IEC 62236-3-1-2018 PDF

Full title and description

Railway applications — Electromagnetic compatibility — Part 3-1: Rolling stock — Train and complete vehicle. This International Standard specifies emission and immunity provisions applicable to complete railway vehicles (rolling stock) to ensure electromagnetic compatibility between the train and external systems and services.

Abstract

IEC 62236-3-1:2018 (Edition 3.0) sets out the emission limits and related measurement and assessment methods for rolling stock (traction units, hauled stock and trainsets, including urban vehicles operating in city streets). The document updates and clarifies the previous edition, aligns rolling-stock EMC requirements with the general framework given in IEC 62236‑1, and addresses specific radiated and conducted emission criteria as well as considerations for immunity and interaction with outside-party telecommunication lines.

General information

• Status: Published / Current (Edition 3.0).
• Publication date: 15 February 2018.
• Publisher: International Electrotechnical Commission (IEC).
• ICS / categories: 33.100 (Electromagnetic compatibility), 45.060.01 (Railway rolling stock in general).
• Edition / version: 3.0 (2018).
• Number of pages: 40 pages (official bilingual English/French edition); Redline version available (63 pages) showing changes vs. the previous edition.

Scope

Specifies emission limits (radiated and conducted) for rolling stock to the outside world and provides related measurement and assessment principles. It applies to all types of rolling stock (traction vehicles, hauled vehicles and trainsets, including urban vehicles) and is intended to be read together with IEC 62236‑1 (general provisions for railway EMC). The standard clarifies definitions and applicability and highlights special considerations (for example, certain low-frequency radiated H-field values moved to an informative annex due to reproducibility and relevance concerns).

Key topics and requirements

• Emission limits for rolling stock: radiated and conducted emissions specified for compatibility with external services and spectrum users.
• Measurement principles and distances for radiated emission assessments suitable for vehicles.
• Interaction considerations with outside-party telecommunication lines and psophometric current issues.
• Clarified definitions, scope and applicability compared with the previous edition.
• References to companion parts of the IEC 62236 series (general rules and apparatus requirements) for a complete EMC compliance program.
• Redline version available to show technical changes made in this edition.

Typical use and users

Used by rolling-stock manufacturers, vehicle systems integrators, EMC engineers, test laboratories, railway operators, certification bodies and procurement/specification teams. It is applied during vehicle design, EMC planning, pre‑qualification testing, type approval and safety/compliance demonstrations where electromagnetic compatibility with external services and other railway systems is required.

Related standards

FAQ

Q: What is this standard?

A: IEC 62236-3-1:2018 is an International Standard that defines electromagnetic emission and related assessment requirements for complete railway vehicles (rolling stock).

Q: What does it cover?

A: It covers emission limits (radiated and conducted) from rolling stock to the outside world, measurement principles, and compatibility considerations; it is intended to be read with IEC 62236-1 and complements apparatus-level requirements covered in other parts of the 62236 series.

Q: Who typically uses it?

A: Rolling-stock manufacturers, EMC/test engineers, certification and conformity assessment bodies, railway operators, and procurement/specification teams use it to design, test and approve vehicles for EMC compliance.

Q: Is it current or superseded?

A: The document is the 2018 third edition (Edition 3.0). It replaced the 2008 edition; users should check the IEC publication status for any amendments or a newer edition before formal compliance activities.

Q: Is it part of a series?

A: Yes — it is part 3-1 of the IEC 62236 series (Railway applications — Electromagnetic compatibility). The series includes a general part (62236-1) and other parts that address apparatus and subsystem requirements (for example, 62236-3-2).
