Full title and description

St IEC 62236-3-2-2018 — Railway applications — Electromagnetic compatibility — Part 3-2: Rolling stock — Apparatus. This international standard specifies emission and immunity requirements, limits and test methods for electrical and electronic apparatus intended to be installed on railway rolling stock (integration of apparatus on board).

Abstract

IEC 62236-3-2:2018 addresses electromagnetic compatibility (EMC) for apparatus mounted on railway rolling stock. It defines conducted and radiated emission limits, immunity test levels and associated test methods for apparatus ports and power supplies to ensure reliable on-board operation and to limit interference to other railway equipment and to the external environment. The 2018 edition (Ed. 3.0) clarifies several requirements from the previous edition and extends emission and immunity requirements.

Scope

The standard applies to emission and immunity aspects of EMC for electrical and electronic apparatus intended for use on railway rolling stock and to the integration of such apparatus on board. Its objective is to define limits and measurement/test methods for conducted and radiated disturbances and the immunity performance criteria that apparatus must meet to operate reliably in the railway electromagnetic environment. The 2018 edition introduces clarifications and extends emission and immunity requirements compared with the previous edition.

Key topics and requirements

• Definition of applicable ports and categories of apparatus intended for on-board installation (enclosure, I/O, power and earth ports).
• Conducted emission limits on supply and signal lines and measurement procedures.
• Radiated emission limits and radiated measurement techniques relevant to rolling stock.
• Immunity test requirements and levels, including ESD, radiated RF immunity, conducted RF immunity, EFT/burst, surge, power frequency magnetic fields, and power dips/interruption performance criteria.
• Test arrangements, test levels, performance criteria and guidance for integration of apparatus into rolling stock.
• References to measurement standards and alignment with IEC/TC 9 railway EMC series and relevant IEC/ISO measuring methods.

Typical use and users

Manufacturers of on-board railway electrical/electronic equipment, EMC test laboratories, vehicle integrators and design teams, railway system engineers, certification and conformity assessment bodies, and procurement/specification authors use this standard to set EMC requirements, plan and perform EMC testing, and verify equipment compatibility with rolling stock environments.

Related standards

IEC 62236 is a multi-part series. Closely related parts include: Part 1 — General (structure and series performance criteria), Part 2 — Emission of the whole railway system to the outside world, Part 3‑1 — Rolling stock (train and complete vehicle), Part 4 — Signalling and telecommunications apparatus, and Part 5 — Fixed power supply installations and apparatus. These parts together define the EMC framework for vehicles, trackside installations and system-level emission limits.

FAQ

Q: What is this standard?

A: IEC 62236-3-2:2018 is the international EMC standard that specifies emission limits and immunity test requirements for electrical and electronic apparatus intended for installation on railway rolling stock (on-board apparatus).

Q: What does it cover?

A: It covers conducted and radiated emissions, immunity test types and levels (e.g., ESD, radiated RF, conducted RF, EFT/burst, surge, power dips), measurement/test arrangements and performance criteria for apparatus ports and power interfaces when integrated into rolling stock.

Q: Who typically uses it?

A: Equipment manufacturers, vehicle integrators, EMC test labs, railway engineers, certification bodies and specification writers — anyone responsible for designing, testing, integrating or verifying on-board railway apparatus EMC performance.

Q: Is it current or superseded?

A: The edition in force is Edition 3.0, published 15 February 2018. IEC records show a stability date for the 2018 series (parts) through 2030; as of 25 February 2026 the 2018 edition remains the current published edition. Users should check official IEC notices for any amendments or later revisions after that date.

Q: Is it part of a series?

A: Yes — IEC 62236 is a series of parts addressing EMC for railway applications (Part 1 general, Part 2 system emissions, Part 3 sub-parts for rolling stock, Part 4 signalling and telecoms, Part 5 fixed power supply installations, etc.). Designers and assessors generally apply multiple parts of the series together depending on whether the subject is on-board equipment, trackside equipment or whole-system emissions.

Q: What are the key keywords?

A: EMC, railway, rolling stock, apparatus, emissions, immunity, radiated, conducted, test methods, ESD, surge, EFT.
