The E-mark in Public Transport

Within the realm of public transport, the E-mark certification ensures that road vehicles and their installed components adhere to the stringent safety and environmental standards mandated by the UN/ECE regulations. This certification encompasses electronic subassemblies, including Ethernet switches, which are among the components governed by these standardized technical regulations. The E-mark is directly affixed to the vehicle or the relevant component, signifying its type approval. This recognition holds international validity.

What is the E-Mark and How Does It Work?

The E-Mark, also known as the E-Plate or ECE Mark, was established by the United Nations Economic Commission for Europe (ECE). It represents a standardized system of vehicle design regulations that apply to both the European Economic Area (EEA) and worldwide.

The mark consists of a capital “E” enclosed in a circle, along with a numerical code indicating the country of approval (e.g., E1 for Germany, E2 for France, E5 for Sweden). Components bearing this E-Mark have undergone testing and are deemed compliant, allowing their use in all countries participating in the ECE procedure without further evaluation.

Difference to the e-Mark

In addition to the E-Mark, there is also the e-Mark, which is based on guidelines from the European Commission and establishes a unified set of regulations for all EU member states. It is represented by a small e and a test number in a rectangle. While the e-Mark covers similar requirements, the E-Mark has global applicability and enjoys wider recognition.

The Significance of the E-Mark in Public Transport

The E-Mark offers several key advantages in the field of public transport:

  1. International Acceptance: Products featuring the E-Mark can be utilized not only within the EU but also in numerous non-European countries. These countries often align their conformity requirements with those of the EU, accepting E-Test reports as evidence of compliance and eliminating the need for additional testing and assessment.
  2. Safety and Reliability: The E-Mark ensures that relevant components meet the stringent safety standards outlined in the UN/ECE regulations, promoting passenger safety and environmental protection.
  3. Efficiency and Streamlining: The utilization of E-Mark-certified components significantly simplifies the approval process for public transport vehicles. As these components have already undergone testing and received approval, there is no need for costly additional tests and certifications.

E1-Certified M12 Ethernet Switches for Public Transport

The E-Mark is particularly significant when installing switches in city buses. These devices must meet specific requirements, such as electromagnetic compatibility according to UN/ECE R10 and fire safety requirements in accordance with UN ECE R118.

ROQSTAR M12 Ethernet switches are specifically designed for use in public transport and bear the E1 certification mark. This certification confirms their suitability for installation in road vehicles, ensuring a secure and reliable network infrastructure within public transport buses.
