< 70 43
70 – 200 46
200 – 300 50 20
300 – 400 52 20
400 – 600 55

The limiting values at other frequencies (within the AM band of 535 – 1605kHz or higher) may be extra/intrapolated by using the appropriate graph in Figure B12 of CISPR 18-1 – 1982 or Figure B1 in Appendix B of AS/NZS 2344:1997. The values may be extra/intrapolated for other measurement distances as per the appropriate graph in Figure 2 of CISPR 18-1.

** Horizontal distance from the vertical projection to the ground of the outermost phase conductor. All measurements shall be made at 2m above ground level.
