TB/T 3623.2-2026 specifies fire performance requirements for materials and components used in locomotives and railway vehicles, replacing multiple previous standards and aligning with international benchmarks.
The adoption of TB/T 3623.2-2026 enhances fire safety standards for Chinese railway vehicles, promotes high-quality development of rail transport equipment, and provides a technical foundation for international standardization of railway fire safety. It ensures that materials and components meet rigorous fire performance criteria, improving overall passenger safety and operational reliability.
