This Technical Report provides the results of an international comparison of measurements of the magnetic moment, using vibrating sample magnetometers (VSM) and superconducting quantum interference device (SQUID) magnetometers. The basic aim of this comparison is to verify the degree of reproducibility of the method, a prerequisite for the prospective development of a related IEC measuring standard. The existing ASTM Standard A894/894M-00 is devoted to the determination of the saturation magnetization of nonmetallic magnetic materials. Ten different research laboratories, listed in Annex B, agreed to participate in the comparison exercise. Each laboratory was assumed to have appropriate traceability of measurements and was required to determine the measurement uncertainty according to the "ISO/IEC Guide to the expression of uncertainties in measurement". The responsible body is DKE/K 171 "Magnetische Legierungen und Stahl" ("Magnetic alloys and steel") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
