fire resistance limit is not limited. ④ In buildings with a second-level fire resistance level, if the room partition walls with an area of no more than 100m2 have difficulties in implementing the provisions of this table, non-combustible bodies with a fire resistance limit of not less than 0.3h can be used. ③ When it is difficult to implement the provisions of this table, the partition walls on both sides of the evacuation corridors of civil buildings with the first and second fire resistance grades can be made of 0.75h non-combustible materials.
③ The combustion performance and fire resistance limit of building components can be determined according to Appendix 2. Article 2.0.2 In multi-story and high-rise industrial buildings with a second fire resistance grade, the fire resistance limit of beams and floors in rooms with an average weight of combustibles exceeding 200kg/m2 shall comply with the requirements of the first fire resistance grade, but when automatic fire extinguishing equipment is installed, the fire resistance limit of beams and floors can still comply with the requirements of the second fire resistance grade. Article 2.0.3 For industrial buildings (except Class A and Class B warehouses and high-rise warehouses) with non-combustible components, when the non-load-bearing exterior walls are non-combustible, their fire resistance limit can be reduced to 0.25h, and when they are difficult to burn, they can be reduced to 0.5h. Article 2.0.4 If it is difficult for the floor slabs of buildings with a second-level fire resistance rating (except for the floor slabs of high-rise industrial buildings) to achieve a fire resistance limit of 1h, it can be reduced to 0.5h. The fire resistance limit of the flat roof of a building with a second-level fire resistance rating for people should not be less than 1h.
If it is difficult for the roof of a building with a second-level fire resistance rating to use load-bearing components with a fire resistance limit of not less than 0.5h, metal components without a protective layer can be used. However, fire protection measures should be taken for areas that can be burned by Class A, B, and C liquid flames. Article 2.0.6 The roof surface layer of a building should be made of non-combustible bodies, but for buildings with a first or second level of fire resistance, a combustible roll waterproofing layer can be used on the non-combustible roof base layer.
Interior decoration of the following buildings or parts should adopt non-combustible materials or flame-retardant materials:
1. Guest rooms and public activity rooms of high-end hotels; 2. Studios, recording studios and audio-visual classrooms; 3. Large and medium-sized computer rooms. Engineering Construction Standard Full Text Information System
