摘　　要：通过对NB/T 47013.4-2015相关条款的讨论,对检测方法分类、连续法停止磁化的时机和连续法的磁化通电时间、剩磁法施加磁粉或磁悬液、在用承压设备的磁粉检测等内容提出了不同的观点,并提出了修改建议,有助于该标准的进一步完善。This paper aims to discuss the relevant clauses of NB/T47013.4-2015. Different views for the classification of testing methods, the time to stop magnetization by continuous method, the magnetization energization time of continuous method, the application of magnetic powder or magnetic suspension for the residual magnetization method, and the magnetic particle detection of in-use pressure equipment were put forward. The revision suggestions were also put forward, which may help to further improve the standard.
