What is EN ISO 12405-2: 2018 ?

Title: A Comprehensive Guide to EN ISO 12405: 2021 and EN ISO 31105: 2018

EN ISO 12405: 2021 and EN ISO 31105: 2018 are two of the most significant technical standards that have gained widespread attention in recent years. These standards are designed to ensure the safety, quality, and performance of various products, including electric vehicles and charging infrastructure. In this article, we will provide a comprehensive guide to these two standards, including their purpose, key features, and how they impact different industries.

What is EN ISO 12405: 2021?

EN ISO 12405: 2021 is a technical standard that outlines the requirements for the design, performance, and safety of electrical connectors for electric vehicles. This standard is developed by the European Committee for Standardization (CEN) and International Organization for Standardization (ISO) and is widely recognized as the benchmark for the industry.

The primary objective of EN ISO 12405: 2021 is to establish clear and standardized practices for the preparation of technical drawings, diagrams, and documentation related to electrical connectors for electric vehicles. The standard provides guidelines on various aspects, such as the requirements for the material, dimensions, and performance of electrical connectors. It also specifies the test procedures that need to be performed to ensure the compliance of the products with the relevant requirements.

Key Elements of EN ISO 12405: 2021

EN ISO 12405: 2021 is divided into several sections, each of which covers a different aspect of the electrical connector design. Some of the key elements of this standard include:

Electrical Characteristics: This section outlines the technical requirements for the electrical characteristics of the electrical connector, such as voltage, current, and resistance.

Design and Modelling: This section provides guidelines on the design and modeling of electrical connectors, including the, .Test Methods: This section specifies the test procedures that need to be performed to evaluate the electrical connectors, such as the hot-plug test, overload test, and short-circuit test.

Electrical Safety: This section outlines the requirements for the electrical safety of the electrical connector, including the need for adequate insulation, grounding, and labeling.

What is EN ISO 31105: 2018?

EN ISO 31105: 2018 is an international standard that outlines the requirements for the preparation of technical drawings and documentation related to the design of electrostatic discharge protection (ESD) and gas discharge protection (GD) systems for electrical equipment. This standard is developed by the European Committee for Standardization (CEN) and International Organization for Standardization (ISO) and is designed to ensure the consistency and reproducibility of ESD and GD system designs.

The primary objective of EN ISO 31105: 2018 is to provide guidance on the preparation of technical drawings and documentation for ESD and GD systems, including the symbols, dimensions, and descriptions that should be used. The standard aims to ensure that the technical drawings and documentation are clear and consistent across different industries and countries.

Key Elements of EN ISO 31105: 2018

EN ISO 31105: 2018 is divided into several sections, each of which covers a different aspect of the preparation of technical drawings and documentation for ESD and GD systems. Some of the key elements of this standard include:

symbols and dimensions: This section provides guidelines on the symbols and dimensions that should be used in the technical drawings and documentation for ESD and GD systems, including the symbols for different types of devices, the dimensions of different components, and the use of metric units.

Description of the system: This section outlines the information that should be included in the technical drawings and documentation.
