The test volume of a coil is a three-dimensional area centered within the
coil periphery and extending outwards in all directions, where the field
varies by no more than ±3 dB. The test volume area should fully
encompass the EUT during testing. Illustrated in Figure 20, as an example,
is the test volume for a 1m x 1m inductive standard coil.

The test volume is determined by establishing a fixed magnetic field with
the coil in question, with no EUT present. Magnetic field measurements
are then performed successively, while systematically and incrementally
adjusting the position of the field probe within the field between
measurements. Refer to the IEC 61000-4-8 standard for more information.
