What is BS EN 61439-2:2018 ?

Title: A Comprehensive Guide to BS EN 61439-2:2018 and BS EN 166:2020

The advancement of electric vehicles (EVs) has created a growing demand for high-quality, reliable, and safe EV charging infrastructure. To meet these demands, manufacturers need to develop and implement EV charging standards that ensure compatibility, reliability, and user safety. Two such standards that are of particular interest to EV manufacturers and users are BS EN 61439-2:2018 and BS EN 166:2020.

In this article, we will provide a comprehensive guide to these two important standards, including their scope, key requirements, and how they can contribute to the development of a safer and more efficient EV charging infrastructure.

Overview of BS EN 61439-2:2018:

BS EN 61439-2:2018 is a European standard that outlines the dimensions and tolerances for plugs, socket-outlets, vehicle connectors, and vehicle inlets used in EV charging systems. The primary objective of this standard is to ensure interoperability between EV charging infrastructure components, regardless of the manufacturer.

The standard defines the physical dimensions and tolerances for a range of electrical components, including AC and DC plugs, sockets, and connectors. It also specifies the materials that can be used for these components, as well as the testing procedures that need to be followed to ensure compliance.

The key requirements of BS EN 61439-2:2018 include:

* Dimensional compatibility: The standard defines the dimensions and tolerances for EV charging components, including the width, height, and depth. It also specifies the number of turns and the voltage and amperage ratings that can be used.

* Interchangeability: The standard specifies the tests that need to be performed to ensure that components from different manufacturers can be interchangeable.

* Performance: The standard outlines the testing procedures that need to be followed to ensure that EV charging components meet the requirements for performance, including tests for electrical continuity, insulation resistance, and voltage drop.

Overview of BS EN 166:2020:

BS EN 166:2020 is a European standard that outlines the specifications and testing methods for personal eye protectors. It applies to all types of eye protectors used for general occupational applications, including those designed to provide protection against optical radiation, liquid droplets, mechanical hazards, and more.

The standard defines the various parameters that need to be met to ensure the quality and performance of eye protectors, including the field of vision, optical characteristics, resistance to ignition, robustness, compatibility with other PPE, and more. Manufacturers need to comply with these requirements to obtain certification for their eye protectors.

The key requirements of BS EN 166:2020 include:

* Safety: The standard outlines the various safety requirements that must be met to ensure that eye protectors are safe to use, including requirements for impact resistance, chemical resistance, and electrical safety.

* Performance: The standard outlines the various performance requirements that must be met to ensure that eye protectors provide effective protection against various hazards, including requirements for the reduction of the risk of eye injury or damage.

* Testing: The standard outlines the various testing requirements that must be met to ensure that eye protectors meet the requirements for quality and performance.

Conclusion:

BS EN 61439-2:2018 and BS EN 166:2020 are important standards that can contribute to the development of a safer and more efficient EV charging infrastructure. By defining the dimensions and tolerances for EV charging components and the safety requirements for eye protectors, these standards ensure that EVs can be charged safely and effectively.
