Annexes
A (normative) Method of measurement of the frequency range
              over which a transmitter device detects a
              signal from another device in the frequency
              range 125 kHz to 140 kHz
B (normative) Method of measurement of the spectral distribution
              of a transmitting device's signal in the frequency
              range 125 kHz to 140 kHz
C (normative) Methods of measurement (9 kHz to 30 MHz)
D (normative) Methods of measurement of disturbance power
              (30 MHz to 1 GHz)
E (normative) Attenuation characteristics of measuring instrument
              above 150 kHz
F (informative) Design for a single artificial network intended
                to show the performance of a signalling system

Applies to electrical equipment using signals in the frequency range 3 kHz to 148,5 kHz to transmit information on low voltage electrical systems, either on the public supply system or within installations in consumers' premises. Does not specify the signal modulation methods nor the coding methods nor functional features (except those for the prevention of mutual interference). Environmental requirements and tests are excluded. Covers definitions, frequency bank, access protocol, transmitter output voltage, disturbance limits, test conditions and inadvertent operation.
