4.2 Principle
Replace the first sentence of the first paragraph with the following:
The relative magnetic permeability of a feebly magnetic test specimen is determined from the
magnetic polarization J and the corresponding magnetic field strength H measured using the
circuit shown in Figure 1 or Figure 5, using
Figure 1 – Circuit diagram for the solenoid method
Replace the existing title of Figure 1 with the following:
Figure 1 – Circuit diagram for the solenoid method with withdrawal of test specimen
Add a new Figure 5 with title and key, after Figure 1 and the note located below it, as follows:

method with withdrawal of test specimen, the search coil shall be wound on a nonmagnetic,
non-conducting former. Typically, for test specimens up to 30 mm in diameter, the internal
diameter of the aperture in the search coil is 32 mm to allow
