Consulting Testing Certification News About us. Some of the more common standards for rail applications we can help you with include:. Our capabilities enable us to test to the highest levels required by the EN series of standards.

Your basket is empty. It is also necessary to control the design process to ensure that the documentation is produced which will support and be included within the Safety Case to cover the EMC aspects of safety and which will enable the manufacturer to declare conformance with appropriate EMC regulations.

The intention of EN was that it would be a product performance standard rather than a standard used for CE marking purposes; that was the remit of EN Take the smart route to manage medical device compliance. Some of the more common standards for rail applications we can help you with include: If you continue to use this website without changing your cookie settings or you click “Accept” below then you are consenting to this.

This series describes the EMC requirements for the rail sector and includes the following standards:. InMET broke the UL monopoly for product safety testing and certification in the United States and is approved to certify products in over UL standard categories.

It is therefore essential to manage EMC to meet the technical, safety and legal requirements from project concept by implementing an EMC Management Plan.

The European EN parts [4] were introduced in as pre-standards, were ne in and the version became fully effective from July Search all products by.

EMC tests according to the standard series EN – CETECOM™

Full text browsing Price: This means that transient emissions, such as those due to pantograph bounce or shoegear gapping are included in the 501121-2 measurement. Immunity testing may be largely impractical on-site for large systems and reliance must be placed on the integrity rn the immunity testing performed on the individual items of apparatus or systems and the installation practices used.

As part of our test services for EMCwe offer tests in accordance with the EN x series of standards. This European Standard is intended to define the electromagnetic environment of the whole railway system including urban mass transit and light rail system. Railway We have experience with a wide range of standards and regulations.

These emissions should be assumed to exist at all points in the vertical planes which are 10 m from the centre lines of the outer electrified railway tracks, or 10 m from the fence of the substations. Conclusions For EMC assurance for equipment or large installed systems, within the railway environment, a practical approach has been described which relies on rigorous testing of sub-systems and the verification of installation and design practices by a combination of managing EMC from the outset, QA procedures and whole system emission testing accepting practical limitations.

For a large system, whilst it will be necessary to perform some EMC measurements on the whole system, initially it is necessary to identify the various electrical sub-systems and determine the procurement policy from suppliers.

Electromagnetic compatibility forms an essential part of these processes. Product evaluation and creation of appropriate test plans Product testing and certification at component and system level in the lab or field Conducting on-site EMI field surveys or safety field evaluations Environmental simulation: Manufacturers may assess their products against the EN series of standards as a means of demonstrating compliance with the Directive.

50121–2 a FI is identified as an unacceptable source of emissions, a Competent Authority can request that the responsible person bring it into compliance with the protection requirements. It is then necessary for the system manufacturer to validate, from an EMC viewpoint, the installation and 500121-2 techniques he has used. Emission of the whole railway system to the outside world EN Railway applications — Electromagnetic compatibility — Part It must be stressed that the railway EMC standards represent the minimum technical requirement and that additional measures may need to be taken on the basis of the hazard identification and risk closure.

Rolling stock — Train and complete vehicle EN Railway applications — Electromagnetic compatibility — Part EN comprises the following parts: For an electrified railway, Megawatts of power are required to be converted into the propulsion of trains in order to transport passengers or freight from one destination to another.

EVS-EN 50121-2:2017

For newly build railway systems it is best practice to provide compliance to the emission limits given in this part of the standard as defined in the EMC plan according to EN EN Railway applications — Electromagnetic compatibility — Part 1: The manufacturer may choose to either follow conformity assessment procedures or to provide accompanying documentation detailing the name and site of the FI and the EMC precautions 500121-2 be taken for the incorporation em the apparatus in order to maintain the conformity of the installation.

Enforcement action seems unlikely, since Competent Authorities have shown little appetite to enforce the EMC requirements for products.
