Foreword
This standard is equivalent to international standards ISO 11531.1994 "metal material ear test" (in English). For ease of use, this standard
I made the following editorial changes.
a) "this International Standard" be replaced by "this standard";
b) use a decimal point instead of a decimal comma ",". ",";
c) Remove the preface to the international standards;
d) a reference to the file by pressing the corresponding national standards were changed.
The standard proposed by China Iron and Steel Association.
This standard is under the jurisdiction of the National Steel Standardization Technical Committee.
This standard was drafted. Shanghai Exit Inspection and Quarantine, Wuhan Iron and Steel Co., Ltd., Metallurgical Industry Information Standards Institute.
