The overall aim of the project is to support standardisation in electromagnetic compatibility (EMC) through the introduction of new, validated, and traceable emissions measurement methods for the revision of and forthcoming development of CISPR EMC standards.

  1. To develop traceable electromagnetic emissions measurement methods optimised for in situ assessment of large-size/high-power equipment and to validate the proposed test procedures in harsh environments (e.g., factory premises and photovoltaic installations), which requires development and improvement of live impedance measurement methods in low (30 Hz – 150 kHz) and high (150 kHz – 30 MHz) frequency ranges for conducted emission testing with a target uncertainty of 6 dB. This also includes the characterisation of influence factors such as non-stationary interferences and sources of background noise, correcting the impact of transient interference, and defining a measurement protocol for selecting adequate antenna location, height, and polarisation, and other relevant parameters for the radiated emissions test setup. A report on the methods will be submitted to CISPR/CIS/B/WG7 to support the development of the forthcoming CISPR 37.
  2. To provide metrological evidence of the validity of time-domain electromagnetic interference (EMI) measurement systems, based on direct sampling techniques, and to define standardisable conditions at which the usage of oscilloscopes/baseband digitisers is acceptable or preferred in comparison to measuring receivers based on frequency sweep or stepped scan techniques. The estimation of the uncertainty in time-domain EMI measurement systems will be addressed. A report recommending an amendment of Annex B and Annex C of the current CISPR 16-1-1 standard will be submitted to CISPR/CIS/A/WG1 & WG2.
  3. To improve the standard calibration method for the response to pulses of measuring receivers through a complete waveform specification of the calibration pulse generator. To develop alternative reference waveforms with well-defined mathematical description and spectral properties to include in standards as a means of validating the weighting function of the detectors, thus reducing the uncertainty of the receiver’s response to pulses calibration to 0.2 dB. A report on the proposed calibration methods for the response to pulses of measuring receivers will be submitted to CISPR/CIS/A/WG1 & WG2 to support amendment of CISPR 16-1-1.
  4. To redefine the standard amplitude probability distribution (APD) measuring function in EMI measuring receivers as part of the emissions compliance assessment based on the communication quality metrics. To define the criterion for establishing emissions limits based on APD measurements making it part of the emission compliance assessment. A report on the redefined APD measuring function will be submitted to CISPR/CIS/A/WG1 & WG2 and CISPR/CIS/B/WG1 to support amendment of CISPR 16-1-1 and CISPR 11 respectively.
  5. To contribute to the standards development work of the technical committees CISPR/CIS/A/WG1 & WG2 (supporting revision of CISPR 16-1-1), CISPR/CIS/B/WG1 (supporting revision of CISPR 11), and CISPR/CIS/B/WG7 (supporting development of new CISPR 37) to ensure that the outputs of the project are aligned with their needs. To communicate quickly to those developing the standards and to those who will use them (test laboratories and manufacturers related to IoT, E-mobility, and technologies), and in a form that can be incorporated into the standards at the earliest opportunity.
