摘　　要：对比分析GB/T 10561—2005《钢中非金属夹杂物含量的测定标准评级图显微检验法》与ASTM E 45—2013《测定钢中杂质物含量的标准试验方法》的异同,并提出非金属夹杂物检验标准的修订意见。GB/T 10561—2005描述了用标准图谱评定压缩比≥3的轧制或锻制钢材中的非金属夹杂物的显微评定方法,ASTM E 45—2013包含了多种测定锻、轧钢中非金属夹杂物含量的测定方法。这两个标准在标准结构、适用范围、检验方法、标准评级图谱、试样的选取、夹杂物分类与评定方法及结果表示等方面存在不同程度的差异,但在视场的选取、放大倍数、夹杂物评级界限等方面基本相同。Comparatively analyzed in the article are GB/＇F 10561--2005 Determination of Contents of Nonmetallic Inclusions--Micrographic Test Method Using Standard Plate and ASTM E 45--2013 Standard Test Methods for Determining the Inclusion Content of Steel to identify the similarities and differences, and accordingly proposal for revision of the standards for determining nonmetallic inclusion is put forward. GB/T 10561--2005 describes the micrographic evaluation method using the standard plates for determining the nonmetallic inclusions of the rolled and forged steel goods with compression ratio ≥3, while ASTM E 45-2013 specifies a number of methods for determining nonmetallic inclusions of forged and rolled steel goods. There are more or less differences between the two standards in terms of standard composition, applicable scope, test method, standard rating plate, specimen selection, inclusion classification, and evaluation method and result presentation, etc. However they are basically similar when it comes to such issues as selection of field of view, amplification times and rating limit for inclusion, etc.
