Abstract： ISO4967-2013 Steel-Determination of Content of Nonmetallic Inclusions was deeply analyzed. The existing problems in standard spectrum diagram, classification of type and series of inclusions, rating and inspection method were compared with ASTM E45-2018a. Some specific suggestions were proposed, e.g., the evaluation method of coexisting coarse and fine inclusions in the same field of view should be improved and clear, the divergence in evaluation of DS inclusions and oversized D inclusions, as well as the revision and modification of incorrect images for standard rating. The study was to standardize the evaluation method and eliminate the ambiguity, thus advancing the revision of standards, and improving the scientificity and accuracy of inclusion rating.
