dipole moment by means of a calibrated permanent magnet
sample
8.4 Withdrawal method

sigma[s]
12 Calibration of the measuring device for the saturation value
of the magnetic dipole moment
13 Uncertainty of measurement
14 Test report
Annex A (informative) Measurement of the specific saturation
magnetic polarization of test specimen longer than the
homogenous area of the Helmholtz coil
Annex B (informative) Measurement of ferromagnetic specimens
with high saturation magnetic field, e.g. a hardmetal
specimen with high cobalt content
Annex C (informative) Measurement of a test specimen with a
small mass, e.g. a hardmetal specimen of a cobalt content
less than 50 mg
Annex ZA (normative) Normative reference to international
publications with their corresponding
European publications
Applies to all ferromagnetic materials and particularly aimed at the measurement of the magnetic dipole moment of permanent magnet (magnetically hard) materials and the measurement of the specific saturation magnetic polarization of cemented carbide materials having a ferromagnetic binder.
