5.0 MECHANICAL CHARACTERISTICS
The following general specifications are for mechanical characteristics and visual imperfections.
5.1 Surface Conditions
5.1 .1 All magnet surfaces shall be free of foreign materials which would tend to hold or collect extraneous particles on the magnet surface in the unmagnetized condition.
5.2 Chips
5.2.1 Magnets shall be free of loose chips. They shall be free of imperfections which will result in loose chips or particles under normal conditions of handling, shipping, assembly and service.
5.2.2 A chipped edge or surface shall be acceptable if no more than 10 percent of the surface is removed, provided that no loose particles remain at the edge or surface, and further provided the magnet under examination meets the magnetic specification agreed upon between the producer and user.

5.3 Other Physical Imperfections
5.3.1 Imperfections such as minor hairline cracks, porosity, voids, and others, all of the type commonly found in sintered metallic magnets, shall be judged acceptable if the following conditions are met:
5.3.1.1 The magnet meets the minimum magnetic performance criteria agreed upon.
5.3.1.2 The imperfections do not create loose particles or other conditions which will interfere with proper functioning of the end device.
5.3.1.3 Cracks shall be acceptable provided they do not extend across more than 50 percent of any pole surface.
5.4 Other Conditions
5.4.1 Non-destructive inspection methods such as the use of penetrants, microscopy, magnetic particle analysis, ultrasonic inspection, or x-ray shall not be acceptable able methods for judging the quality of
sintered rare earth magnets except as provided in Section 5.4.2.
5.4.2 In cases where the magnet is expected to withstand abnormal conditions or stresses, such conditions must be previously specified and a mutually acceptable service test devised to assure that the
magnet shall not fail under the specified service conditions. Such tests should duplicate service conditions with appropriate safety factors.
