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.
