This European Standard applies only to newly manufactured static energy meters of accuracy
class 1 or higher, for the measurement of alternating current electrical energy or direct current
electrical energy used by trains for following power supply:

- 25 kV (single phase) at 50 Hz;
- 15 kV (single phase) at 16,7 Hz;
- 3 kV, 1,5 kV and 0,75 kV d.c.

It applies only to static meters consisting of a measuring element and register(s) enclosed
together in a meter enclosure.
It does not apply to
a) portable meters,
b) data interfaces with on board systems,
c) data management system,
d) data interfaces with telecommunication system,
e) on-board global measurement systems; additionally, if voltage and current transducers are considered of accuracy class 0,5. If these transducers are multi-service, specific and separate outputs will be considered.
