DL/T 821—2002与JB/T 4730.2—2005射线检测标准技术部分的比较和分析

Comparison and Analysis Between DL/T 821—2002 and JB/T 4730.2—2005 in Terms of Radiographic Testing Technology

DL/T 821—2002是电力行业专用的射线检测标准,JB/T 4730.2—2005是承压类特种设备行业推荐通用的射线检测标准。通过对两个标准射线检测技术部分相关内容有针对性的对照和比较,对存在的差异和有可能对检测结果造成的影响进行分析,进一步加深对相关条款的认识和理解,为做好射线检测技术管理工作起到指导作用。

DL/T 821--2002 is a standard of radiographic testing specialized in electric power industry and JB/T 4730. 2-2005 is the general standard of radiographic testing recommended by pressure-bearing special equipment industry. This paper, through a purposeful contrast and comparison of the relevant technology content in these two standards of radiographic testing, analyzed the existing difference between them and the potential influences on testing results, offered us a better understanding of relevant clauses and a guiding function to the effective management of radiographic technology.
