EN 55032 (CISPR 32)
EN 55032 is the European harmonized standard for electromagnetic compatibility (EMC) of multimedia equipment (MME), published by CENELEC. It is technically identical to CISPR 32, an international standard developed by the International Special Committee on Radio Interference (CISPR) under the IEC.
The standard sets emission limits and test methods to ensure that multimedia equipment does not cause harmful interference in residential, commercial, or light-industrial environments.
Scope and Application
EN 55032 applies to a broad range of multimedia and information technology equipment, including:
Set-top boxes, smart TVs, and streaming devices
Gaming consoles and computer systems
Audio and video players
Broadcast receivers and integrated multimedia systems
It distinguishes between two categories:
Class A equipment: Devices intended for industrial environments. They may generate higher disturbance levels and are unsuitable for residential use without additional measures.
Class B equipment: Devices intended for residential, commercial, and light-industrial environments. They must meet stricter limits to avoid interference in sensitive environments.
Immunity requirements are not part of EN 55032; these are defined in EN 55035 (CISPR 35).
Key Technical Requirements
| Parameter | Limits & Requirements |
|---|---|
| Conducted emissions (Quasi-Peak, QP) |
Class A: 79–73 dBµV Class B: 66–56 dBµV Range: 150 kHz – 30 MHz |
| Radiated emissions @ 10 m |
Class A: 40 dBµV/m Class B: 30 dBµV/m Range: 30 – 230 MHz |
| Radiated emissions @ 10 m |
Class A: 47 dBµV/m Class B: 37 dBµV/m Range: 230 – 1,000 MHz |
| Radiated emissions >1 GHz (3 m) |
Class A: 70 dBµV/m (peak), 50 dBµV/m (average) Class B: 70 dBµV/m (peak), 50 dBµV/m (average) Range: 1 – 6 GHz (typical) |
| Parameter | Class A | Class B | Frequency Range |
|---|---|---|---|
| Conducted emissions (Quasi-Peak, QP) | 79–73 dBµV | 66–56 dBµV | 150 kHz – 30 MHz |
| Radiated emissions @ 10 m | 40 dBµV/m | 30 dBµV/m | 30 – 230 MHz |
| Radiated emissions @ 10 m | 47 dBµV/m | 37 dBµV/m | 230 – 1,000 MHz |
| Radiated emissions >1 GHz (3 m) | 70 dBµV/m (peak), 50 dBµV/m (average) | 70 dBµV/m (peak), 50 dBµV/m (average) | 1 – 6 GHz (typical) |
- Measurement distances: typically 3 m, 10 m, or 30 m depending on equipment size and test site.
- Port-specific limits: Different requirements apply to mains ports, telecom ports, and broadcast input ports.
- Measurement standards: Methods and instrumentation follow the CISPR 16 series.
Typical Test Setup
Conducted emissions: Line Impedance Stabilization Network (LISN) + EMI receiver
Radiated emissions: Semi-anechoic chamber, spectrum analyzer or EMI receiver, bilog or horn antennas
Test environment: Equipment Under Test (EUT) operated in worst-case modes to capture maximum disturbance levels
Certification and Compliance
Under the EMC Directive (2014/30/EU), EN 55032 is a harmonized standard used to demonstrate conformity with emission requirements.
Only in combination with EN 55035 (CISPR 35) does EN 55032 provide a complete EMC assessment for CE marking, since EN 55032 covers emissions and EN 55035 covers immunity.
Test reports must be retained and referenced in the EU Declaration of Conformity (DoC).
Lifecycle Relevance
Supports pre-compliance testing during R&D to identify emission problems early.
Forms the basis for final EMC certification required for CE marking.
Remains applicable for product updates or re-designs that may affect emission behavior.
