Note: the CVC EMC service page is JavaScript-rendered and did not return itemised content, so the EMC breakdown below is assembled from CVC's stated national-centre scope (safety/performance/EMC across these product families) and maps each service to its governing IEC/GB standard family rather than a fetched test list.
