对GB/T 10561标准进行修订时,主要修改了DS类夹杂物定义、夹杂物计算公式、夹杂物评级图,增加了标准术语,钢管的取样图,复合夹杂物、析出相的评定方法及化学特征表示,B法检验的两种结果表示方法等。从标准的术语、原理、取样、检测方法等方面详细介绍了标准GB/T 10561的修订内容,以帮助检测人员更好地执行新标准,提高非金属夹杂物评级的准确度。

When the GB/T 10561 standard was revised, the definition of DS inclusions, the calculation formula of inclusions and the rating diagram of inclusions were mainly modified, and the standard terminology, the sampling diagram of steel pipes, the evaluation method and the representation of chemical characteristics of composite inclusions and precipitated phases, the two results of B method were added. The revised content of GB / T 10561 was introduced in detail from the aspects of standard terminology, principle, sampling and detection method, so as to help inspectors better implement the new standard and improve the accuracy of non-metallic inclusion rating.
