IEC 62236-1:2018

Overview

IEC 62236-1:2018 - "Railway applications - Electromagnetic compatibility - Part 1: General" is the foundational document for the IEC 62236 series. It defines the structure and scope of the whole series and specifies the performance criteria applicable across railway EMC standards. This third edition (2018) updates EMC management to align with the IEC 61000 series and contains guiding material (Annex A) describing the electromagnetic behaviour of railway systems.

Key facts:

• Edition: 3.0 (2018)
• Frequency range addressed across the series: DC to 400 GHz
• Main purpose: set framework for EMC management, emission limits and immunity performance for railway systems and equipment

Key topics and requirements

• Structure and content of the IEC 62236 series: Part 1 defines how subsequent parts (Parts 2, 3-1, 3-2, 4, 5) relate and interact.
• Performance criteria: Establishes general emission and immunity objectives that the whole series uses to ensure electromagnetic compatibility within railway systems and with the outside world.
• Management of EMC: Introduces an EMC management approach based on the IEC 61000 family of standards - emphasizing planning, verification and interface control between infrastructure and rolling stock.
• Annex A (informative): Describes railway-specific electromagnetic characteristics, coupling mechanisms, principal emission and immunity phenomena, sources of disturbance (fixed and mobile), and traction system components.
• Scope exclusions: Explicitly excludes nuclear electromagnetic pulse (EMP), abnormal operating/fault conditions, and direct lightning-strike induction effects from the series’ remit.
• Practical testing guidance: Guides limit-setting policies and use of test levels-intended to achieve compatibility in typical operating environments while noting that special locations may require additional measures.

Practical applications / Who uses this standard

• Railway OEMs and rolling stock manufacturers - to design equipment compliant with series-level EMC objectives.
• Infrastructure owners and operators - for EMC planning at the infrastructure/rolling stock interface.
• Signalling and telecommunications engineers - to align equipment immunity and emission characteristics with network needs.
• EMC engineers and test labs - to develop test plans consistent with railway EMC performance criteria.
• Project managers, procurement and regulatory authorities - to specify, verify and accept EMC-related requirements in procurement and certification.

Related standards

• IEC 62236 series: Parts 2, 3-1, 3-2, 4 and 5 (covering system emissions, rolling stock, apparatus, signalling, and fixed power installations)
• IEC 61000 series: referenced for EMC management principles and test methodologies

IEC 62236-1:2018 is essential for anyone implementing an EMC management plan, defining interface limits, or assuring electromagnetic compatibility across modern railway systems.
