BS EN IEC 60404-8-1:2023 - TC

This standard BS EN IEC 60404-8-1:2023 - TC Tracked Changes. Magnetic materials is classified in these ICS categories:

• 17.220.20 Measurement of electrical and magnetic quantities
• 29.030 Magnetic materials

IEC 60404-8-1:2023 specifies minimum values for the principal magnetic properties of, and dimensional tolerances for, technically important permanent magnet (magnetically hard) materials. For information purposes only, this document provides values for the densities of the materials and the ranges of their chemical compositions. This fourth edition includes the following significant technical changes with respect to the previous edition: a) recently developed anisotropic REFeB hot deformed magnets and anisotropic HDDR REFeB bonded magnets are included; b) high energy Ca-La-Co ferrites stabilized by La and Co substitution are included; c) new and high-performance grades of REFeB and RE2Co17 sintered magnets and isotropic REFeN bonded magnets are added.
