CISPR 36-2023 PDF

Full title and description

Electric and hybrid electric road vehicles — Radio disturbance characteristics — Limits and methods of measurement for the protection of off‑board receivers below 30 MHz (CISPR 36:2020/AMD1:2023). This entry covers Amendment 1 published in 2023 to the original CISPR 36:2020 document, updating limits, measurement methods and related definitions for protection of off‑board receivers under 30 MHz.

Abstract

This amendment to CISPR 36 specifies additional or revised limits and test methods for radio disturbance (emissions) from electric and hybrid electric road vehicles where those disturbances could affect off‑board radio receivers below 30 MHz. It provides updated definitions (including for REESS and high‑voltage systems), measurement detectors and timing, ambient noise requirements and guidance on measurement uncertainty to ensure consistent, repeatable assessment of conducted and radiated disturbance relevant to external receivers.

Scope

The standard amends CISPR 36:2020 to refine the methods and limits used to evaluate radio disturbance from electric and hybrid road vehicles that could affect external (off‑board) receivers operating below 30 MHz. It addresses measurement arrangements, detectors and timing, ambient noise conditions, definitions relevant to modern vehicle power systems (for example REESS and high‑voltage circuitry), and provides guidance on measurement uncertainty so that results are comparable across test laboratories and jurisdictions. The amendment is intended for use where protection of off‑board radio services is required.

Key topics and requirements

• Limits for radio disturbance (emissions) from electric and hybrid road vehicles relevant to off‑board receivers below 30 MHz.
• Measurement methods and test arrangements for conducted and near‑field emissions relevant to external receivers.
• Updated definitions, including rechargeable energy storage systems (REESS) and criteria for high‑voltage systems (>60 V) in vehicles.
• Detector types, timing and measurement procedures to ensure repeatable results (including specified detectors and dwell/timing rules).
• Requirements for ambient noise considerations and how to treat background interference during testing.
• Guidance on estimating and reporting measurement uncertainty and applying it to compliance decisions.
• Alignment and national/adopted versions (EN IEC 55036 series and regional adoptions) for regulatory and market use.

Typical use and users

Manufacturers and test laboratories for electric and hybrid road vehicles use this amendment when assessing whether vehicle emissions may interfere with external radio receivers (for example, AM broadcast, maritime or land mobile services below 30 MHz). Regulatory bodies, certification bodies and standards committees reference the document when establishing or harmonizing EMC requirements for vehicles and when adopting national or regional versions (for example EN IEC 55036/A1). Test engineers, EMC specialists, and compliance managers in automotive OEMs and tier‑1 suppliers are the primary users.

Related standards

Related documents and series include the base CISPR 36:2020 publication (the main document amended by this 2023 release), EN IEC 55036:2020 and EN IEC 55036:2020/A1:2023 (European adoption of CISPR 36 with Amendment 1), and other CISPR publications that address vehicle and automotive EMC (for example CISPR 12 and CISPR 25 for in‑vehicle and component emissions). National adoptions and harmonized regional versions are published by standards bodies (CENELEC, DIN, EVS, etc.).

FAQ

Q: What is this standard?

A: CISPR 36:2020/AMD1:2023 is Amendment 1 (published 17 May 2023) to the CISPR 36 standard, which defines radio disturbance limits and measurement methods for electric and hybrid road vehicles intended to protect off‑board receivers below 30 MHz.

Q: What does it cover?

A: It updates limits, measurement detectors and timing, definitions (including REESS and high‑voltage considerations), ambient noise treatment and guidance on measurement uncertainty for tests assessing emissions from vehicles that could affect external radio receivers.

Q: Who typically uses it?

A: Vehicle manufacturers, component suppliers, EMC test laboratories, certification and regulatory bodies, and standards committees that develop/adopt vehicle EMC requirements for protection of off‑board radio services.

Q: Is it current or superseded?

A: The 2023 amendment (CISPR 36:2020/AMD1:2023) is a current published amendment to CISPR 36:2020 intended to be used alongside the 2020 edition; it is not a full superseding replacement but an update to that edition. National and regional adoptions (EN IEC 55036/A1, etc.) reflect the amendment in local standards collections.

Q: Is it part of a series?

A: Yes — CISPR 36 is part of the CISPR series of publications addressing radio‑frequency disturbance and EMC for vehicles and equipment. It is associated with EN IEC 55036 (European adoption) and sits alongside other CISPR standards relevant to automotive EMC (for example CISPR 12 and CISPR 25).

Q: What are the key keywords?

A: Electric and hybrid road vehicles, radio disturbance characteristics, off‑board receivers, below 30 MHz, measurement methods, emission limits, REESS, high voltage, measurement uncertainty, EN IEC 55036.
