IEC 61000-4-2 Electrostatic Discharge Immunity Testing: Eurolabs Laboratory Testing Service

The IEC 61000-4-2 standard is a widely recognized and accepted international standard for electrostatic discharge immunity testing. This standard, published by the International Electrotechnical Commission (IEC), provides guidelines for testing electrical devices against the effects of electrostatic discharges (ESD). The standard is part of the IEC 61000 series, which deals with electromagnetic compatibility (EMC) and immunity testing.

Legal and Regulatory Framework

The legal and regulatory framework surrounding IEC 61000-4-2 testing is complex and multifaceted. Various national and international standards bodies, such as ISO, ASTM, EN, TSE, and others, have adopted or referenced the IEC 61000-4-2 standard in their respective documents. These standards are used to ensure that electrical devices comply with safety and regulatory requirements.

International and National Standards

The following standards apply to IEC 61000-4-2 testing:

  • IEC 61000-4-2:2008 (Electromagnetic compatibility (EMC) - Part 4-2: Testing and measurement techniques - Electrostatic discharge immunity test)

  • ISO/IEC 17025:2017 (General requirements for the competence of testing and calibration laboratories)

  • EN 61000-4-2:2009 (Electromagnetic compatibility - Part 4-2: Testing and measurement techniques - Electrostatic discharge immunity test)

  • ASTM D6134-11 (Standard Test Method for Evaluating the Performance of Electromagnetic Interference (EMI) Filters)

    • Standard Development Organizations

    The IEC is a non-profit, independent organization that develops and publishes international standards. The IEC has over 80 member countries and works closely with other standard development organizations, such as ISO, ASTM, and EN.

    Evolution of Standards

    Standards evolve and get updated to reflect changes in technology, safety requirements, and regulatory needs. The IEC reviews and updates its standards regularly to ensure they remain relevant and effective.

    Standard Numbers and Scope

    The following standard numbers and scope are relevant to IEC 61000-4-2 testing:

  • IEC 61000-4-2:2008 (Electromagnetic compatibility (EMC) - Part 4-2: Testing and measurement techniques - Electrostatic discharge immunity test)

    • Applies to electrical devices that require protection against electrostatic discharges
