This seventh constitutes a technical revision. The significant technical changes are:
- the addition of the values of 230 V (50 Hz) and 230/400 V (60 Hz) to Table 1;
- the replacement of the utilization voltage range at LV by a reference to the relevant standard and an informative annex;
- the addition of the value of 30 kV to Table 3;
- the replacement of the value of 1 050 kV by 1 100 kV in Table 5.
It has the status of a horizontal standard in accordance with IEC Guide 108.
