Quality control and sampling plan: sampling plan for magnetic properties or dimensional attributes is performed according to the customer's specific requests. Otherwise we use mil standard 105d sampling plan for normal inspection.Test equipment: * the magnetic properties of test samples are determined using a modern bh tracer potting a full loop demagnetization curve.* high accuracy calibrated gaussmeters, fluxmeters, and some other necessary measuring tools are used for appropriated parts.Physical and magnetic tolerance: in the absence of clear instruction on magnetic and physical tolerances, we use magnetic material producers association (mmpa) standard specification for permanent magnet material as a guideline.Processing
