I believe that Clause 7.2 contains an error. Clause 6.2.1 requires the field variation be no more than +/- 3 dB over the volume of the EUT. For a 1 m square loop, the test volume is 0.6 m x 0.6 m x 0.5 m (h) with the loop centered on the test volume. Therefore, a vertically oriented loop would be spaced at least 0.2 m above and below an EUT that would fit within the test volume.
However, the first paragraph in Clause 7.2 requires that the equipment be raised 0.1 m above the ground reference plain. - no more and no less. But, the third paragraph of Clause 7.4 says that 0.1 m is the minimum distance. It appears that Clause 7.2 is in error and Clause 7.4 is correct (it to is wrong for a 1 m loop, but would be correct for a 0.5 m and smaller loop). Comments?
