IEC 60502-1?
Decision:
The sample requirements for each type of cables per IEC 60502-1 shall be as follows:
7 i0 ]! d% U  P# N1kV cables:
1 sample of approximately maximum cross-section with copper or aluminium conductor.
1 sample of maximum number of cores and middle cross-section with aluminium or copper conductor.
3kV cables and 1kV cables simultaneously:
1 sample of approximately maximum cross-section with copper or aluminium conductor for rated voltage of 3kV.
