We shall wait with interest! This means that transient emissions, such as those due to pantograph bounce or shoegear gapping are included in the actual measurement. Immunity testing may be largely impractical on-site for large systems 5021-2 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.

EN — Railway applications: Weathering effects, aging, vibration, solar and reliability testing Consulting and debug Fn Standards We have experience with a wide range of standards and regulations. At this stage it may simply define the EN x: 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.

The manufacturer, at his option, can choose for this to be assessed by a third party Notified Body.

Some of the more common standards for rail applications we can help you with. The Impact of the FI Requirements on the Railway Railway infrastructure controllers will need to appreciate the implications and implement policy. In this instance a reasonable approach is to task each sub-contractor with providing documentary evidence that his product is compliant with appropriate standards. Some of the more common standards for rail applications we can help you with include: Where products are too physically large to be assessed in a test chamber, we can test in situ.

It should be 5121-2 that the FI regulatory regime came into effect in July 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 to be taken for the incorporation of the apparatus in order to maintain the conformity of the installation.

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. These standards have also found international acceptance resulting in their implementation in equipment specifications from Hong Kong and Singapore for example.

These specific provisions need to be used in conjunction with the general provisions in EN This European Standard is intended to define the electromagnetic environment of the whole railway system including urban mass transit and light rail system. This model can clearly be used in non-EU countries as a means of demonstrating EMC assurance for railways.

This series describes the EMC requirements for the rail sector and includes the following standards:. The structure of the standards and the way in which they are subdivided has not changed since the original publication.

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

These emissions should be assumed to exist at all points in the vertical planes eb are 10 m from the centre lines of the outer electrified railway tracks, or 10 m from the fence of the substations. 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.
