        T/CECS 901-2021 "Technical Specifications for the Application of Tunnel Fire-proof Coatings" stipulates the design, construction, acceptance and maintenance requirements of tunnel fire-proof coatings, which is an important technical basis for fire-proof painting in tunnel engineering. The regulations are applicable to the selection and application of fire-proof coatings in highway, railway and urban tunnels, and cover the performance indicators, coating process, construction conditions and acceptance standards of fire-proof coatings. The regulations clarify the fire protection performance evaluation methods of tunnel structures and the compatibility requirements of fire-proof coatings and substrates, and put forward guiding opinions on construction safety and environmental protection. Through unified technical specifications, the code aims to improve the fire safety and durability of tunnel engineering, and provide scientific basis and technical support for ensuring the safety of tunnel operation and prolonging the service life.
