标准简介
This document describes methods for measuring the high-temperature magnetic properties, such as remanence, intrinsic coercivity and maximum energy product, of high coercivity (intrinsic coercivity HcJ ≥ 2 000 kA/m) permanent magnet materials in the temperature range up to 220 °C. This document is applicable to the measurement of the high-temperature magnetic properties of high coercivity permanent magnet materials such as NdFeB and SmCo.
