What is EN 46371?

Introduction

EN 46371 is a technical standard that specifies the requirements for testing and measuring the immunity of electrical and electronic equipment to electromagnetic disturbances. It is an essential standard in ensuring the functionality and reliability of various devices in the presence of electromagnetic radiation.

Scope and Purpose

The primary objective of EN 46371 is to evaluate the performance of equipment when subjected to electromagnetic fields. This standard establishes test methods to determine the immunity levels of equipment against conducted, radiated, and transient electromagnetic disturbances. By complying with EN 46371, manufacturers can ensure that their products meet the necessary electromagnetic compatibility requirements.

Testing Methods

EN 46371 provides detailed guidelines for conducting tests on equipment. These tests include both conducted and radiated immunity tests, as well as tests for electrostatic discharge (ESD), fast transient/burst, and surge immunity. Each type of test has specific parameters and test setups defined by the standard.

Conducted immunity tests involve exposing the equipment to conducted disturbances through power supply or signal cables. Radiated immunity tests, on the other hand, simulate exposure to electromagnetic fields from various sources such as radio transmitters or electrical substations.

Conclusion

EN 46371 plays a crucial role in ensuring that electrical and electronic devices can function properly in environments with electromagnetic disturbances. Compliance with this standard helps manufacturers produce reliable products that are less likely to experience malfunctions caused by electromagnetic interference.

By adhering to the testing methods specified in EN 46371, manufacturers can demonstrate the immunity of their equipment to electromagnetic disturbances and provide assurance to consumers regarding the quality and reliability of their products.

In conclusion, EN 46371 serves as a valuable tool in the design, development, and testing of electrical and electronic equipment. It enables manufacturers to meet the required standards for electromagnetic compatibility and ensures that devices can operate effectively in today's increasingly complex electromagnetic environments.
