What is the difference between ISO 10605 and IEC 61000-4-2?

The field of electromagnetic compatibility (EMC) is crucial in ensuring that electronic devices can function properly without interference from electromagnetic radiation. To regulate EMC, there are several standards and test methods available, including ISO 10605 and IEC 61000-4-2. In this article, we will explore the main differences between these two standards.

of ISO 10605

ISO 10605 is an international standard that specifically focuses on Electrostatic Discharge (ESD) immunity testing for electronic devices. ESD occurs when two objects with different electrical charges come into contact or close proximity, resulting in the sudden transfer of electricity. This standard specifies test methods to assess the susceptibility of electronic devices to ESD and establishes threshold levels for acceptable immunity.

ISO 10605 consists of different test levels that simulate various ESD scenarios to which electronic devices might be exposed in real-world environments. These test levels are determined based on the expected discharge conditions, such as contact discharge and air discharge. The standard also provides guidelines on testing procedures and equipment calibration requirements.

of IEC 61000-4-2

IEC 61000-4-2 is part of a series of standards developed by the International Electrotechnical Commission (IEC) to address electromagnetic compatibility issues. It covers testing and measurement techniques for ESD immunity of electronic equipment in laboratory and manufacturing environments.

Compared to ISO 10605, IEC 61000-4-2 focuses on a broader range of EMC-related topics, including immunity to ESD, as well as radiated and conducted disturbances caused by electromagnetic fields. While ISO 10605 provides specific test levels and discharge conditions, IEC 61000-4-2 offers more comprehensive guidelines for evaluating the overall EMC performance of electronic equipment.

Differences between ISO 10605 and IEC 61000-4-2

1. Scope: ISO 10605 primarily concentrates on ESD immunity testing, whereas IEC 61000-4-2 covers a wider range of disturbances caused by electromagnetic fields.

2. Test Levels: ISO 10605 provides specific test levels for different types of ESD discharges, while IEC 61000-4-2 establishes general classification levels for various EMC immunity tests.

3. Application: ISO 10605 is commonly used in automotive, aerospace, and consumer electronics industries where ESD protection is critical. IEC 61000-4-2 is more widely applicable to different electronic systems due to its broader scope.

In conclusion, both ISO 10605 and IEC 61000-4-2 play significant roles in ensuring the electromagnetic compatibility of electronic devices. However, ISO 10605 specifically addresses ESD immunity testing, while IEC 61000-4-2 covers a broader range of electromagnetic disturbances. Selecting the appropriate standard depends on the specific requirements of the industry and intended use of the electronic equipment.
