What is BS EN 61937-9: 2018 ?

Title: A Comprehensive Guide to BS EN 61937-9: 2018: The Ultimate Standard for Fire Resistance in Building Elements

Building structures are designed to be fire-resistant to ensure the safety of occupants and the property. The British Standard 476 Part 20 (BS476: Part 20) is a widely recognized standard for determining the fire resistance of building elements such as walls, floors, and doors. However, the relevance of this standard in today's construction industry is worth exploring.

BS EN 61937-9: 2018, also known as Plugs, socket-outlets, vehicle connectors and vehicle inlets – Conductive charging of electric vehicles – Part 2: Dimensional compatibility and interchangeability requirements for a.c. pin and contact-tube accessories, is a significant standard that addresses the dimensional compatibility and interchangeability requirements for alternating current (a.c.) pin and contact-tube accessories used in electric vehicle (EV) charging systems.

The primary objective of BS EN 61937-9: 2018 is to ensure interoperability between EV charging infrastructure components, regardless of the manufacturer. By defining the physical dimensions and tolerances for plugs, socket-outlets, vehicle connectors, and vehicle inlets, this standard enables easy and reliable connections between EVs and charging stations.

Purpose of the Article:

This technical article aims to provide a comprehensive understanding of BS EN 61937-9: 2018 and its relevance in today's construction industry. We will discuss the purpose of the standard, its scope, and how it relates to the fire resistance of building elements.

Measuring Fire Resistance:

BS476: Part 20 specifies the requirements for determining the fire resistance of various elements found within buildings such as walls, floors, and doors. The standard sets out the procedures for conducting fire tests to evaluate the time period that an element can withstand fire exposure without compromising its structural integrity.

However, fire resistance is not the only factor that should be considered when selecting building elements. Other factors such as durability, cost, and ease of maintenance should also be taken into account.

BS EN 62196-2: 2017: The Dimensional Compatibility and Interchangeability Requirements for EV Charging Infrastructure

BS EN 62196-2: 2017 is another significant standard that relates to EV charging infrastructure. This standard defines the physical dimensions and tolerances for EV charging components such as plugs, socket-outlets, vehicle connectors, and vehicle inlets.

The primary objective of BS EN 62196-2: 2017 is to ensure interoperability between EV charging infrastructure components, regardless of the manufacturer. By defining the dimensions and tolerances for EV charging components, this standard enables easy and reliable connections between EVs and charging stations.

Conclusion:

BS EN 61937-9: 2018 and BS EN 62196-2: 2017 are two significant standards that relate to fire resistance and EV charging infrastructure. These standards play a crucial role in ensuring the quality and safety of products. By defining the physical dimensions and tolerances for EV charging components, these standards enable easy and reliable connections between EVs and charging stations.

However, it is important to understand the context in which these standards are being used, and to consider other factors such as cost and maintenance when selecting building elements.

BS EN 61937-9: 2018 and BS EN 62196-2: 2017 are not just relevant for EV charging infrastructure; they also pertain to.
