The advent of electricity prompted the signalling engineer to invent train detection systems within track sections, involving using the rail as an electrical conductor.

Railway Industry Testing for Electromagnetic Compatibility (EMC)

Also the standards require individual train passes for different frequency ranges, a time consuming and expensive operation, usually requiring the measurements to be made on a test track or on the network during a possession. As indicated by the management plan, 51021-2 supplier will be responsible for demonstrating that his equipment meets the EMC requirements specified and will submit his EMC Control Plan, Test Plans and Test Reports to the system contractor who will include these within the system EMC 501121-2 Documentation.

Emission of 50121-22 whole railway system to the outside world. Some of the more common standards for rail applications we can help you with include: This European Standard specifies the emission limits of the whole railway system to the outside world. This is consistent with the EN standards [4], which cover all the constituent parts of the railway.

BS EN 50121-2:2017

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.

For existing railway lines, it is assumed that compliance with the emission requirements of ENENEN and EN 5 will ensure the compliance with the emission values given in this part.

For existing build, the new EMC Directive is not retrospective. How will it be put into practice? Immunity testing may be largely impractical on-site for large systems and reliance must be placed on the integrity of the immunity testing performed on the individual items of apparatus or systems and the installation practices used.

Electronic equipment used on rolling stock is a standard which has caused much confusion over the years with manufacturers, ne because this standard too contains EMC requirements.

The Impact of the FI Requirements on the Railway Railway infrastructure controllers will need to appreciate the implications and implement policy. The technical difficulties of making EMC measurements on moving trains have been addressed and a cost effective solution referred to.

The key EMC problem 50112-2 the railway industry is the multi-use of the rail itself. Manufacturers may assess their products against the EN fn of standards as a means of demonstrating compliance with the Directive.

The latest versions of these LUL documents are respectively: More information about our full portfolio of test services can be found here. The railway presents a complex electromagnetic environment made up of many systems including signalling, traction, telecommunications and radiocommunications.

The manufacturer may choose to either follow conformity assessment procedures or to provide accompanying documentation detailing 50121–2 name and site of the FI and the EMC precautions to be taken for the incorporation of the apparatus in order to maintain the conformity of the installation.

The intention of EN was that it would be eh product 501211-2 standard rather than a standard used for CE marking purposes; that was the remit of EN Sorry, your blog cannot share posts by email. 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. Emission and immunity of the signalling and telecommunications apparatus EN Railway applications — Electromagnetic compatibility — Part 5: This model can clearly be used in non-EU countries as a means of demonstrating EMC assurance for railways.

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