    General Physical Imperfections

    Under Normal conditions of handing, shipping, assembly and service, Precision acceptance criteria allows imperfections such as minor hairline cracks, porosity,voids, cold loose chips or particles. Additionally, the condition of flow, shrinkage, pipe and other surface anomalies of the type commonly found in cast or sintered magnets shall be judged acceptable if the following conditions are met:

    1, The magnet meets the minimum magnetic performance criteria agreed upon.

    2, The imperfections do not create loose particles or other conditions which will interfere with proper functioning of the end use device.

    3, Visual imperfections do not extend more than fifty percent 50% through any cross-section.

     

     

     

     

    3,What general physical imperfections are present under normal conditions?

     

    Precision Magtech's standards include Alnico materials, castings and sintered rare earth materials. The standard was developed by Precision Magtech Magnetic Technologies from best practice experience and from MMPA (Magnetic Materials Producers Association) Specification Standard for Materials No. 01 00-00.
