Report on the 14th joint cross-border EMC market surveillance campaign on USB hubs (2021/2022)

On 19 January 2023, the European Commission published a report titled ‘Report on the 14th joint cross-border EMC market surveillance campaign on USB hubs (2021/2022)’. This report provides an overview of the findings of a campaign on USB hubs to assess the compliance of the equipment under test (‘EUT’), samples taken from the European market, with the essential requirements and also with the formal requirements of the EMC Directive 2014/30/EU. The report also makes recommendations on next steps and future actions. In short:


Administrative compliance

  • The results of the administrative assessment of 78 EUT showed:
    • 66% of EUT were considered administratively compliant.
    • 90% of EUT had the correct CE marking.
    • Declarations of Conformity (DoC) were available for 64 EUT; and 44 of them were compliant.
    • From the requested 29 Technical Documentation (‘TD’), 8 were found to be compliant (28%)


Technical compliance with harmonised standards

  • For the purposes of this campaign, technical compliance is to be understood as compliant with an applicable harmonised standard.
  • The results of the technical assessment of USB hubs showed that no issues were found for 63% of 78 tested EUT for disturbance emissions.


Summary of Results

  • Fourteen national Market Surveillance Authorities (‘MSA’), all of them EMC ADCO members, participated in the campaign.
  • 78 types of products were assessed between the 1st July 2021 and the 31th March 2022. In general, the level of compliance with the administrative and technical requirements was considered as low.
  • Overall, 47 % of the Equipment Under Test (‘EUT’) were assessed as compliant. Based on this campaign EMC ADCO has formulated conclusions and recommendations which can be found in Chapter D of the report.
