A1 Type C type D Type M1 type test piece - Magnetic field indicator -45N, 177N, 118N lifting force test block - DC type B standard test block - AC type E standard test block

According to the requirements of GB23906-2009 and NB/T47013-2015 standards, our company has produced lifting force test blocks, standard test pieces and magnetic field indicators.

The standard test pieces are type A1, type C, type D and type M1, which are mainly used to test the comprehensive performance of magnetic particle detection equipment, magnetic powder and magnetic suspension, showing that the surface of the workpiece under test has sufficient effective magnetic field strength and direction, effective detection area and whether the magnetization method is correct.

The magnetic field indicator is a rough check tool for the direction of the magnetic field on the surface of the workpiece being tested, the effective detection area and whether the magnetization method is correct, but it cannot be used as a quantitative indication of the magnetic field strength and its distribution.
