• EN 55014 : Limits and methods of measurement of radio disturbance characteristics of electrical motor-operated and thermal appliances for house hold and similar purposes, electrical tools and similar apparatus.
  THe main specificity is that this standard allows more important levels for transient disturbances with low duration time and low repetition rate.
• EN 55015 : Limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment
