Foreword
This standard is identical with IEC 60404-4.2000 "magnetic materials --- Part 4. Methods of measurement of dc magnetic soft magnetic material" (English
Version), the main content and structure of IEC 60404-4.2000 agreement.
For ease of use, this standard has been modified following editorial.
--- The term "this part" (referring to IEC 60404 Part 4) to the "standard";
"." --- With a decimal point instead of a comma as the decimal point, "";
--- Delete foreword international standards;
--- References by corresponding national standards and industry standards were changed;
--- Rearrange the picture number and location.
This standard replaces GB/T 13012-1991 "Methods of measurement of dc magnetic properties of steel", but instead of GB/T 3657-1983 "soft close

Methods of measurement of dc magnetic soft magnetic materials
1 Scope
This standard specifies the method for use in a closed magnetic circuit or loop-like magnetic permeability soft magnetic material measuring DC magnetic properties. Ring-like method is suitable for
Sheet stacking ring-like, or whole solid ring-like ring and sintered samples.
This standard specifies the following two methods.
a) an annular sample method, mainly applied to the magnetic field strength measured at 10kA/m or less;
b) permeameter method for measuring the magnetic field strength in the range between (1 ~ 200) kA/m of.
