Overview

EN 60939-2:2005/A1:2023 is a European standard specifying sectional requirements for passive filter units used in electromagnetic interference (EMI) suppression, with a focus on units subject to safety testing. This amendment to EN 60939-2:2005 incorporates the latest technical revisions from IEC 60939-2:2005/AMD1:2023 and was approved by the European Committee for Electrotechnical Standardization (CLC) in September 2023. It establishes test methods and general requirements ensuring the safety and performance of passive filter devices used to mitigate EMI in electrical and electronic equipment.

This standard is crucial for manufacturers, safety assessors, and regulatory bodies involved in the development, testing, and certification of passive filter units designed to suppress electromagnetic disturbances, particularly those for which safety testing is applicable. The regulation applies across various industries requiring stringent EMI control and protection, promoting interoperability and compliance with international safety standards.

Key Topics

• Scope and Definitions: Defines passive filter units specifically catering to EMI suppression and classifies filters based on their safety test applicability.
• Test Methods: Specifies procedures to evaluate the electrical, thermal, and mechanical safety performance of passive filters to ensure compliance with safety regulations.
• Safety Requirements: Outlines insulation criteria, creepage distances, clearances, and construction details particularly relevant for filters incorporating Class Y capacitors, which prevent electric shock hazards.
• Component Specifications: Provides updated norms for earth inductors, capacitors (including Class Y1, Y2, and Y4 types), and other passive components, ensuring filters meet designated voltage ratings and impulse withstand capacities.
• Normative References: Integrates related standards such as IEC 60335-1 (general safety requirements for electrical appliances), IEC 60384-14 (fixed capacitors for EMI suppression), and IEC 60939-1 (generic passive filter specifications), ensuring harmonized and comprehensive safety guidance.
• Amendment Highlights:
  • Clarification on earth inductor wire cross-section size requirements based on rated current.
  • Adjustments to insulation requirements referencing IEC 60664-1 for coordination within low-voltage supply systems.
  • Updated classification and testing procedures for Class Y capacitors ensuring enhanced electrical safety.
  • Refined compliance timelines and directives for national standard adoption and withdrawal of conflicting regulations.

Applications

EN 60939-2:2005/A1:2023 applies to passive EMI filter units widely used in:

• Electrical and electronic consumer appliances requiring electromagnetic compatibility (EMC) compliance.
• Industrial and medical equipment where EMI suppression is critical for operational safety and device reliability.
• Power supplies and distribution systems incorporating safety-tested passive filters to mitigate interference and withstand electrical surges.
• Systems requiring certified passive components that meet both performance and safety standards under various environmental conditions.
• Design and manufacture of filters bridging insulation types to safeguard against electric shock risks in compliance with international and European safety standards.

Adherence to this standard ensures that passive filter units perform reliably under normal and fault conditions while meeting essential safety metrics critical for user protection and product durability.

Related Standards

• EN 60939-1:2010 – Passive filter units for EMI suppression: Generic specifications, forming the foundational requirements applicable to all passive filter units.
• IEC 60335-1:2020 – Safety standards for household and similar electrical appliances covering general safety requirements relevant to the application of passive filters.
• IEC 60384-14:2023 – Fixed capacitors for electronic equipment: Sectional specification for capacitors used in EMI suppression and connection to supply mains, critical for Class Y capacitor classifications.
• IEC 60664-1 – Insulation coordination principles for electrical equipment operating at low voltages, referenced for defining insulation and clearance requirements.
• IEC 60938-1:2021 – Fixed inductors for electromagnetic interference suppression: Generic specification complementing the earth inductor requirements for passive filters.

These related standards form an integrated framework permitting manufacturers and testing authorities to design and evaluate EMI suppression filters safely and effectively, ensuring compatibility with European EMC and safety directives.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
