Title: Understanding EN 61000-4-5 and EN 61000-4-6:1995

Introduction:

EN 61000-4-5 and EN 61000-4-6:1995 are two essential international standards that cater to the requirements of electrical and electronic equipment for surge immunity testing and electromagnetic compatibility (EMC), respectively. These standards provide guidelines for testing the immunity of equipment against various types of voltages and fields, ensuring that the equipment can withstand the challenges it may face in different environments.

What is EN 61000-4-5:1995?

EN 61000-4-5:1995 is a standard developed by the International Electrotechnical Commission (IEC) to evaluate the immunity of electrical and electronic equipment against surge voltages. This standard outlines a range of test methods and criteria for testing the performance of equipment in various scenarios, such as industrial, residential, and commercial environments.

The standard defines four categories of surge voltages, which are:

* Class A: Direct contact with a person

* Class B: Direct contact with a person and indirect contact with an electrical equipment

* Class C: Indirect contact with a person and indirect contact with an electrical equipment

* Class D: No contact with a person or electrical equipment

Each category is assigned a specific voltage level (0V, 50V, 100V, or 150V), which is used to simulate various types of surges, such as those caused by lightning strikes, power fluctuations, or equipment malfunctions.

The standard also provides guidelines for conducting the tests, including the frequency of the surges, the duration of the exposure, and the testing procedures for different categories of surges. Additionally, the standard specifies the criteria for determining the immunity of the equipment, such as the equipment's ability to remain operational and free from damage after the test.

What is EN 61000-4-6:1996?

EN 61000-4-6:1996 is an international standard that focuses on the issue of electromagnetic compatibility (EMC) and specifically addresses conducted disturbances induced by radio-frequency fields in the frequency range of 150 kHz to 80 MHz.

This standard provides guidance and defines measurement techniques for assessing the immunity of electrical and electronic equipment to these disturbances. The standard covers various aspects, including the testing procedures, the measurement equipment, and the classification of the equipment based on its immunity level.

The standard also defines the criteria for determining the immunity of the equipment, such as the equipment's ability to remain operational and free from damage after the test. Additionally, the standard specifies the testing procedures for conducted disturbances, including the frequency and duration of the disturbance, the distance between the equipment and the source of the disturbance, and the type of equipment being tested.

Conclusion:

In conclusion, EN 61000-4-5 and EN 61000-4-6:1995 are two crucial international standards that outline the requirements for testing the immunity of electrical and electronic equipment against surge voltages and electromagnetic compatibility, respectively. These standards provide guidelines for conducting the tests, including the frequency of the surges, the duration of the exposure, and the criteria for determining the immunity of the equipment. By adhering to these standards, manufacturers can ensure that their equipment is reliable, safe, and reliable in various environments.
