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

The series of standards is subdivided into 6 parts, covering different aspects of the railway environment. Emission of the whole railway system to the outside world Status: The technical difficulties of making EMC measurements on moving trains have been addressed and a cost effective solution referred to. Search 501221-2 products by. Some of the more common standards for rail applications we can help you with include:.

EN 50121-2:2006

The railway presents a complex electromagnetic environment made up of many systems including signalling, traction, telecommunications and radiocommunications. 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 Sorry, your blog cannot share posts by email.

So the questions remaining are: The railway clearly meets the definition of a fixed installation.

Some of the more common standards for rail applications we can help you with include: This series describes the EMC requirements for the rail sector and includes the following standards:. Electromagnetic compatibility forms an essential part of these processes.

This European Standard specifies the emission limits of the whole railway system to the outside world. Electromagnetic compatibility Emission and immunity of the signalling and telecommunications apparatus BS EN In many cases, these national standards build on the requirements of EN such that the resulting standard more adequately reflects the requirements of a particular part of the railway.

Emission and immunity of the signalling and telecommunications apparatus EN Railway applications — Electromagnetic compatibility — Part 5: It is all too apparent that interference from traction power equipment may affect the signalling system with potentially dire consequences. Some of the more common standards for rail applications we can help 51021-2 with.

Similarly the IEC x series of standards represents what can be agreed at an international level. Shopping Cart Your shopping cart is empty.

Consulting Testing Certification News About us. Where products are too physically large to be assessed in a test chamber, we can test in situ. It wn 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.

EMC tests according to the standard series EN 50121

This standard mandates the requirements for the management of EMC between the railway infrastructure and trains to enable safe operation to be assured. Rolling stock — Train and complete vehicle EN Railway applications — Electromagnetic compatibility — Part 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: So in the UK, EMC is one of the requirements included in the Safety Case for the introduction of new rolling stock, locomotives or track maintenance vehicles onto the rail network.


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. It is vital that the installation practices must ensure that the integrity of the sub-system immunity is maintained, whether by using for example, screened cables, cable separation, or grounding and bonding techniques.

EN — Railway applications: MET Laboratories, Inc was established in and has become a global service leader for product approvals and regulatory certification of electrical products in Baltimore, MD.

At this stage it may simply define the EN x: Also, the zones above and below the railway system may be affected by electromagnetic emissions and particular cases need to be considered individually. It is then necessary for the system manufacturer to validate, from an EMC viewpoint, the installation and wiring techniques he has used. 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 This is consistent with the EN standards [4], which cover all the constituent parts of the railway.

WLAN access points, ticket machines, train displays monitors might fall — in case the use of radio interfaces — also under the radio equipment directive. The NRTL mark is required under federal law for products used in workplaces in all 50 states. Get A Quote Today.
