Railway EMC Testing

Railway EMC testing standards were formulated to protect the outside world from Electromagnetic Interference and to ensure railway sub systems, both trackside and installed on rolling stock, are Electromagnetically Compatible.

Railway EMC standards are mandated in the EMC legislation of some countries (such as EU member states under the CE Marking EMC Directive) and are specified in Railway Operator Contracts and Australian State Government Standards.

EMC compliance for ACMA

Global Approvals – Railway EMC Experts

Global Approvals are experts in Railway EMC Compliance and Railway regulatory requirements. We have extensive experience is preparing Railway EMC test plans,  Railway EMC Control & Management plans, trackside EMC testing of rolling stock, trains and trams and laboratory EMC testing of rolling stock apparatus.

We have 20 years of experience testing in the field and in the lab and have acquired a wealth of railway EMC knowledge.

EMC Control & Management Plans

Global Approvals prepare comprehensive EMC Control and Management Plans and EMC Studies for various railway facilities and infrastructure projects. These plans often encompass EMI site and laboratory testing which can be arranged as part of the service.

Plans are typically prepared in accordance with AS/RISSB 7722 : 2016 – EMC Management.

We work with you through all stages of the project from initial tendering through to final commissioning.

EMC Test Plans

EMC Testing to standards such as EN 50121-3-2 and EN 50121-3-1 must be completed in accordance with a detailed EMC Test Plan.  We can prepare these for you and then perform or manage the entire testing process.

EMC Site Testing

Rolling Stock (Trains and Complete Railway Vehicle) must comply with Railway EMC Standard EN 50121-3-1. Compliance is specified in Government Railway Standards and Railway Operator Contracts for supply of rolling stock.

The whole Railway System (ie railyard) must comply with EN 50121-2.

Both standards specify radiated emissions limits for unintentional EMI. Testing is performed with a series of EMC antennas (active loop antenna for measuring radiated magnetic emissions depicted), typically positioned 10m from the equipment under test or boundary.

Global Approvals can provide this testing service all around Australia.

EMC Laboratory Testing

Rolling Stock Apparatus (equipment installed on trains) must comply with Railway EMC Standard EN 50121-3-2.

Emissions and Immunity limits are specified for the enclosure, power and signal ports.

Existing test reports can be analysed to determine the liklihood of compliance.

Global Approvals can arrange testing at reputable, A2LA or NATA accredited test laboratories and manage the entire process from start to finish.

Project Experience

Global Approvals staff have been involved in countless Railway EMC projects over the past two decades, spanning EMC testing of Rolling Stock (trains and rail vehicles), EMC testing of Rolling Stock Apparatus (equipment installed on trains), Railyard EMC testing, preparation of EMC testing, acceptance, management and control plans and sign-off (NATA authorised signatory) for countless EMC test reports to standards such as EN 50121-3-1, EN 50121-3-2, EN 50121-2, EN 50121-4 and EN 50121-5.

Standards are available through SAI Global.

TIP: When selecting COTS equipment and sub-systems for Railway Applications try to ensure it is compliant with industrial EMC standards such as EN 61000-6-2 and EN 61000-6-4 (or equivalent) to increase the liklihood of compliance with Railway EMC Standards (of course compliance with specific Railway EMC Standards is best!) .
