What is IEC 61000-4-104:2019 ?

Title: IEC 61000-4-13:2019 - An International Standard for Electromagnetic Compatibility Testing

Introduction:

Electromagnetic compatibility (EMC) is a crucial aspect of the development and use of electrical and electronic equipment. It is essential to ensure that these products function correctly and efficiently in the presence of electromagnetic interference (EMI) from various sources. IEC 61000-4-13:2019 is an international standard that provides guidelines for conducting EMC testing for electrical and electronic equipment. In this article, we will discuss the purpose and testing process of IEC 61000-4-13:2019.

Purpose of IEC 61000-4-13:2019:

The main purpose of IEC 61000-4-13:2019 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 fields. The standard aims to ensure that products are capable of operating without being affected by electromagnetic interference from radio transmitters or other sources.

Testing Process:

IEC 61000-4-13:2019 provides guidelines for conducting EMC testing for electrical and electronic equipment. The testing process typically includes the following steps:

Definition of the electromagnetic environment (EME)

Configuration of the equipment for testing

(Exposure Testing)

(Simulation Testing)

(Data Analysis)

(Test Report)

The standard defines four test levels, which are designed to simulate different levels of electromagnetic interference (EMI) from various sources. These test levels are:

a. MF1 (Mainsignalling at a.c. power port, low frequency)

b. MF2 (Mainsignalling at a.c. power port, high frequency)

c. IF1 (Interference from a.c. power lines, low frequency)

d. IF2 (Interference from a.c. power lines, high frequency)

Scope:

IEC 61000-4-13:2019 covers a wide range of electromagnetic interference (EMI) sources, including but not limited to:

Radio transmitters

Wireless devices

Communications equipment

Audio and video equipment

Computers and other electronic devices

Conclusion:

IEC 61000-4-13:2019 is an essential international standard for EMC testing of electrical and electronic equipment. It provides guidelines for conducting tests, test levels, and evaluation criteria to ensure that devices can function properly in the presence of electromagnetic interference. By subjecting electrical and electronic equipment to these tests, manufacturers can assess the performance and susceptibility of their products to electromagnetic fields, and ensure that they meet the necessary standards for operation.
