scope:

This Technical Report 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 is a Technical Report covering the different standards for HF Power Line produced by SC205A.
It points to related documents about:
- Frequency bands, coexistence and filters.
- Limits for the terminal output levels in the operating band.
- Limits for conducted and radiated disturbance (product & installation EMC).
- Measurement methods.
It does not specify the signal modulation methods nor the coding methods nor functional features.
Environmental requirements and tests are not included.
The requirements have been selected so as to ensure an adequate level of EMC and EMI for all
apparatus (e.g. including residential, commercial, light industrial and industrial premises).
The severity levels required by this Technical Report 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 Technical Report (e.g. where a handheld
transmitter is used in proximity to an apparatus). In these instances special mitigation measures may be required.
