What is IEC 61000-4-107: 2019 ?

Title: Understanding IEC 61000-4-107: 2019: A Technical Article on Electromagnetic Compatibility and Interference

IEC 61000-4-107: 2019 is an essential standard for evaluating the electromagnetic compatibility (EMC) of electrical and electronic equipment. This international standard is developed by the International Electrotechnical Commission (IEC) and focuses on ensuring the proper functioning of devices in the presence of electromagnetic interference (EMI) from various sources. In this article, we will delve into the details of IEC 61000-4-107: 2019, including its scope, purpose, and testing process.

What is IEC 61000-4-13: 2019?

IEC 61000-4-13: 2019, also known as "Electromagnetic compatibility (EMC) - Part 4-13: Testing and measurement techniques - Harmonics and interharmonics including mains signalling at a.c. power port, low frequency immunity tests, " is a widely recognized international standard developed by the IEC. This standard is designed to establish guidelines for testing and measuring the electromagnetic compatibility (EMC) of electrical and electronic equipment.

The standard focuses on harmonics and interharmonics, which are disturbances caused by non-sinusoidal electrical waveforms that can affect the performance of connected devices. To achieve this, the standard defines a set of conditions that simulate realistic electromagnetic environments. These tests are used to evaluate the performance and susceptibility of products to electromagnetic interference from various sources, including radio transmitters.

What is IEC 61000-4-1: 2019?

IEC 61000-4-1: 2019 is an essential international standard related to the testing and measurement techniques used for EMC. This standard specifically focuses on immunity tests for electrical and electronic equipment against electromagnetic fields caused by radio transmitters. It provides guidelines for conducting the tests, test levels, and evaluation criteria to ensure that devices can function properly in the presence of electromagnetic interference.

The Purpose of IEC 61000-4-1: 2019

The main purpose of the IEC 61000-4-1: 2019 standard is to define a set of conditions that simulate realistic electromagnetic environments. By subjecting electrical and electronic equipment to these tests, manufacturers can assess the performance and susceptibility of their products to electromagnetic interference from radio transmitters or other sources. The standard aims to ensure that products are capable of operating without being affected by electromagnetic interference from these sources.

The Testing Process:

To evaluate the EMC performance of a product, manufacturers must conduct various tests, including IEC 61000-4-1: 2019, to ensure that their products meet the relevant EMC standards. These tests are typically conducted in an anechoic chamber, which is a specialized environment designed to minimize interference from external sources.

The testing process typically consists of several steps, including:

Selecting the appropriate test method according to the product's specifications.

Designing an anechoic chamber to ensure proper shielding.

Conducting the test in the anechoic chamber.

Measuring and analyzing the test results.

Reporting the test results to the manufacturer.

Conclusion:

IEC 61000-4-107: 2019 is an essential standard for evaluating the EMC of electrical and electronic equipment. This standard defines a set of conditions that simulate realistic electromagnetic environments and provides guidelines for conducting tests to ensure that products are capable of operating without being affected by electromagnetic interference from various sources. By subjecting their products to these tests, manufacturers can assess the overall EMC performance of their products and ensure that they meet the relevant EMC standards.
