Full title and description

Railway applications - Electromagnetic compatibility - Part 2: Emission of the whole railway system to the outside world. This international standard defines the electromagnetic environment produced by the whole railway system (including urban mass transit and light rail), describes measurement methods to verify emissions and gives typical field-strength cartography values; it specifies emission limits for the whole railway system toward the external environment.

Abstract

IEC 62236-2:2018 (Edition 3.0) sets radio‑frequency emission limits and measurement procedures for railway systems as a whole, providing guidance and cartography of field levels most frequently encountered around traction and radio-frequency sources. It is intended to help operators, manufacturers and test laboratories assess and control electromagnetic emissions from railway systems to the outside world.

Scope

Specifies the electromagnetic environment of the whole railway system and the emission limits the system must respect with respect to the outside world. The document covers measurement methods to verify emissions and provides typical field-strength cartography values encountered around traction equipment, on-board systems and other railway installations; it applies to mainline railway, urban mass transit and light rail systems.

Key topics and requirements

• Definition of the electromagnetic environment produced by the complete railway system (including urban and light rail systems).
• Specification of measurement methods and test arrangements to assess radiated emissions from the railway system.
• Field-strength cartography: typical values and mapping of the most frequently encountered electromagnetic fields around railway installations.
• Numerical emission limits (RF) for the whole railway system toward the external environment.
• Normative references to CISPR and IEC measurement standards (eg. CISPR 16 series) that define measuring apparatus and antenna/test‑site requirements.

Typical use and users

Used by railway system designers, infrastructure owners and operators, rolling‑stock and equipment manufacturers, EMC engineers, test laboratories and conformity/approval bodies to: plan and assess EMC performance of railway installations, verify compliance with emission limits, perform on‑site or laboratory measurements, and to inform procurement and regulatory requirements.
