磁粉探伤机(仪)是一种检测铁磁性材料工件表面和近表面的裂纹及其他缺陷的无损检测设备。近年来其使用量不断增加,要求也不断提高,由于没有检定规程,2011年1月21日,国家质检总局颁布了JJF1273-2011《磁粉探伤机校准规范》。JJF1273-2011适用于交流、直流(半波整流或全波整流)磁粉探伤机的校准,不适用于电磁轭探伤机(仪)、旋转磁场探伤机(仪)等磁轭式探伤机(仪)的校准。此
Magnetic particle inspection machine (instrument) is a non-destructive testing equipment for detecting cracks and other defects on the surface and near surface of ferromagnetic materials. In recent years, its use continues to increase, the requirements are also rising, because there is no verification procedures, January 21, 2011, AQSIQ issued JJF1273-2011 “magnetic particle inspection machine calibration standards.” JJF1273-2011 is suitable for the AC and DC (half-wave rectification or full wave rectification) magnetic particle inspection machine calibration does not apply to yoke flaw detector (instrument), rotating magnetic field testing machine (instrument) Calibration. this
