Foreword

This Standard was drafted as per the rules specified in GB/T 1.1-2009.

This Standard replaced SJ/T 10410-2002 Permanent Ferrite Materials.

Compared with SJ/T 10410-2002, this Standard made the major changes as follows.

--- Among the sintered permanent ferrite material designations, delete Y22H, Y26H-

2, Y27H, YN1T, YN4T and YN4TH; add Y33H-2, Y41, Y41H, Y42, Y42H, Y43.

--- Normative references adopt the latest version; the test methods for main

magnetic properties of the materials, and the specification, size and appearance

requirements of the test sample shall be as specified in GB/T 3217-2013.

Please note that some contents of this document may involve the patents. The issuing

agency of this document does not assume the responsibility to identify these patents.

This Standard shall be under the jurisdiction of National Technical Committee on

Magnetics and Ferrite Materials of Standardization Administration of China (SAC/TC

89).
