GB/T 45489-2025 is the English-translated version of 中低速磁浮交通轨排通用技术条件.

GB/T 45489-2025 is the Chinese national standard covering the track assembly a medium and low speed maglev vehicle levitates against at up to 120 km/h — the environmental and line conditions, the steel and aluminium profiles and their chemical composition and mechanical properties, the saturation magnetic flux density that decides how much lift the magnets can develop, the conductivity, surface hardness, oxide film and paint film, the dimensions and the track layout, and the static load test. It also fixes a warranty period, which a civil work of this kind rarely carries. First edition, under the Ministry of Housing and Urban-Rural Development. In force from 1 October 2025. Issued on 28 March 2025, it has been in force since 1 October 2025.
