This standard applies to electrical equipment using signals in the frequency range 1,6 MHz to 30 MHz to transmit information on low voltage electrical systems, either on the public supply system or within installations in consumers’ premises.
It does not specify the signal modulation methods nor the coding methods nor functional features. Environmental requirements and tests are not included.
The immunity requirements have been selected so as to ensure an adequate level of immunity for apparatus at residential, commercial and light industrial premises (Class 1 environment), and industrial premises supplied from a dedicated HV/MV or MV/LV transformers (Class 2 environment).
The severity levels required by this standard may not cover extreme cases which may occur in any location but with a low probability of occurrence. In special cases situations will arise where the level of disturbances may exceed the levels specified in this standard (e.g. where a hand-held transmitter is used in proximity to an apparatus). In these instances special mitigation measures may be required.
