This standard applies to electrical equipment using signals in the frequency range of 95 kHz to 148.5 kHz for transmitting or receiving information over low-voltage systems in residential, commercial, and light industrial environments. It is relevant only for the parts of the equipment involved in communication; other functions must comply with applicable immunity standards. The standard aims to limit interference between mains communication equipment operating in different frequency bands and ensures electromagnetic compatibility (EMC). It specifies essential immunity requirements and testing methods for continuous and transient disturbances, both conducted and radiated, including electrostatic discharges. Limits are set for products used in these environments, but extreme cases may require additional mitigation measures. Safety considerations are not included in this standard.
