EN 55022: 2010 was superseded by EN 55032:2012 on 05/03/2017 and ceased to give presumption of conformity with the essential or other requirements of the relevant Union legislation. So why does EN 55022 no longer give presumption of conformity to the EMC Directive 2014/30/EU?

Basically, as per our previous article “EN 55032 & CISPR 32 Multi-Media Equipment” EN 55013, EN 55022 and EN 55103-1 were effectively combined. This mean’s that the requirements of EN 55032 encompassed requirements from three standards along with some additional requirements.

So already have tested your product and have a valid test report against the requirements of EN 55022. You would prefer not to re-test the product against EN 55032 but are now required to declare compliance against EN 55032 on your Declaration of Conformity (DoC) for CE marking under the EMC Directive 2014/30/EU, what could you do?

Maybe investigate the requirements and examine the accepted standard and the superseded standard to find common testing components whilst verifying the products characteristics and the applicable testing required.

Here is a quick brief overview to verify if there is a chance that you can use an existing EN 55022 test report as evidence.

Remembering the product should have been correctly exercised in the worst-case mode for testing using the correct stimulus. This includes exercising the video display with the most complex real video signal that the display is capable of producing.

Radiated emissions

EN 55022:1998 (with no amendments) required ferrites on all cables going to remote/support equipment this can impact the Radiated emissions results. Therefore radiated emissions below 1GHz performed in accordance with EN 55022:1998 (with no amendments) should be used with caution if not all.

EN 55022:1997 and EN 55022:2006 had no requirements to measure above 1GHz for Radiated emissions, therefore may not demonstrate evidence to EN 55032 if the highest frequency generated or used is more than 108MHz.

If the product is not a Home satellite receiving systems and was tested in accordance with EN 55022: 2010 Radiated emissions, the methods and limits align with EN 55032.

Conducted emissions (AC Mains)

This usually is covered with the LISN capability and characteristics, not much else has changed with the testing methods. If the product was tested in accordance with the EN 55022: 2010 conducted emissions (AC mains port) the methods and limits align with EN 55032.

Conducted emissions (Wired Ports)

Does the product have wired ports such as LAN, CATV, PSTN, xDSL, ISDN or any other widely dispersed network single-user or multi-user connection?

If so “Asymmetrical mode conducted emissions” is required in EN 55032, this testing is similar in most cases to the testing performed for telecommunication port testing of EN 55022: 2010 provided the method used the correct ISN (not the same ISN as used for 55022:1998*). Their other methods, as used for shielded cables etc these, on the whole, should also be similar if not the same.

*EN 55022:1998 used a different ISN than in EN 55022: 2006, these significant changes to ISN can affect the telecommunication port measurement results

If the product was tested in accordance with EN 55022: 2010 conducted emissions (wired ports/telecommunication port) the methods and limits align with EN 55032.

What is not covered in EN 55022 to show conformity to EN 55032

  • Conducted Emissions – Fibre Optic with metallic shield or tension members ports
  • Conducted Emissions at antenna ports
  • Conducted Emissions at broadcast receiver tuner ports
  • Disturbance voltage at antenna terminals
  • Conducted Emissions at TV broadcast receiver tuner ports with accessible connectors
  • Conducted Emissions at RF modulator output ports
  • Conducted Emissions at FM broadcast receiver tuner ports with accessible connectors
  • Radiated emissions for Home satellite receiving systems


As the supplier, it is your responsibility to ensure compliance with the regions compliance requirements and complete any required declaration. Both the RCM for Australia and New Zealand and CE for Europe is based upon “self-declaration of compliance”. We advise that if you do not have the technical competency to ensure that all the compliance requirements are met that you seek assistance from a person or party that are competent prior to complete and sign your DoC. EMC Bayswater provides accredited EMC testing in accordance with EN 55032 if you need full or partial compliance testing.
