前 言
本标准NB/T47013《承压设备无损检测》分为以下13个部分:
——第1部分:通用要求;
——第2部分:射线检测;
——第3部分:超声检测;
——第4部分:磁粉检测;
——第5部分:渗透检测;
——第6部分:涡流检测;
——第7部分:目视检测;
——第8部分:泄漏检测;
——第9部分:声发射检测;
——第10部分:衍射时差法超声检测;
——第11部分:X射线数字成像检测;
——第12部分:漏磁检测;
——第13部分:脉冲涡流检测。
本部分为NB/T 47013的第5部分:渗透检测。
本部分按照GB/T 1.1—2009《标准化工作导则第1部分:标准的结构和编写》给出的规则起草。
本部分代替JB/T 4730.5—2005《承压设备无损检测 第5部分:渗透检测》,与JB/T 4730.5—2005相比,主要技术变化如下:
——扩大了检测温度适用范围;
——修改了规范性引用文件;
——增加了工艺规程和安全的内容。
本部分由全国锅炉压力容器标准化技术委员会(SAC/TC262)提出并归口。
本部分起草单位:合肥通用机械研究院、中国特种设备检测研究院、机械工业兰州石油化工设备检测
