Comprehensive Guide to IEC 61000-6-2 Generic Immunity Testing Laboratory Testing Service Provided by Eurolab

IEC 61000-6-2 is a standard that outlines the requirements for electromagnetic compatibility (EMC) testing of electrical and electronic equipment. This standard is part of the IEC 61000 series, which covers various aspects of EMC testing, including immunity testing. Immunity testing evaluates the ability of equipment to withstand electromagnetic interference (EMI) from external sources.

The legal and regulatory framework surrounding IEC 61000-6-2 testing is governed by international and national standards. In Europe, for example, the standard is referenced in the Low Voltage Directive (LVD), which requires manufacturers to ensure that their products comply with EMC requirements. Similarly, in the United States, the Federal Communications Commission (FCC) requires compliance with EMC regulations.

The IEC 61000-6-2 standard specifies the test methods and conditions for evaluating the immunity of electrical and electronic equipment to various types of electromagnetic interference, including radio-frequency (RF), electrostatic discharge (ESD), and power frequency magnetic fields. The standard also provides guidance on how to evaluate the susceptibility of equipment to EMI.

Standard development organizations play a crucial role in maintaining and updating standards like IEC 61000-6-2. These organizations include the International Electrotechnical Commission (IEC), the European Committee for Electrotechnical Standardization (CENELEC), and the American National Standards Institute (ANSI). They work together to develop and publish new standards, as well as revise existing ones.

Standards evolve over time due to advances in technology and changing regulatory requirements. For example, IEC 61000-6-2 has undergone several revisions since its initial publication in 2005. Each revision updates the test methods and conditions to reflect changes in EMC testing practices and regulatory requirements.

Specific standard numbers and their scope are as follows:

  • IEC 61000-6-2: Generic immunity testing

    • Scope: Specifies the test methods and conditions for evaluating the immunity of electrical and electronic equipment to various types of electromagnetic interference.

  • EN 61000-6-2: European Standard for generic immunity testing

    The level of the electromagnetic field is adjusted to simulate real-world scenarios.

    2. Conducted RF immunity test

    Equipment is connected to a network or other equipment and exposed to electromagnetic interference (EMI).

    3. ESD immunity test

    A charged device is brought close to the equipment under test, simulating an ESD event.

    Equipment under test must be representative of real-world usage conditions, including:

    1. Installation conditions: Equipment should be installed in a manner that simulates real-world use.

    2. Operating conditions: Equipment should operate under normal operating conditions during testing.

    3. Configuration: Equipment should be configured to simulate real-world usage scenarios.

    Test reports and documentation are essential for recording test results, including:

  • Test setup and configuration

  • Test levels and procedures

  • Results, including any deviations or anomalies

    • Conclusion
