Scope: This section gives the requirements for protection against stray currents in DC traction systems. After several decades of practice, there is no obvious corrosion effect on the ground current of AC traction system, and the investigation and research on it is not perfect, so this part only involves the problem of stray current in DC traction system. This section applies to all new DC electrified railways, and its principles can also be applied to existing railways that need to consider the effects of stray currents. Its scope of application includes: - railways; - guided transport systems, such as: trams, elevated railways and subways, mountain railways, trolleybus systems and maglev systems; - material transport systems. This section does not apply to: - traction systems in underground mines; - cranes, rail transport platforms and similar transport equipment, temporary buildings (for example: exhibition structures), because there is no precedent for such facilities to be powered by catenary, they will not Affected by traction systems; — suspended cable cars; — funicular railways; — maintenance works.
